On the report podium of the working meeting, Wang Hao made a report on the particle characterization program.

He mainly gave a brief explanation of the idea of the program and each part of the data analysis.

This report is not an overall analysis of the program, nor is it intended to make it clear to everyone how the program is designed, but only to explain the design ideas of the program, as well as some problems in use, and it does not involve some difficult points of understanding.

Most of the people in the room could understand it, and they understood the overall idea, so they had a general understanding of the program.

That's enough.

Wang Hao doesn't need to explain the details, because it's just a program, and it's not a group of programmers, and the main purpose of his report is to let the relevant personnel know how to use the program and what situations are effective.

After completing all the explanations, Wang Hao made a simple summary, "So this program is effective for particle characteristic analysis, and the specific effect depends on the specific situation." ”

"We are analyzing the data for group F, and we need to fine-tune the program to a certain extent. As long as you understand the structure of the whole program, and then do similar data analysis, you can use computer analysis to complete. ”

After Wang Hao finished the last sentence, he bowed slightly to the audience, and then walked off the podium.

The venue also erupted in warm applause.

They not only applauded Wang Hao's report, but also believed that Wang Hao's participation in the experimental work made a great contribution.

This program analysis method will be very helpful for the initial data analysis work in the future, reducing the very complicated workload in the data analysis process.

After Wang Hao stepped down from the stands, several more people came to the stage to make a report, and then the meeting was announced.

During the rest of the meeting, Wang Hao also checked the task situation.

[Task 2]

[Research Project Title: Analysis of CP Destruction of Positive and Negative Corsi Hyperons (Difficulty: S.)] 】

[Inspiration: 14.] 】

"It's a little little......"

Wang Hao frowned slightly when he saw the data, but after thinking about it carefully, he felt that it was normal.

The difficulty level of the latest data analysis task is S-level, and even if the content of the explanation is data analysis, it is not bad to get 14 inspiration points.

In addition, it is important to note that he does not know much about the spectrometer detection data, and without an understanding of the data base, it is very difficult to improve his inspiration.

After the meeting, Wang Hao, He Yi and others were ready to leave.

The Institute was very enthusiastic about Wang Hao, and two academicians, Zhang Yifang and Tian Guilin, including several professors, took the initiative to come and send him.

Tian Guilin shook hands with Wang Hao for the first time, and he was also called by Zhang Yifang when he came to see Wang Hao, but in fact, there was no contradiction between him and Wang Hao.

The two didn't even speak officially, just because Wang Hao designed a program to help the team of Xijing Jiaotong University and Huzhou University complete the data analysis of the upper and lower halves of Area F, resulting in the data analysis report of the seventh working group not being accepted.

This question also comes down to Wang Hao's excellent personal ability, not that he has any contradictions with the Seventh Working Group or Tian Guilin.

Tian Guilin thought about it and felt that it was nothing.

Wang Hao simply didn't know the situation at all, because he hadn't spoken to Tian Guilin, and he didn't expect that the other party would be greatly affected because of him.

The two still shook hands with a smile and exchanged pleasantries.

Then, a group of people slowly walked forward.

Zhang Yifang, Tian Guilin, and Wang Hao were at the forefront, and they once again talked about the work of Puyi detection.

Tian Guilin introduced a lot this time, and he also expressed his understanding of the Puyi detection project, "The number of hyperons is still too small, and if we want to measure the asymmetric signal of positive-negative Cosi hyperon decay, we must make a large number of hyperons, but the scale of our experiment is still too small." ”

"Now we all have a pressure, a sense of urgency, and if foreign institutions complete the research ahead of schedule, our work will be completely meaningless."

This is where a lot of people worry.

There is also competition in scientific research, especially in the same field, and other institutions have achieved results, so all the efforts of those who do research in the same direction will be meaningless.

There are several institutions in the world that do research on the decay of Cosion hyperons, and American has two laboratories, both of which specialize in the targeted 'production' of Cosi hyperons.

If they had completed the study of the Cosiy hyperon first and discovered the asymmetric signal of the positive and negative Cosi hyperons, that is, the 'CP destruction' of the Cosi hyperon, the spectrometer detection project would have lost its meaning, and the efforts they had spent more than ten years would have been in vain.

When the topic came to this, many people fell silent.

Wang Hao smiled, "Academician Tian, don't be so pessimistic. Didn't foreign institutions say that they could make a thousand times more Kosi hyperons? But aren't they the same as not measured out? To a certain extent, it may be that it is not feasible to measure CP destruction by increasing the number of hyperons. ”

When he said this, others were much more relaxed.

Zhang Yifang asked, "Professor Wang, in your understanding, why can't we detect the asymmetric signal of positive-negative Cosi hyperon decay?" Is there a possibility, I just said it could ......"

"The theory is wrong?"

As soon as Zhang Yifang's words came out, the others suddenly fell silent again.

The study of theoretical physics is like this, and even if some theories are recognized by the whole world, they are not necessarily correct.

Nowadays, a large number of physical institutions are conducting research around the particle Standard Model, but no one dares to say that the particle Standard Model is correct.

Even those phenomena that have been discovered, because they are all microscopic phenomena, can only detect some signals, and theory is the analysis and interpretation of signals and data.

Are these explanations necessarily correct?

Just like the well-known string theory in theoretical physics, many top mathematicians and physicists have studied string theory, the most famous of which is Princeton University professor and Fields laureate Edward Witten.

Edward Witten spent his life studying string theory and expanded it to include superstring theory to explain multidimensional space, and the more refined theory of X.

Even the Fields obtained by Edward Witten were a by-product of the study of string theory by virtue of the mathematical logic shaped in the process of perfecting string theory.

If one day string theory turns out to be wrong, it means that Edward Witten has been doing wrong research all his life.

That would definitely be a sad story.

Wang Hao thought for a while and said firmly, "I don't dare to say that the specific physical theory is completely correct, but I think that there is indeed an asymmetry in the decay process of the positive-reverse Cosi hyperon. ”

His words were very firm, even surprising, because he was a pure mathematician, not a theoretical physicist.

The others also feel very good when they hear it, as if they are affirming their own work.

Thinking about his own research on spectrometer detection, the results show that no mathematician has firm confidence in supporting the basic theory of spectrometer detection, and suddenly he also conducted some self-reflection.

Of course, they don't know that Wang Hao has established a research and development task, as long as the task can be established, it means that there is no problem with the foundation.

I dare not say whether the general theoretical direction is correct, but the problem of asymmetry in the decay of positive and negative Cosi hyperons certainly exists, and what the asymmetry specifically illustrates needs to be explained by physicists.

Several people went on to talk about the asymmetry of the decay of the Cosi superon.

Wang Hao still didn't understand something, and he also asked, "It can't be detected now, is it because in the baryon decay, the weak response signal will be masked by the strong reaction?" ”

"This is the main reason, but it is not necessarily, if the theory is correct, it is also related to the detection accuracy and analysis methods." Zhang Yifang explained.

At this time, Wang Hao was suddenly stunned.

When he asked the question just now, he suddenly had a flash of inspiration in his mind, and he carefully recalled that it was 'the action of a force that annihilated the CP signal'.

What do you mean?

Wang Hao knew that "The Gift of Scientific Research" was working, but he still didn't know much about the content that appeared in his mind, so he simply asked directly, "Is it possible that there is a force that annihilates the CP signal?" ”

Instantly, more information comes to mind.

Wang Hao suddenly understood, and was immediately shocked by the system prompt.

[Task 2, inspiration +29.] 】

+29？

Is it really a force? And it is directly related to the data analysis of hyperon decay asymmetry?

Behind the crowd.

A doctoral student walked forward with everyone, and was immediately surprised when he heard Wang Hao's question, and said in his heart, "I just thought, is it possible that the universe rejects positive particles, even if there is a CP signal, it will be annihilated......

"Professor Wang is the same as I thought?"

"But...... How can it be! It's just a random thought, if there was a fifth force, it would have been detected a long time ago. ”

Wang Hao's statement made others think.

Zhang Yifang didn't care, he said with a smile, "As long as you use your imagination, there will be many possibilities." ”

"Professor Wang, you are a top mathematician, if you are interested in this aspect, you can try to engage in theoretical physics research."

Wang Hao tugged at the corners of his mouth when he heard this.

Is this a satire of theoretical physicists, a bunch of madmen who rely on imagination to build mathematical systems?

……

No one can answer the questions raised by Wang Hao, and no one dares to say whether they are correct or incorrect.

In the eyes of others, this is an imaginary problem of theoretical physics, and it is almost impossible to prove it, but Wang Hao knows that there must be some force that annihilates the CP destruction signal of positive-negative Corsi hyperon decay.

Because he gets the information through the feedback of the system, not relying on his own imagination.

"What kind of force is this?"

"Annihilation of the CP signal should be called annihilation, right?"

"Cosmic Annihilation, or Space Annihilation......"

If the discovery can be proven, it will definitely be a super discovery of physics.

This problem is also directly related to the data analysis of positive-negative Cosion hyperon decay, in other words, if the data analysis of positive-negative Cosi hyperon decay can be completed, the problem of discovering 'spatial annihilation force' will definitely arise.

The latter, for a short time, is certainly impossible to prove.

"So, when a problem is solved, a bigger problem is discovered, and it is an unprovable problem."

"Science, the universe, the more you study, the more you feel ......small, the more you feel small."

He shook his head with a wry smile.

That night, Wang Hao returned to Xihai City, rested for a night, and went to Xihai University the next day.

The spectrometer detection experiment took more than a week, and the course was delayed for a week, and Professor Zhou Qingyuan helped bring a retake course of "Probability Theory and Mathematical Statistics".

"Theory of Elementary Numbers" simply stopped for a section.

But it doesn't matter much, and it's easy to talk about electives.

"Algebraic Geometry" asked Zheng Yaojun to help substitute the teacher, and Wang Hao also transferred 1,000 yuan to Zheng Yaojun, because he remembered that the other party asked him to substitute last year and also gave him 1,000 yuan in course fees.

Now it's the equivalent of giving the money back.

In the morning, Wang Hao found Zheng Yaojun, transferred 1,000 yuan to him, and asked about the course by the way.

Zheng Yaojun accepted the money very happily, and said happily, "Next time you ask me to substitute for a teacher, don't give me money, otherwise I won't help?" ”

“……”

Wang Hao was silent but decided not to demolish him.

Zheng Yaojun shook his head and continued, "Seriously, don't look for me next time, let's do it yourself." ”

"Is it difficult, or what?" Wang Hao asked.

"What is the difficulty, I have also talked about "Algebraic Geometry", the main thing is that students are demanding now!" Zheng Yaojun said with a sigh, "When I teach "Differential Equations", many students have reported to me that they are not as good as you, and they are still those students, and they all said that I should not come next time." ”

He also covered his heart with his hand, as if he had been hit hard.

However, Zheng Yaojun is obviously a very cheerful character, and he immediately changed the topic and said, "By the way, I haven't thanked you yet." ”

"Thank me?"

"Don't you know? I recruited a graduate student, in fact, I didn't want to recruit this year, I brought two PhDs under me, but the school said that this student was very good, I read the information, and it was indeed excellent. ”

Wang Hao listened.

"Her name is Hu Lidan, she is really an excellent girl, she has a very thorough understanding of partial differential equations, and she feels that her level is no worse than that of a graduate student."

"Moreover, she rejected Professor Huang Pei, and there were two other doctoral and master's supervisors, so I was persuaded and decided to follow me to study for graduate ......"

Zheng Yaojun said with a smug look.

Wang Hao asked curiously, "Why?" He stared at Zheng Yaojun carefully for a long time, and was 100% sure that Hu Lidan definitely didn't take a fancy to this face.

"Of course, it's by ability!"

Zheng Yaojun said with certainty, "She was hesitant at first, so I told her that I have a big project in my hand, with a fund of 200,000 yuan, you can follow me to do research, and then give you a top subsidy." ”

"This subsidy level is definitely not available in other mathematics masters."

"Uh-huh."

This Wang Hao really believes that most professors engaged in mathematics research basically have no funds in their hands, and they can say that they are 'living very poor'.

Like Zheng Yaojun, a doctoral supervisor with 200,000 projects in his hand can be described as 'rich and handsome in the doctoral guidance industry'.

What's more, Zheng Yaojun still has a small project of 50,000 yuan in his hand, which is not much money but enough to support students.

But......

Is this called ability?

Zheng Yaojun obviously thinks that 'money ability is also ability', he continued, "I also told her that I only brought two PhDs, only you are a graduate student, and when you finish graduate school, you can continue to follow me when you finish graduate school and study for a Ph.D., and when the time comes, the doctoral dissertation will definitely be excellent, and maybe you can get an award." ”

“…… Draw a flatbread? Wang Hao hesitated for a long time and spit out three words.

"What is the meaning of painting flatbread, I am telling the truth!" Zheng Yaojun said, "I have only this one graduate student, and I don't plan to recruit any more next year, when the time comes, focus on a research, three, four, five years, what is strange about the doctoral dissertation award?" ”

Wang Hao nodded approvingly, "That's right." ”

In fact, if you think about it carefully, Zheng Yaojun's conditions are indeed very attractive, his ability level is definitely not bad, and it is only a matter of time before he is promoted to professor.

He only has two PhDs under him, and only one graduate student, so he has time to guide with few students.

In addition, he is also a wealthy and handsome man in the 'mathematics tutor world', with more than 200,000 funds already a lot, maybe he can apply for another excellent young man this year?

At that time, the funding will be from one million, and there will be no problem at all to give students high subsidies.

However, Zheng Yaojun's pride is obviously not his own conditions, but his pride in other professors and doctoral supervisors, who tried to persuade Hu Lidan without success, and he persuaded Hu Lidan to follow him to graduate school.

That's where the pride comes in.

Others didn't do it, but he did, isn't it amazing?

Wang Hao had been listening to the side, and he regretted coming to Zheng Yaojun a little.

This guy has something to do, he likes to brag about it, and follow Zheng Yaojun to study for a graduate school, his ears will probably be very hard, right?

Hu Lidan, let me tell you in advance--

"Amen!"

……

Back in the office of the comprehensive building, Wang Hao said hello to the others, told them interesting things about the spectrometer detection experiment, and then turned on the computer and logged in to the intranet of the large-scale research project of the positron and negative electron collider.

There is a lot of data on the intranet, a lot of papers uploaded internally, and even a small forum for researchers to communicate on the problem.

Wang Hao clicked in and took a look, and found that they were all irrigation posts, and there were even people who shared their lives, and there were also people who traveled abroad to attend conferences, complaining about the local environment and tourist attractions were boring.

Of course, there are some very professional posts.

He glanced at the spectrometer and saw the data.

The data can be viewed at will, the degree of confidentiality is not high, and it is just not open to ordinary people.

In fact, it is the same as the European particle collider, because the data analysis is done in cooperation with many national institutions, and it is impossible to achieve any secrecy, as long as you want to see it, you can see it.

The data detected by the spectrometer mainly contains two kinds of data, one is the basic data, that is, the data uploaded by the experimental test, and the other is the measured data.

Even the measured data looks very chaotic, and professional researchers find problems in these chaotic data.

The main purpose of the spectrometer detection experiment is to detect the CP destruction signal, and the "best performance" of the CP destruction signal is to detect the presence of particles or specific energy after the decay is completed.

It's like two numbers colliding, one is 7 and the other is -6.9, and the sum of the two results in 0.1.

If this 0.1 can be found, it is naturally equivalent to the discovery of CP destruction.

Otherwise, everything disappears, nothing is left, nothing can be detected, and the number '-6.9' will naturally be considered '-7'.

Wang Hao carefully browsed the data, what he had to do was to have a basic understanding of the data, and it would be much easier to study it after understanding.

At the same time, he also thinks about the 'annihilation of space'.

It is difficult to say whether the description of 'spatial annihilation force' is accurate, but there must be an annihilation force, which annihilates the signal of CP destruction and affects the problem of data analysis.

So in what form does this annihilation exist?

Can reality be seen?

Or are there some physical phenomena that are caused by annihilation and the result is mistaken for other reactions?

Zhang Zhiqiang walked over and saw Wang Hao, who was in thought, and sat down in his place with coffee.

Take a sip of coffee and look at the code on your computer.

I rubbed my hair every day, and a few of them were gone.

Wang Hao opened his mouth and asked Zhang Zhiqiang, "Brother Zhang, if, I mean, if there is a cosmic annihilation force that can annihilate particles, what kind of performance do you think it will appear in reality?" ”

Zhang Zhiqiang turned his head and listened, then his mouth was half open and did not close, and a drop of coffee flowed down the corner of his mouth, he quickly wiped it and said, "Your question, let me think about it......"

"Think about it......"

"I think so......"

He thought about it for a long time, and suddenly a flash of inspiration said, "I remember that there is a Japanese anime in it, and there is a god called the god of destruction, this kind of god has a destructive power that can make everything it touches completely disappear." ”

"This destructive power seems to be purple, you can think about it......"

“……”

Wang Hao listened patiently and nodded, then stood up and said, "What you said is very reasonable. ”

"So, I'd better ask the others."
