The next day, Wang Hao spent the next day absorbing knowledge.

He went to the Positron Collision Center again, where he was with the team at Xijing Jiaotong University, and had a clear understanding of the purpose of the spectrometer experiment.

The ultimate goal of this research is to solve the mystery of quark matter and find the problem of the asymmetric origin of positive and antimatter.

The asymmetry of positive and antimatter is a phenomenon that particle physicists have been looking for, and the research first began with the law of "cosmic symmetry non-conservation" proposed by Yang Chenning and Lee Tsung-dao, for which they won the Nobel Prize in physics.

Later, a theory emerged that the 'decay' of positive and negative particles was asymmetrical, and that for every billion positive and negative particles that were annihilated, one positive matter particle was left behind, and eventually made up all the matter in the universe today.

Because of this, there is only positive matter and no antimatter in the universe.

This is an explanation of the source of matter.

In recent decades, particle physicists have been looking for evidence to support their theories, and the way they do this is by studying the phenomenon of 'CP destruction'.

'CP destruction', that is, the phenomenon that the decay process of positive particles and antiparticles is different.

The research method of 'CP destruction' is to study special particles.

The Kosi hyperons produced by the Positron Collider are very important research objects, and the team at the Positron Collider has been studying the decay of Cosi hyperons since ten years ago.

To study Cosi hyperons, we need to study J/psi particles.

The decay of J/psi particles produces 'positive-reverse Cosi hyperons', after which the positive-reverse Cosi hyperons continue to decay until they disappear.

The current experiment is to start the equipment to do new collision experiments, collect enough data, and do detailed research with more accurate measurement and analysis methods, hoping to make new discoveries.

After understanding the overall experimental content, Wang Hao still pays attention to the work of his own team, that is, the work he wants to participate in, after all, experimental research is initially completed by a team of hundreds or thousands of people.

In a team of hundreds, thousands, the power of one person is very limited.

On the morning of the third day, a new experiment began, but no one else could do anything but wait in the room, listening to the hum of the machines outside.

The experiment did not have the magnificence of the collision of particles as imagined, but the sound was very irritating.

You can imagine what happened inside the large equipment, but it was impossible to see it at all, and the people involved in the experiment could only see some bright spots from the detection device.

This is the real particle collision experiment.

The preparation of the experiment took a long time, in fact, the real experiment took a very short time, and the experimental process was an instantaneous collision, most of which was still spent on preliminary preparation and particle acceleration.

Soon, the experiment ended.

There was a humming sound from the machine, but it was noticeably weaker.

In the afternoon, the research team held a work assignment meeting, and Wang Hao's team went to three people, Xue Wenzhuo, he and another physics professor at Xijing Jiaotong University, Dong Zhihui.

When they entered the conference hall, they sat in a seat in the back row, but in front of them was the regular Seventh Working Group, composed of experts from the Institute of High Energy Studies and the team from Capital University.

The seventh working group is not a permanent team, it is also temporarily formed, but it is relatively much more formal, and the working group is led by Academician Tian Guilin of the Institute of High Energy.

Among them, there are also two experts in high-energy physics, several professors of mathematics and physics at Capital University, and the strength of other teams is naturally not at the same level.

They are also responsible for data analysis, and the work includes the Xijing Jiaotong University team.

Working Group VII is the main working group.

There are two subordinate teams, namely the team of Xijing Jiaotong University and the team of Huzhou University.

For example, the team of Xijing Jiaotong University is from three universities, as well as Xihai University and Xijing University of Science and Technology.

The team at Huzhou University is similar.

This kind of temporary team of universities is here to learn, but it is also useful, they each allocate half of the workload of Working Group 7, and the final data analysis will be compared with the data results of Working Group 7.

If the data from both sides are consistent, the analysis results will be no problem.

If there is a disagreement, it is necessary to find out the problem of one of the parties, and in most cases, it must be a problem with the temporary patchwork of team data.

After Xue Wenzhuo and Dong Zhihui sat down, several people from the seventh group in the front row looked back, nodded towards Xue Wenzhuo, and some people who knew Dong Zhihui nodded.

Wang Hao was also looked at several times, and no one recognized him at first, until someone whispered something in front of him, and suddenly several people turned around together.

"Professor Wang Hao?" A professor in the front row asked.

Seeing Wang Hao nodded, the people next to him suddenly became much more enthusiastic.

Wang Hao and a few people greeted a few people, and the meeting was ready to start, he sat in his position, listening carefully to the content of the work assignment of the meeting, and it still felt very novel to participate in this kind of meeting.

During the meeting, Xue Wenzhuo also explained the work of the team, and said with some self-deprecation, "We are the marginal characters, and the seventh group in front is the main force." ”

"But we're mainly here to learn, and no one else has the opportunity yet."

Wang Hao doesn't care about the main force and substitutes, it is normal for two teams to do the same data content, otherwise there is only one team to do it, and it is difficult to find out if there is a mistake in the research.

If it can play a certain role, of course it is the best, and it doesn't matter if it doesn't work.

He's not a physicist anyway.

Wang Hao was concerned about the time, "How long will this analysis take to complete?" ”

Xue Wenzhuo said, "Roughly three to five days is fine, if the progress is slow, it will take a week." ”

This time is still acceptable.

Wang Hao continued to ask, "In other words, we can leave after we finish this experimental data analysis, right?" ”

"Yes."

Xue Wenzhuo nodded, "We mainly come here to participate in the experimental analysis work, so that others can also know how to do similar work, when it is best to have results, such as faster completion, such as consistent with the data of Working Group 7, this kind of performance is very good." ”

"Working Group VII, how long will it take to complete all the analysis?" Wang Hao asked curiously.

"They have twice as much data as we do, but it should be over in five days, right?" Xue Wenzhuo is also a little uncertain, but generally speaking, the main working group is very strong, and even if it is twice the data, it can be completed faster.

……

In the afternoon of the experiment, the work teams began to distribute work downward.

The Xijing Jiaotong University team was responsible for the upper half of the data of Area F, and a few people in the team participated in the work, and began to explain to others how to analyze the specific data and assign the work.

Some people are responsible for the analysis of big spots, some people are responsible for the removal of small data, and most of them are responsible for the analysis of ordinary data to determine what particles belong to, and calculate and record relevant detailed data.

He Yi also participated in an experimental analysis work, he is a professor at Xihai University, naturally focused on Wang Hao and Xiao Xinyu, and explained to them in detail the methods and conditions of analyzing data.

After Wang Hao listened to it, he also understood most of it, but he would definitely look at it when the specific analysis had to be done, and he asked with some confusion, "Can this kind of analysis of ordinary light points only be calculated manually?" I think some of them can be directly divided by a computer, but some of them need to be calculated manually. ”

"How else?" He Yi pursed his lips vigorously, "The difference between many particles is too small, and all kinds of situations are different, only manual calculation can ensure accuracy, anyway, until now, there is no way to complete the analysis of all ordinary light spots." ”

Wang Hao thought about it and nodded, but he still felt that the speed was too slow, and it was no wonder that a team of more than a dozen people would take several days.

He thought about it for a moment, and simply set up a mission to try—

[Task 2]

[R&D Project Name: Ordinary Spot Particle Analysis of F-Zone Data (Difficulty: D)] 】

[Inspiration value: 0.] 】

It's so easy!

Wang Hao was a little surprised when he saw the difficulty of R&D content, but it was normal to think about it carefully, and he already had an understanding of the work.

The current job is to distinguish particles based on experimental data, but distinguishing particles is only one of them, and it is necessary to calculate the various characteristics of the reaction.

However, the main difficulty in analyzing the data of ordinary light spots is to distinguish particles according to their characteristics.

As long as the properties of the particles can be determined, it will be easy to analyze other relevant data, but there are still some parts that need to be calculated manually, but because the properties of the particles can be determined directly, the workload will definitely be greatly reduced, and it is roughly estimated that it can be reduced by more than 80%.

"The research is worth it."

When some people have begun to devote themselves to work, Wang Hao did not start to analyze, but continued to ask questions and discuss his doubts.

He, He Yi, Xiao Xinyu, and another one in the group is Deng Xiaoying, a female professor in her 40s at Xijing Jiaotong University.

When Wang Hao kept asking questions and discussing, it would definitely affect the progress of the work, Deng Xiaoying said a little depressedly, "Professor Wang, can we analyze it first, and then study it carefully, you have all figured it out, and it will not help the current work." ”

Wang Hao explained, "I'm just working now. It is estimated that we will be busy for several days to do the data we have been distributing, so I want to find a good way to help the analysis be completed quickly. ”

"How else can there be such a good way?" Deng Xiaoying's eyes lit up when she heard this, she looked at the large amount of data displayed on the computer and felt very irritable, it would be great if there was a simple way.

He Yi was puzzled, "If you want to find a simple way, you can't find it in a day or two, right?" ”

"Not necessarily, I already have an idea."

Wang Hao said seriously, "Listen to me first, talk about your ideas......

"I'm going to design a program that can divide the properties of particles, and if I can do that, I'll do most of the work."

The others nodded.

Wang Hao said, "In fact, these data seem to be very complicated, and it is not difficult to really analyze, the main idea is to find ......."

He began to speak.

Wang Hao is very experienced in designing programs for data analysis, even if the initial inspiration value is '0', he still has a certain idea, in the process of explaining, he found that the inspiration value rises unusually fast.

The most direct manifestation is that there are a lot of ideas in my mind, some of which I didn't think of before, and some of which feel like a sudden flash of inspiration.

It's inspiration!

Unlike the effect of "The Gift of Teaching", "The Gift of Research" can increase the inspiration of others, and then sift through the correct feedback in their own minds.

This kind of inspiration is different from knowledge and thinking, but it feels very subtle, just like doing a math problem, and it is naturally very smooth to solve it step by step, but suddenly I can think of a formula to solve it, and I feel that I have found a shortcut.

In the process of explaining, Wang Hao not only had an unusually clear idea, but because of the influx of some inspiration, he felt that he was really a super genius, and he could think of a more subtle method when he thought of a problem.

It's a great feeling.

Wang Hao was intoxicated and kept talking, and when he reached the last step, he reacted and checked the next task.

[Task 2]

[Inspiration: 106.] 】

“！！”

"Enough inspiration!"

At this time, the other three people looked at Wang Hao in great surprise, because they had just heard a very targeted programming.

From start to finish, each step is very subtle, and at the end of the analysis, the conclusion can be directly analyzed.

They listened very carefully, but there were still some puzzles, especially the methods of 'taking shortcuts'.

But they can tell that there is no problem with the procedure.

So, what are you waiting for?

"Let's get started, let's do a program together, I don't think it will be difficult, right?"

"It should be."

"Wang Hao, come and assign work." He Yi couldn't wait.

The foursome were busy until nine o'clock in the evening, just eating a fast food delivered and typing code into the computer all the time.

The next morning, I continued to work hard for another hour, and finally debugged the newly designed program.

"Let's get started!"

Deng Xiaoying felt a little excited, she thought it was a boring job, but it turned out to be a design program, and it only took them a few hours to complete.

He Yi extracted the data content assigned by the group and entered it as an input file.

Subsequently, the program was officially launched.

This screening process is not very complicated, using only an ordinary computer, and each data analysis takes about a second, but it is certainly much faster than a human speed.

Even if some data doesn't require effort, just look at it to know what particles are, but the human response is certainly not as fast as the computer, and not all the data is obvious, and a lot of data is still carefully analyzed to know what particles are.

This is where the speed of computer analysis comes in.

After running for more than ten minutes, the program outputs a large amount of data, each of which corresponds to a particle, indicating what particle the data belongs to.

That's enough.

The four-person group immediately recorded and calculated other aspects of data according to the characteristics of the output particles, and the workload was reduced by more than 70% at once.

What used to be 10 hours a day and four to five days of work can now be done in just one day.

They also began to work patiently.

In fact, the ideas of several people are very simple, and they can rest after completing the work in hand.

Data analysis is a bit boring.

They're really here to learn, but it's enough to learn, and they don't need to spend a lot of time getting involved, because they don't specialize in this research.

When it comes to data analysis, the mathematician's advantage comes in.

As Xue Wenzhuo said, what the experimental team lacks is mathematicians.

Wang Hao's work efficiency is obviously much faster than the other three, some calculation things, especially when it comes to the calculation of equations, can be done directly easily, others have to think carefully, and occasionally encounter difficult ones at hand, and give up not to make records for the time being.

With the support of Wang Hao's super high work efficiency, by 4 o'clock in the afternoon, all the data analysis work had been completed.

He Yi couldn't wait to submit the data.

"Whew~~"

"It's finally done!"

"I'm so tired!"

The four of them stood up collectively and stretched out for a long time, and they couldn't help but bring the ease of completing the work.

When I walked out of the small workshop, I saw that everyone else was busy, and suddenly a sense of superiority arose.

He Yi looked at Wang Hao and asked hesitantly, "Do you want to help others?" It's all one team. ”

Deng Xiaoying also looked at it.

"Of course, but I'll wait until dinner, and I'll have to explain it now, it's so troublesome."

Wang Hao covered his stomach and complained, "The fast food at noon is really unpalatable, I haven't eaten a few bites, and my stomach is almost hungry." Eat today...... Grilled fish, to be spicy, grilled fish with rice, perfect match! ”

"Makes sense!"

"That's right, hurry up!"

"Don't worry about the others, I'm starving." A few people quickly walked out the door and took a taxi to a nearby shopping street, leaving the rest of the group completely behind.
