After analyzing the last bit of data in his hand, Xu Chuan straightened up and stretched, and then sent the completed analysis data to Chen Zhengping.

Up to now, the work assigned to him by Chen Zhengping has been completed, and all the experimental data analysis in his hands has been analyzed.

"Thank you for your hard work."

In the office, Chen Zhengping took over the analysis data from Xu Chuan and looked through it.

"It's nothing, it's just a pity that I couldn't find a clue to the coupling phenomenon between Higgs and the Yukawa of the third-generation heavy quark."

Xu Chuan shook his head, it was a pity that he did not find the clue of the coupling phenomenon between Higgs and Yukawa of the third-generation heavy quark from the experimental data this time.

But there's no way around it.

Even if he knew very well that the coupling phenomenon between Higgs and the third generation of heavy quarks in Yukawa definitely existed, it was impossible to fabricate a piece of data out of thin air.

In scientific research experiments, fraud is rejected by everyone.

No matter how sophisticated the fraud is, there are loopholes, and sooner or later it will be discovered, and it is impossible for him to do such a thing.

Hearing this, Chen Zhengping smiled and said, "It's nothing, not all studies can be found, it's normal." ”

"And with this experiment and data analysis, it will be much easier for us to apply for this research next time."

Chen Zhengping's mentality was very good, and he was not disturbed or discouraged.

He has been researching for years, and one success and one failure is nothing to him.

Of course, this is also related to the fact that the other two universities did not produce results in this experimental study.

Everyone didn't find out, which means that there is really nothing in the data this time, and it is not a failure.

........

After giving the analyzed data to Chen Zhengping, Xu Chuan sat back at the table.

The mentor's work has been completed, and the rest is his own arrangement.

"Let me see if I can find something out of this data."

Staring at the data on the table, Xu Chuan muttered to himself.

He had already processed the data on the paper, and it was no longer possible to find the Yukawa coupling phenomenon between Higgs and the third-generation heavy quarks (top quark t and bottom quark b).

But it may be possible to find the ideal search channel for the Higgs boson to decay most likely from this data.

This is not a new path, and it has not been tried before, but it has largely ended in failure.

Because it's so hard to mathematically narrow down the energy level of the target.

Moreover, the Standard Model has predicted the existence of such particles or phenomena, and simply narrowing down the collision level region does not make much sense to researchers.

Maybe it's valuable for you, because it reduces your expenses, but it's not valuable for researchers who shrink your research area, and the Nobel Prize won't be awarded to you for the job, it's only given to the person who came up with the theory.

It's a job that's difficult, but doesn't bring much value to researchers, that few people do.

Anyway, the particle collider is at your feet, and what is not found at one energy level, it is good to go to the next energy level to search. The LHC's funding doesn't need them to worry, and there is no need to worry about it.

......

After the discovery of the Higgs boson in 2012, CERN further began its research on the Higgs boson.

Theoretically, the Higgs particle is the origin of the mass of elementary particles, and possibly the origin of the mass of dark matter.

So it could be a 'window' to the world of dark matter.

Therefore, in-depth study of the properties of the Higgs boson is of far-reaching significance for revealing the nature of the new interaction force, understanding the mechanism of electroweak symmetry breaking, and the early evolution of the universe.

Since the resumption of LHC, this type of research has not stopped.

Unfortunately, less than 30% of the Higgs boson decay predicted in the Standard Model has been observed so far.

Among them is the Yukawa coupling phenomenon observed in 2015 between Higgs and the third generation of leptons (Taozi T).

But that's just part of the standard model predictions.

The remaining possible decay is still elusive, and no one can find traces from inside.

The Yukawa coupling of Higgs with the third-generation heavy quarks (top quark t and bottom quark b) is a kind of decay in the Standard Model prediction.

It can be coupled with the third-generation heavy quark to give a part of the particle mass.

And these particles may be the raw materials that make up common substances in our daily life, such as iron, copper, nickel, gold, silver and other metals.

But so far, the collider LHC has not been able to find traces of its decay and coupling from collision experiments.

Observing this decay pattern and measuring its rate is currently determined or uncertain by the Yukawa interaction, the mass generation of fermions is determined.

In the collision experiment, all kinds of detection equipment, such as the Atlas super-torus instrument experimental detector, can observe not only particle collision data, but also more background fluctuations, noisy signals, other signals and so on.

These things make up the absolute majority of the overall collision data.

Based on what we thought of as collision data, useful data accounted for only one of the three million in these waste figures.

To analyze useful data from such an exaggerated percentage, we have to mention supercomputers and global computing grids, as well as the computer code that particle physicists wrote to analyze this data.

When LHC restarts in 2015, doubling the collision rate will generate about 30 petabytes of data per year, which is almost equivalent to 1 gigabyte of data per second.

To analyze and process such large amounts of data, today's particle physicists spend most of their time writing computer code.

of physicists and engineers have written thousands of lines of code, with an average of more than 20,000 programs running every day, searching for unusual signals across millions of events.

These excellent programs are not only used for analyzing particle data, but also for big data analysis, data detection, and other work.

This is where Google builds the world's largest cloud-based data intelligence analysis, refining algorithms with the help of massive amounts of data that are born every day.

The world's best data analysis program and the most advanced information sharing program were born here.

It can be seen that sometimes, it is not necessarily your peers who kill you, but from a field that you can't even think of.

.......

With the help of excellent programs, it took Xu Chuan a few days to successfully complete the data processing in his hands.

The processed data passed through his hands and turned into a pair of Daritz diagrams.

The biggest advantage of the Darritz diagram is that it can make people see the density distribution of physical events at a glance, the existence of resonance states, the mutual interference of resonance states, and the angular distribution of particles in the final state.... and so on.

With this, the rest of the work is not very difficult.

After all, coming to him, finding useful information from the Daritz diagram is the best thing.

Only this time, he needs to analyze it from a different angle.

Staring at the dalitz diagram on the computer monitor, Xu Chuan fell into deep thought.

Physically, he was no stranger to these things, and he was even familiar with them, but when he habitually switched to analyzing them from a mathematical point of view according to the previous thoughts, he became a little confused.

He couldn't find the direction to start at the first time, the letters and numbers on the dalitz diagram were intertwined and complicated, and it was as difficult to analyze them mathematically as it was to unravel a ball of twine that had been played with by a cat, and the thread could not be found, let alone do it.

On the other side, Qi Xishao, who was holding a thermos cup and making a cup of hot water, walked past Xu Chuan, and his eyes fell on the messy manuscript paper on the table and the dalitz diagram on the display screen.

"Senior Brother Xu, are you still analyzing the data?" Looking at the familiar things on the table, Qi Xishao frowned slightly.

The Yukawa coupling experiment with Higgs and the third-generation heavy quarks (top quark t and bottom quark b) has been basically completed. It is true that no clues were found in this experiment, and now NTU has begun to prepare to submit acceptance materials and apply for a report meeting.

At this point, it's time to declare the end over, and researchers can put down their work.

But Xu Chuan was still analyzing the data, which made Qi Xishao a little worried, worried about whether this excellent junior brother had been hit.

After all, he became famous at a young age, and solved a world-class problem in both mathematics and physics, which will face failure for the first time, and it is impossible to withstand this kind of blow, and it is possible to be paranoid about finding something from the data.

Thinking of this, Qi Xishao was ready to enlighten Xu Chuan.

On the road of academics, there are always more failures than successes, and it is also the only way to endure failures.
