Great Country Academician

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 hand has been analyzed.

"Thanks a lot."

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

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

Xu Chuan shook his head. It is a pity that he did not find clues of the Yuchuan coupling phenomenon between Higgs and the third-generation heavy quark from the experimental data this time.

But this is also impossible.

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

In scientific research experiments, falsification will be cast aside by everyone.

No matter how sophisticated the falsification is, there are still loopholes, and sooner or later someone will discover it. It is impossible for him to do such a thing.

Hearing this, Chen Zhengping smiled and said, "It's nothing, not all research can find something, it's normal."

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

Chen Zhengping was in a good state of mind, and he was not disturbed or discouraged.

He has been doing research for many years, and it doesn't matter to him whether he succeeds or fails once.

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

Everyone didn't find out, which means that there is indeed nothing in the data this time, and it can't be regarded as a failure.

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

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

"Let me see if I can discover something from these data."

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

He has already processed the data on the manuscript paper, and it is hopeless to find the Yukawa coupling phenomenon between Higgs and the third-generation heavy quark (top quark t and bottom quark b) from these data.

But it might be possible to find the ideal search channel for the Higgs boson's most likely decays from these data.

This is not a new path, and it is not that no one has tried it before, but basically ended in failure.

Because it is too difficult to reduce the appearance energy level of the target mathematically.

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

Maybe this is valuable for CERN, after all, it can reduce funding expenditure, but it is of little value for researchers who shrink the research area, the Nobel Prize will not be awarded to you for this job, it will only be awarded to propose the theory people.

Few people will do a job that is difficult but does not bring great value to researchers.

Anyway, the particle collider is right under your feet. If you don’t find something at one energy level, just go to the next energy level to search. They don't need to worry about the funding of the LHC, and there is no need to die on it.

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

Because theoretically, the Higgs particle is the origin of the mass of elementary particles, and it may also be the origin of the mass of dark matter.

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

Therefore, an in-depth study of the properties of the Higgs boson has 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.

After the restart of the LHC, this kind of research has not stopped.

Regrettably, up to now, CERN has only observed less than 30% of the Higgs boson decays predicted in the Standard Model.

Among them is the Yukawa coupling phenomenon observed in 2015 between the Higgs and the third-generation lepton (Taozi t).

But that's only part of what the Standard Model predicts.

The remaining possible decays remain elusive, and no one has been able to find traces from them.

The Yukawa coupling between Higgs and the third generation of heavy quarks (top quark t and bottom quark b) is a decay predicted by the Standard Model.

It can perform Tangchuan coupling with the third-generation heavy quark, endowing some particles with 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, CERN's collider LHC has not been able to find traces of its decay and coupling from collision experiments.

Currently observing this decay mode and measuring its rate is determined or determined by fermion mass generation through Yukawa interactions.

But in the collision experiment, all kinds of detection equipment, such as the ATLAS toroidal instrument experiment detector, can observe not only particle collision data, but also more background fluctuations, noisy signals, other signals, and so on.

These things occupy an absolute bulk of the overall collision data.

According to the supposed collision data, useful data only accounted for one in three million of these waste data.

To analyze useful data from such an exaggerated proportion, we have to mention CERN's supercomputer and global computing grid, as well as the computer code written by particle physicists to analyze these data.

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

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

Physicists and engineers at CERN have written tens of thousands of lines of code, with an average of more than 20,000 programs running each day, searching for unusual signals among millions of events.

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

Here, Google has established the world's largest intelligent analysis of cloud data, using the huge data generated by CERN every day to improve the algorithm.

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

It can be seen that sometimes, the one who kills you is not necessarily from your peers, but from a field that you can't imagine.

With the help of CERN's excellent program, Xu Chuan successfully completed the data processing in his hand after spending a few days.

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

The biggest advantage of the Daritz diagram is that it allows people to see at a glance the density distribution of physical events, the existence of resonance states, the mutual interference of resonance states, the angular distribution of final state particles, and other physical quantities.

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

After all, for him, finding useful information from the Daritz map is what he is best at.

But this time, he needs to analyze it from another angle.

Staring at the Dalitz diagram on the computer screen, Xu Chuan fell into deep thought.

From a physical point of view, he is not unfamiliar with these things, and can even be said to be very familiar with them, but when he habitually switched to a mathematical perspective to analyze them according to the previous thinking, 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. To analyze it mathematically, it was no less difficult than untying a ball of twine played by a cat. The end of the thread could not be found. , let alone hands.

On the other side, Qi Xishao, who was drinking hot water in a thermos, walked past Xu Chuan, and his eyes fell on the messy manuscript paper on the table and the Dalitz diagram on the display.

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

The Yukawa coupling experiments on the Higgs and the third-generation heavy quarks (top quark t and bottom quark b) have been basically completed. Indeed, no clues were found in this experiment, and Nantah University is now preparing to submit acceptance materials and apply for a report meeting.

At this point, it can be declared over, and the researchers can put down their work.

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

After all, he became famous when he was young, and he solved a world-class problem in both the mathematics and physics circles. This will be the first time he will face failure. If he can't bear this kind of blow, it is possible for him to be paranoid and want to find something from the data.

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

On the road of doing academics, failures are always more than successes, and bearing failures is also a necessary path.
