Chapter 165 The perfect integration of mathematics and physics
In the Nuclear Research Center building, David Gross checks emails every day and processes emails that need to be responded to.
As the chairman of the board of directors, he can receive hundreds of emails every day, and sometimes it is normal to receive two to three hundred emails.
But most of the emails are useless or related to work arrangements, which are easy for him to deal with.
After processing an experimental application report, Gross clicked on the next email.
"Xu,?"
His eyes fell on the sender's name, making him stunned for a moment.
This name, if he remembered correctly, seemed to be that of the talented young man from China.
A few days ago, I talked with him about how to use mathematics to narrow down the optimal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks.
"Do you still have any doubts about this aspect?"
Gross thought and clicked on the email.
He has a very good impression of Xu Chuan. He is a real genius. If everything goes well, he may be able to further promote its development in a certain field of physics in the future.
In addition, the two have some relationship.
After all, he is Edward Witten's mentor, and Edward Witten is Xu Chuan's mentor. After all, in Chinese terms, he is the master. With this relationship, Gross is not stingy with himself
's guidance.
Clicking on the email, the title caught his eye.
[The optimal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks]
The title of the email made his brown and black penis shrink slightly.
"Is this calculated?"
Doubts arose in Gross's heart, and he couldn't believe it.
It takes a lot of time to find the breakthrough point of a problem, determine the idea, verify the idea, speculate on the process, and calculate the results.
But only for how many days?
If he remembered correctly, it seemed that it had been less than a week since he last communicated with the other party.
In one week, the calculation of the optimal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks can be completed.
This is incredible.
Or is it that this email sent to him is just a theory without final data calculation?
At least, Gross doesn't believe that anyone can start from finding a breakthrough to complete the final data calculation in such a short period of time.
Impatient, he continued to look down.
As the lines of text and data calculations came into view, Gross couldn't help but start to marvel.
Even if you haven't seen the results yet, these exquisite calculation processes are enough to open your eyes.
"Starting from the soft gluon resummation effect of transverse momentum distribution, going back to quantum chromodynamics, and then giving an energy level upper limit to the coupled decay of the Higgs particle through quark confinement..."
"It's incredible. It's such a clever way to use the string breaking function to complete the distribution of n particles. Mathematical methods can actually be applied to physics in this way."
Staring at the calculation process on the computer, David Gross muttered to himself.
As one of the founders of quantum chromodynamics, his mathematics is not bad. Although it cannot be compared with those top mathematicians who specialize in mathematics, it is at least much better than ordinary physicists. Otherwise, how could Edward Witten be successful in the field of mathematics?
He learned mathematics from his hands.
But right now, he was still amazed by Xu Chuan's calculations.
Not only those mathematical formulas and ideas, but also more cleverly, in this calculation process, mathematics and physics are almost perfectly combined.
Those unexpected mathematical methods are weirdly and cleverly integrated into physical theories, building a new bridge to communicate with mathematical physics.
This was what amazed him the most.

[.....The corresponding energy eigenvalue is ea=(n 1/2)a,h→bb-bar decay energy level is 128gev~131gev,h→bb(μvbf=3.0^ 1.7~-1.6)]
It took David Gross more than an hour to read this email.
The final answer was deeply imprinted in his mind at this moment, and even made him a little impulsive. He wanted to immediately start the LHC to conduct a collision experiment to verify whether the calculation data was correct.
Because the whole calculation process is so delicate.
At the desk, Gross took off his eyes and rubbed his aching eyes, then stood up and stretched his muscles.
For him, an old man in his seventies, sitting for more than an hour is not a pleasant thing.
But now he had gained enough mental pleasure from an email that the physical torture was nothing.
After briefly moving his body, Gross sat back at the table. This time, instead of continuing to work, he picked up his cell phone and made a call to Edward Witten in Princeton.
Soon, the call was connected.
"Hey, Witten, have you checked your mailbox?"
"Not in the past two days, what's wrong?"
On the other end of the phone, Professor Edward Witten's confused voice came over. Gross smiled and said, "I suggest you take a look. You may be surprised by what's inside."
After hanging up the phone, Gross sat back in front of the computer and controlled the mouse and keyboard to reply an email to Xu Chuan.
He needed Xu Chuan to submit an application form for the seminar and an application for the LHC's particle collision experiment.
Although he is the president of the council, he does not have much power over the use of LHC.
This is something that needs to be discussed by the board members together.
Of course, in this process, his words still have a certain weight.
As for arranging a report meeting, that's nothing, it can be done easily.
.......
After replying to Xu Chuan's email, Professor Gross waited for nearly an hour before receiving a call from Witten.
"I read the email and it was really surprising." Witten said with sigh.
This chapter is not over, please click on the next page to continue reading! "Using mathematical methods to calculate the optimal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks is really surprising, and even more surprising The amazing thing is, he actually did it."
In the office, David Gross smiled and said, "It seems you have a successor."
In the Institute for Advanced Study in Princeton, Witten said noncommittally: "Maybe, but now it seems that I should go there."
"Come on, the next collision experiment may be the time to witness a miracle."
"If we can successfully find the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks, maybe we can find more things through this."
David Gross smiled happily. If the young man's calculations were correct, then a change might be coming.
In addition to previous research, the focus, at least part of it, may be biased towards mathematical physics.
Using mathematics to determine the search pass of a brand-new particle can not only save a lot of money, but also is a perfect integration and development of mathematics and physics, which can bring a new path to high-energy physics and particle physics.

Hua Guo Office Area.
Leaders of scientific research teams from three universities, including Nanjing University, China University of Science and Technology, and Jiaotong University, gathered together to discuss the optimal search decay channel calculated by Xu Chuan for the Yukawa coupling of Higgs and third-generation heavy quarks.
As well as subsequent experimental data analysis and work arrangements.
For the three universities, Nanjing University, China University of Science and Technology, and Jiaotong University, they have participated in quite a lot of experimental work.
But this is the first time we have come together for the same project like this.
“The h→bb-bar decay energy level is 128gev~131gev, h→bb(μvbf=3.0^ 1.7~-1.6). It’s incredible. Who would have thought that the Yukawa coupling energy level data of the third generation heavy quark is actually close to the HIG What is the energy level of the Sri Lankan particle?”
"According to previous standard models and experience, we can almost unanimously believe that the Yukawa coupling energy level of the third generation heavy quark is above 150gev. The last search target was between 160gev~180gev."
In the office, Academician Cao Hongyuan, the leader of the team at the University of Science and Technology of China, looked at the paper in his hand with an exclamation of wonder.
If there are no problems with the data calculated by Xu Chuan this time, it has almost broken previous physicists’ predictions on the Yukawa coupling energy level of Higgs and third-generation heavy quarks.
Although this is also predicted by the Standard Model, the physics community has almost unanimously agreed that the Yukawa coupling energy level of the third generation heavy quarks should be higher.
Therefore, the search for this experiment has always been focused on high energy level regions.
No wonder they still haven’t discovered the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks after more than a year.
If we follow Xu Chuan's calculations and calculate the work efficiency, we may have to wait until 2018 or 2019 to discover the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks.
"It is indeed surprising, but what I care more about is the calculation method in this paper."
On the side, Academician Zhang Jie, the leader of the team from Jiaotong University, pushed the frame and continued: "Starting from quantum chromodynamics, we use the string breaking function to complete the distribution of n particles, and calculate the coupled decay of the Higgs particle to give an upper limit on the energy level.
....”
"This method can be said to perfectly combine mathematics and physics. Your ability in mathematics is really amazing and beyond imagination."
He said the last sentence while looking at Xu Chuan.
I have to say that what is shown in this paper is really surprising.
The ideal search decay channel that has not yet been verified can be left aside for now, but the combination of mathematical methods and physical theory is eye-catching.
He has been engaged in physics research for so many years, and has done some research in the fields of high-energy physics and laser fusion physics. He has dealt with many professors and researchers. But he has never seen anyone who can apply mathematical methods so exquisitely.
Come from the field of physics.
Maybe top physicists like Edward Witten can do it, but if you put his age at Xu Chuan's level, it can only be said that this one is unique.
Hearing Academician Zhang Jie's praise, Xu Chuan smiled shyly and said, "I still have a lot to learn, but this time I will only trouble a few teachers for the analysis of experimental data."
According to the instructions of Professor David Gross, he has submitted an application for the use of the Reporting Conference and the Large Strong Particle Collider (LHC).
The two applications have already met with the board of directors this morning, studied the papers and data he submitted, and determined to be approved, so this experiment has been confirmed.
All that's left is to wait for lhc to conduct experiments based on his calculated data.
However, the experiment was scheduled for ten days later.
For the LHC's collision experiment, ten days is not a long time, and the start-up of the Large Strong Particle Collider also requires preparations for maintenance and repairs.
It's just that he jumped in line this time, and I don't know which unlucky guy was squeezed out.
After all, the LHC's collision experiments have been arranged long ago. If he jumps in the queue temporarily, someone will definitely be squeezed out.
But Xu Chuan didn't care, this kind of thing was completely normal.
Academician Zhang Jie from Jiaotong University said with a smile: "This is not a trouble, we have to thank you for providing this opportunity."
After a pause, he continued: "Are you interested in becoming a professor at Jiaotong University after graduation? The salary and so on are all negotiable."
Before Xu Chuan could reply, Chen Zhengping couldn't help it anymore. He glared at Zhang Jie and said, "Don't even think about it."
On the side, Zhang Jie glanced sideways at Chen Zhengping and said, "Old Chen, you are being overbearing now. Student Xu Chuan is free to decide where he will go after graduation."
"Although NTU is his alma mater, no one stipulates that students from any school must return to their alma mater."
"And your NTU mathematics department is just like that..."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Before he finished speaking, Chen Zhengping responded: "What do you mean, you old guy? What do you mean, the mathematics department of Nanda is just like that? Nanda's mathematics department is just like that."
No matter how bad our mathematics department is, it is still better than yours at Jiaotong University!"
The two started to quarrel, while Cao Hongyuan from Hua University of Science and Technology on the side watched the fun with a smile and chimed in from time to time. They were all old friends anyway, so let's just quarrel.
As for Xu Chuan, he shrank back. It would be better for him to stay away from such a quarrel between elders.
.......
After returning to the hotel from the office area, Xu Chuan turned on the computer and saw that Professor Artur Avila's email had been returned.
"Dear Xu, I am very happy to receive your letter, but the content shocked me. I did not expect that there is such a person among the team members of the cooperation project. He has not communicated with me, and has never obtained my information.
I have used your ideas, theories and calculation data without permission."
"I regret that I allowed him to join our discussion so that something like this happened."
"I'm sorry that this matter has caused trouble to you. I will file a complaint with Peking University."
After reading Professor Avila's reply, Xu Chuan sighed softly.
Just as he expected, Professor Mo did not contact Artur Avila, and used his theories and calculation data without authorization and consent.
This already constitutes plagiarism.
However, what Xu Chuan didn't understand was why there were such stupid people.
Stupid and bad.
Needless to say, it's bad.
Stupid simply because the other party has no brains at all.
He was not the only one present at that time, there were four people present. Even if he and Hu Xingjian were not looked down upon, there was also Artur Avila, the Fields Medal winner.
Under such circumstances, he actually dared to use other people's ideas, theories, and even calculation processes and data without any prior knowledge.
Is this when others don’t exist?
If anyone raises a question, he will fall into the whirlpool of public opinion.
