Chapter 166 The Perfect Fusion of Mathematics and Physics
In the CERN Nuclear Research Center building, David Gross checked his emails daily and processed the emails that needed to be replied.
As the chairman of the CERN Council, he could receive hundreds of emails every day, and it was normal to receive two or three hundred emails at most.
However, most of the emails were useless or related to work arrangements, which were easy for him to deal with.
After processing an experimental application report, Gross clicked on the next email.
"Xu, Chuan?"
His eyes fell on the sender's name, which made him stunned for a moment.
This name, if he remembered correctly, seemed to be the genius boy from China.
A few days ago, he discussed with him how to use mathematics to narrow down the most ideal search decay channel for the Yukawa coupling of the Higgs and the third generation of heavy quarks.
"Do you have any doubts about this?"
Gross thought and clicked on the email.
He had a good impression of Xu Chuan. This was a real genius. If everything went well, he might be able to further promote its development in a certain field of physics in the future.
In addition, the two had some relationship.
After all, he is Edward Witten's mentor, and Edward Witten is Xu Chuan's mentor. In this way, in Chinese terms, he is the master. With this relationship, Gross is not stingy with his advice.
Clicking on the email, the title came into his eyes.
[The most ideal search decay channel for Yukawa coupling of Higgs and third-generation heavy quarks]
The title of the email made his brown-black pupils shrink slightly.
"Is this, calculated?"
Gross felt a sense of doubt in his heart, and he couldn't believe it.
Finding a breakthrough in a problem, determining ideas, verifying ideas, speculating processes, and calculating results all take a lot of time.
But it's only been a few days?
If he remembered correctly, it seemed that it was less than a week since he last communicated with the other party.
In a week, the calculation of the most ideal search decay channel for Yukawa coupling of Higgs and third-generation heavy quarks can be completed.
This is incredible.
Or is this email sent to him just a theory without the final data calculation?
At least, Gross didn't believe that anyone could find a breakthrough and complete the final data calculation in such a short time.
He couldn't wait to read on.
As lines of text and data calculations came into view, Gross couldn't help but start to marvel in his heart.
Even if he hasn't seen the results yet, these exquisite calculation processes are enough to open his eyes.
"Starting from the soft gluon resummation effect of the 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."
"Incredible, it's a really clever method. Using 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 he can't compare with those top mathematicians who specialize in mathematics, he is at least much better than ordinary physicists. Otherwise, how could Edward Witten learn mathematical knowledge under him.
But at the moment, he was still amazed by Xu Chuan's calculations.
It's not just the mathematical formulas and ideas, but more cleverly, in this calculation process, mathematics and physics are almost perfectly combined.
Those unexpected mathematical methods are strangely and cleverly integrated into physical theories, building a new bridge for the communication of mathematical physics.
This is what amazed him the most.
[. The corresponding energy eigenvalue is Ea=(n+1/2)a, the H→bb-bar decay energy level is 128Gev~131Gev, H→bb (μvBF=3.0^+1.7~-1.6)]
It took more than an hour for David Gross to finish reading this email.
The final answer was deeply imprinted in his mind at this moment, and even made him a little impulsive, wanting to start the LHC collision experiment immediately to verify whether the calculated data is correct.
Because the whole calculation process is so exquisite.
At the desk, Gross took off his glasses and rubbed his dry eyes, and then stood up to stretch 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 spiritual pleasure from an email, and the physical torture was nothing.
After a simple exercise, Gross sat back at the table. This time he did not continue to work, but picked up his mobile phone and called Edward Witten in Princeton.
Soon, the call was connected.
"Hello, Witten, have you checked your email?"
"I haven't checked it in the past two days. What's wrong?"
Professor Edward Witten's puzzled voice came over the other end of the phone. Gross smiled and said, "I suggest you take a look. The content may surprise you."
After hanging up the phone, Gross sat back in front of the computer and controlled the mouse and keyboard to reply to Xu Chuan.
He needed Xu Chuan to submit an application form for a report meeting to CERN, as well as an application for the particle collision experiment of the LHC.
Although he is the chairman of the CERN Council, he does not have much power over the use of the LHC.
This is something that needs to be discussed by the members of the Council.
Of course, in this process, his words still have a certain weight.
As for arranging a report meeting, that's nothing, this thing 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 an exclamation.
"Using mathematical methods to calculate the most ideal decay channel for searching the Yukawa coupling between the Higgs and the third generation of heavy quarks is a surprising idea. What's more surprising is that he actually did it."
In the office, David Gross smiled and said, "It seems that you have a successor."
In the Institute for Advanced Study at Princeton, Witten said noncommittally, "Maybe, but now it seems that I should go to CERN."
"Come on, the next collision experiment may be the time to witness a miracle."
"If we can successfully find the Yukawa coupling phenomenon between the Higgs and the third generation of heavy quarks, maybe we can find more things through it."
David Gross smiled happily. If the boy's calculation is correct, CERN may usher in a change.
In addition to previous research, CERN may shift its focus, at least part of its focus, to mathematical physics.
Using mathematics to determine the search path for a new particle can not only save a lot of money for CERN, but also a perfect fusion of mathematics and physics, which can bring a new path to high-energy physics and particle physics.
CERN, China Office Area.
The leaders of the scientific research teams of Nanjing University, Huazhong University of Science and Technology, and Jiaotong University gathered together to communicate about the most ideal search decay channel for the Higgs and Yukawa coupling of the third-generation heavy quarks calculated by Xu Chuan.
And the subsequent experimental data analysis and work arrangements.
For Nanjing University, Huazhong University of Science and Technology, and Jiaotong University, the number of times they participated in CERN's experimental work is quite a lot.
But like now, it is the first time to gather together for the same project.
"The decay energy level of H→bb-bar is 128Gev~131Gev, H→bb (μvBF=3.0^+1.7~-1.6), incredible, who would have thought that the Yukawa coupling energy level data of the third-generation heavy quarks is actually close to the energy level of the Higgs particle?"
"According to the previous standard model and experience, we almost unanimously believed that the Yukawa coupling energy level of the third-generation heavy quarks was above 150Gev. The last search target was between 160Gev~180Gev."
In the office, the leader of Huazhong University of Science and Technology, Academician Cao Hongyuan, looked at the paper in his hand with an amazed expression.
If there is no problem with the data calculated by Xu Chuan this time, it almost breaks the previous physicists' prediction of the Yukawa coupling energy level of the Higgs and the third-generation heavy quarks.
Although this is also in the prediction of the standard model, the physics community almost unanimously believed that the Yukawa coupling energy level of the third-generation heavy quarks should be higher.
So all along, CERN's search for this experiment has always been mainly in the high-energy level area.
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 CERN's work efficiency, it may take 18 or 19 years to discover the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks.
"It's really surprising, but I'm more concerned about the calculation method in this paper."
On the side, Academician Zhang Jie, the leader of Jiaotong University, pushed his glasses and continued: "Starting from quantum chromodynamics, using string breaking functions to complete the distribution of n particles □, calculate the coupled decay of Higgs particles to give an energy level upper limit."
"This method can be said to be a perfect combination of mathematics and physics. Your ability in mathematics is really amazing and beyond imagination."
He said the last sentence while looking at Xu Chuan on the side.
I have to say that what is shown in this paper is really surprising.
The most ideal search decay channel that has not yet been verified can be left aside for the time being, but the combination of mathematical methods and physical theories in it is eye-catching.
He has been engaged in physics research for 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 apply mathematical methods so exquisitely in the field of physics.
Perhaps top physicists like Edward Witten can do it, but if you put Xu Chuan at this age, it can only be said that he is the only one.
Hearing the praise from Academician Zhang Jie, Xu Chuan smiled shyly and said, "I still have a lot to learn, but I'll trouble you with the experimental data analysis this time."
According to the instructions of Professor David Gross, he has submitted an application for the report meeting and the use of the Large Hadron Collider LHC.
These two applications have been held at the CERN Council this morning, and the papers and data he submitted have been studied and confirmed to be passed, so this experiment has been confirmed.
The rest is to wait for the LHC to conduct experiments according to his calculated data.
However, the time of the experiment is scheduled for ten days later.
Ten days is not a long time for the LHC collision experiment, and the startup of the Large Intense Particle Collider also requires maintenance and preparation.
It's just that he cut in line this time, and I don't know which unlucky guy was squeezed out.
After all, the LHC collision experiment had been arranged long ago. If he cut in line temporarily, someone would definitely be squeezed out.
But Xu Chuan didn't care. This kind of thing is normal at CERN.
Academician Zhang Jie of Jiaotong University said with a smile: "This is not a problem at all. 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? Salary and other things can be discussed."
Before Xu Chuan replied, Chen Zhengping on the side could not help it. He glared at Zhang Jie and said: "Don't even think about it."
On the side, Zhang Jie glanced at Chen Zhengping and said: "Old Chen, you are so overbearing. It is his freedom to go wherever Xu Chuan goes after graduation."
"Although Nanjing University is his alma mater, no one stipulates that students from a certain school must return to their alma mater."
"And your Department of Mathematics at Nanjing University is just so-so."
Before he finished speaking, Chen Zhengping retorted: "What do you mean, old man? What do you mean that Nanjing University's Department of Mathematics is just so-so? No matter how bad Nanjing University's Department of Mathematics is, it is better than your Jiaotong University!"
The two quarreled, and Cao Hongyuan of Huazhong University of Science and Technology on the side watched the fun with a smile, and occasionally intervened. Anyway, they are old friends, so they quarrel.
As for Xu Chuan, he shrank back. It would be better for him to stay away from such a quarrel between big men.
After returning to the hotel from the office area, Xu Chuan turned on the computer and Professor Artur Avila had already replied to his email.
"Dear Xu, I am very happy to receive your letter, but the content shocked me. I didn't expect that there would be such a person among the team members of the cooperative project. He did not communicate with me, and he used your ideas, theories and calculation data without my consent."
"I regret that I let him join our discussion, so that this happened."
"I am sorry that this matter has caused you trouble. I will file a complaint with Peking University."
After reading Professor Avila's reply, Xu Chuan sighed softly.
As he expected, Professor Mo did not contact Artur Avila, nor did he obtain authorization and consent to use his theories and calculation data without authorization.
This has constituted plagiarism.
However, what Xu Chuan didn't understand was why there would be such a stupid person.
Stupid and bad.
There is no need to say more about bad.
Stupidity is purely because the other party has no brains at all.
He was not the only one present at the time. There were four people present. Even if he and Hu Xingjian were not taken seriously, there was still Arthur Avila, the Fields Medal winner.
In this case, he dared to directly use other people's ideas and theories, even calculation processes and data without asking for permission.
Is this treating others as if they don't exist?
If anyone raised questions, he would be caught in the vortex of public opinion.
