Chapter 278

Academician Yang came out of the laboratory and saw Zhang Changqing and Chen Peipei laughing at the laboratory entrance.

"Where is Little Xu?" He said in the morning that he would let his students take Xu Qingzhou to relax.

Experiments must be done, but work and rest must be combined.

He also saw Little Xu staring blankly at the background data today, staring at that Feynman diagram again and again.

Thinking of this, Academician Yang shook his head with a smile. Young people indeed have curiosity about things, even background events can be stared at for half a day.

He also glanced at it at the time.

All useless background information.

Xu Qingzhou shook his head and said: "Still want to focus on mathematics. As for physics, it's just an interest, occasionally participating a little."

Read! {

Next door, Shen Yuanjie felt incomparable emotion. Once upon a time, he could be said to have fought a bloody path out of thousands of troops, only then reporting to the teacher's graduate student.

Now? The teacher came to invite personally.

Xu Qingzhou shook his head. Because he stayed up until 3:00 AM last night and did calculations during the day, now he just wanted to go back and sleep.

The atmosphere of the meal was quite good.

"Alright~"

Academician Yang's mouth moved, but he didn't know how to describe Xu Qingzhou's modesty, could only say, "I have to take a look first."

Academician Chu paused and said in a deep voice: "So I want to ask, are you willing to apply for graduate student here with me?"

Xu Qingzhou returned to the hotel, finished dinner in a few bites, and continued to invest in calculations.

For example, the three of them also studied the improvement of the physical model of this experiment.

"Old Gu's meaning, in the field of number theory, he has nothing left to teach you."

September 18th, Sunday.

Before leaving, Xu Qingzhou thought of something and reminded with a smile.

The whole process is quite complex, involving perturbation theory methods of quantum field theory, drawing and calculation of Feynman diagrams, particle spin and color, etc.

When Xu Qingzhou entered the private room, he saw Shen Yuanjie accompanying an old man talking. The old man looked fifty or sixty, his temples were a bit white, but he was full of spirit, his gaze bright and piercing.

!.

Optimistically, there will be results in another week.

Xu Qingzhou nodded and said: "When I was screening background events for the Higgs boson, I noticed a fluctuation similar to the Higgs boson resonance peak appearing in the background events."

"Abby, heard you stumbled in front of the Xia Nation people this time?"

Everyone greeted simply and started ordering food.

Xu Qingzhou didn't worry about the correctness of this report; he had verified it several times himself.

Looking at the USB flash drive on the table, Academician Yang didn't react for a while, confirming: "You said, you verified the existence of the coupling between the Higgs boson and top quark pair through data?"

The month-long CMS experiment finally came to an end. According to convention, after the experiment ends, there will be a two-day report exchange meeting, and some scholars will arrive early.

Chu Jiangfeng, honorary professor of Jingda, absolutely counts as the Taishan Beidou of the Xia Nation mathematics community—topology, harmonic analysis, partial differential equations, combinatorial mathematics, analytic number theory, etc.

A true mathematical master.

"The calculation process is all in the report."

At the same time, Professor Baker was drinking with an old friend.

"Hi, don't be depressed. Your student Mia is a formidable genius, not inferior to Xu Qingzhou."

Hotel lobby.

"You guys go, I have to rest for a while."

Shen Yuanjie said with a smile: "The teacher has always been thinking about wanting to see Jingda's genius, and finally found an opportunity today."

Seeing Xu Qingzhou come out, Shen Yuanjie waved.

Next, the three chatted about mathematical problems. Although Academician Chu wasn't majoring in the physics field, he had dabbled in it and also participated in calculations for many physics experiments, still quite understanding of things in physics.

Xu Qingzhou said seriously: "Thank you, Academician Chu, I will consider it seriously." Shen Yuanjie said he would treat him to dinner and said Academician Chu was also there.

On the 10th, Xu Qingzhou, who should have been on rotation, replaced Shen Yuanjie to finish the data analysis, came out of the laboratory, and went straight toward the town next to the experimental base.

Can't compare, can't compare. However, with Xu Xu Shidi's talent, it seems it's also worth it.

"Let's go together, I even paid the deposit for the venue."

"This"

Using the method of quantum field theory to calculate, using the Lagrangian to describe the interaction term between Higgs boson and top quark.

Professor Baker said helplessly: "In the Xia Nation team, there is an extra kid who is good at mathematics. This young man has strong talent."

This was just a small episode. In the following time, Xu Qingzhou returned to being busy, immersed in complex calculations.

"Little Xu, sit, don't be restrained." The old man was very kind.

Xu Qingzhou roughly guessed Academician Chu's purpose on the way. Before he could speak, Academician Chu had already waved his hand, "No need to rush to give me an answer. You can wait until you have thought it through before making a decision."

So, Xu Qingzhou has been busy with this?

"You guys play outside, pay attention to safety yourselves."

Seeing Xu Qingzhou looked really tired, Zhang Changqing still nodded and said: "Alright, then you rest well."

"I have also always admired Academician Chu."

Next, need to use Feynman diagrams to calculate the amplitude of Higgs boson and top quark pair scattering.

Zhang Changqing said: "Returned to the hotel. Tomorrow Team Leader Shen will go pick up Academician Chu, Xu Xu Shidi will cover the shift."

Academician Yang fell into silence. It was just that Xu Qingzhou said it too easily, tried to study it, and verified an important theory in the Standard Model.

"Ah?"

On the last rotation day, Xu Qingzhou sent his research report to Academician Yang's desk.

Xu Qingzhou was quite grateful to Professor Gu Zhizhong. It was lucky to have such a teacher who thought for him.

Zhang Changqing was stunned for a moment. Originally wanted to ask why, but Xu Qingzhou had already entered the elevator. Was Xu Xu Shidi too tired and started talking nonsense?

Up to now, he was still between the decay width and branching ratio of the two particles, so that he could get the probability of Higgs boson and top quark decaying into different final states.

There were also scattering cross-sections, decay processes, etc.

After ordering, Chu Jiangfeng looked at Xu Qingzhou and asked: "You are about to graduate from undergraduate soon, right? I see you are quite attentive to physics. Do you plan to major in physics in the future?"

Academician Chu nodded and said with a smile: "This idea is good. Learn mathematics well, and doing physics will get twice the result with half the effort. A few days ago at a mathematics conference, I met Professor Gu, and he has great expectations for you."

"Little Xu, let me introduce you. This is my teacher, Academician Chu Jiangfeng."

So, it was Chu Jiangfeng who wanted to see him?

"I'm worried I'll die suddenly." Xu Qingzhou felt his senior brother's deposit would probably be lost.

"By the way, Wang Wang Shixiong Zhang, you guys had better turn on the phone ringtone."

"Right, Old Chu is coming over." Academician Yang also thought of this matter.

Professor Baker shrugged and said with a smile: "I'm not depressed. Although Xia Nation won a small advantage this time, in high-energy physics, the distance between us is still a Pacific Ocean away."

This time it really wasn't an excuse. In the graduate stage, he didn't plan to completely root himself in the number theory field, so following Academician Chu was a good choice.

"So I tried to study it and found that this resonance peak came from top quark pairs."

Zhang Changqing grabbed Xu Qingzhou: "Junior brother, finally found you. I made an appointment with a few people, let's go have a barbecue."

Xu Qingzhou greeted respectfully: "Academician Chu, hello."

"No problem."

Just at this moment, the phone rang.

The old friend was drinking, and heard Professor Baker's expression change, "What? Oh! How is this possible!... I'll be there right away!"

"What happened?"

"The kid we just talked about seems to have done an earth-shattering thing."
