Chapter 278 I tried to study it When Academician Yang came out of the laboratory, he saw Zhang Changqing and Chen Peipei chatting and laughing at the laboratory door. "Where is Xiao Xu?" He said in the morning that he would ask his students to take Xu Qingzhou to relax. Experiments need to be done, but work and rest are also needed. Today he also saw Xiao Xu staring at the background data, staring at the Feynman diagram again and again. Thinking of this, Academician Yang smiled and shook his head. It took a long time to look at the background events. Young people are indeed curious about everything. He also took a look at that time. It's all useless background information. Zhang Changqing said, "We are back to the hotel. Team Leader Shen will pick up Academician Chu tomorrow, and Junior Brother Xu will take over." "Yes, Old Chu is coming." Academician Yang also thought of this.
The month-long CMS experiment has finally come to an end. As usual, there will be a two-day report exchange meeting after the experiment, and some scholars will arrive early. "When you play outside, please be careful." "Okay~" Xu Qingzhou returned to the hotel, finished his dinner in a few seconds, and continued to devote himself to his calculations. The whole process is quite complicated, involving the perturbation theory method of quantum field theory, the drawing and calculation of Feynman diagrams, the spin and color of particles, and so on. The calculations were performed using quantum field theory methods, using the Lagrangian to describe the interaction between the Higgs particle and the top quark. Next, the amplitude of the scattering of the Higgs boson and the top quark pair needs to be calculated using Feynman diagrams. There are also scattering cross sections, decay processes, and so on. So far, he has been studying the decay width and branching ratio between the two particles in order to obtain the probability of the Higgs particle and the top quark decaying to different final states. If we are optimistic, the results will be out in another week. On the 10th, Xu Qingzhou, who was supposed to be on duty, finished the data analysis on behalf of Shen Yuanjie, left the laboratory, and went straight to the town next to the experimental base. Shen Yuanjie said he would treat him to a meal and that Academician Chu would also be there. So, it was Chu Jiangfeng who wanted to see me? When Xu Qingzhou entered the private room, he saw Shen Yuanjie talking to an old man. The old man looked to be in his fifties or sixties, with some gray hair on his temples, but he was full of energy and his eyes were bright. Seeing Xu Qingzhou coming out, Shen Yuanjie waved his hand. "Xiao Xu, let me introduce you. This is my teacher, Academician Chu Jiangfeng." Xu Qingzhou greeted respectfully: "Hello, Academician Chu." Chu Jiangfeng, honorary professor of Kyoto University, is definitely a leading figure in the mathematical community of China. He is proficient in topology, harmonic analysis, partial differential equations, combinatorial mathematics, analytic number theory, etc. A true master of mathematics.
"Xiao Xu, sit down, don't be restrained." The old man was very kind. Shen Yuanjie smiled and said, "Teacher has always said that he wants to meet the genius of Beijing University. Today, he finally found the opportunity." "I have always admired Academician Chu." Everyone exchanged brief greetings and started ordering food. After ordering, Chu Jiangfeng looked at Xu Qingzhou and asked, "You are about to graduate from college, right? I see that you are very interested in physics. Do you plan to major in physics in the future?" Xu Qingzhou shook his head and said, "I still want to focus on mathematics. As for physics, it's just my interest and I'll participate occasionally." Academician Chu nodded and said with a smile, "That's a good idea. If you are good at mathematics, you can get twice the result with half the effort in physics. I met Professor Gu at a mathematics conference a few days ago. He has high expectations for you." Xu Qingzhou is very grateful to Professor Gu Zhizhong. He feels lucky to have a teacher who cares about him so much. "What Lao Gu meant was that he no longer has anything to teach you in the field of number theory." Academician Chu paused and said in a deep voice: "So I want to ask, are you willing to apply to be my graduate student?" Xu Qingzhou roughly guessed Academician Chu's purpose on the way here. Before he could say anything, Academician Chu had already waved his hand and said, "Don't rush to give me an answer. You can make a decision after you have carefully considered it." Next door, Shen Yuanjie was filled with emotion. He had fought his way out of a huge enemy and was able to report as his teacher's graduate student. Now, the teacher comes to invite us personally. It can't be compared, it can't be compared. However, with Junior Brother Xu's talent, it seems worth it. Xu Qingzhou said seriously: "Thank you, Academician Chu, I will seriously consider it." This is really not an excuse. During his graduate studies, he did not intend to completely focus on the field of number theory, so following Academician Chu was a good choice. Next, the three of them talked about some mathematical problems. Although Academician Chu did not specialize in the field of physics, he had dabbled in it and had also participated in many calculations of physical experiments, so he still had a good understanding of physics. For example, the three also studied the improvement of the physical model of this experiment. The atmosphere of the meal was quite good. This was just a small episode. In the following time, Xu Qingzhou became busy again, immersed in complex calculations. October 9th, Sunday. On his last day off, Xu Qingzhou delivered his research report to Academician Yang's desk. Looking at the USB drive on the table, Academician Yang didn't react for a moment, and confirmed: "You said that you verified the existence of the coupling between the Higgs particle and the top quark pair through data?" Xu Qingzhou nodded and said, "When I was screening the background events of the Higgs boson, I noticed a fluctuation in the background events that was similar to the resonance peak of the Higgs boson." "So I tried to study it and found that this resonance peak came from the top quark pair." “The calculation process is all in the report.” Academician Yang fell silent. Xu Qingzhou just said it too easily. If he tried to study it, he would verify an important theory in the standard model. So, this is what Xu Qingzhou has been busy with?
Academician Yang moved his mouth, but he didn't know how to describe Xu Qingzhou's modesty, so he could only say, "I have to take a look first." "no problem." Xu Qingzhou was not worried about the accuracy of the report as he had verified it several times himself. Hotel Lobby. Zhang Changqing grabbed Xu Qingzhou and said, "Junior brother, I finally found you. I have invited a few people. Let's go for a barbecue." "You guys go ahead, I need to take a break." Xu Qingzhou shook his head. He had stayed up until 3 . last night and had been doing calculations during the day, so now he just wanted to go back to sleep. "Let's go together. I've even paid the deposit for the venue." "I'm worried that I might die suddenly." Xu Qingzhou felt that his senior brother's deposit would probably be wasted. "This" Noticing that Xu Qingzhou looked really tired, Zhang Changqing nodded and said, "Okay, then you should have a good rest." "By the way, Senior Brother Zhang, you'd better turn on the ringtone of your cell phone." Before leaving, Xu Qingzhou thought of something and reminded with a smile. "what?" Zhang Changqing was stunned for a moment. He wanted to ask why, but Xu Qingzhou had already entered the elevator. Junior Brother Xu must be too tired, as he started talking nonsense. Meanwhile, Professor Baker was drinking with an old friend. "Abby, I heard that you guys fell flat on your face in front of the Xia people this time?" Professor Baker said helplessly: "There is a young man who is good at mathematics in the Xia team. This young man is very talented." "Hey, don't be depressed. Your student Mia is an incredible genius, no worse than Xu Qingzhou." Professor Baker shrugged and said with a smile: "I am not depressed. Although Xiaguo has gained a small advantage this time, in terms of high-energy physics, the gap between us is still as big as the Pacific Ocean." Just then, the cell phone rang. The old friend was drinking when he heard Professor Baker's face change, "What? Oh! How is this possible! I'll be there right away!" "What happened?" "It seems that the little devil we were just talking about did something extraordinary." (End of this chapter)
