Chapter 293 The more you fight, the happier I am Xu Qingzhou was ready, and Gu Zhizhong and others in the audience were also sitting upright. They have already read the paper, so they are looking forward to today's defense. The Higgs mechanism and the improvement of renormalization group theory. The former is based on the latest CMS experiment and is considered to be the most cutting-edge research data. As for the latter, to a certain extent, it is more valuable than the Higgs mechanism. It is already foreseeable that this paper will explode like a grenade in the fields of quantum field theory and particles. Wilson won the 1982 Nobel Prize in Physics for inventing the renormalization group, which shows the importance of this theory. Xu Qingzhou glanced around and saw that they were all familiar faces. He adjusted the PPT, glanced at School Beauty Song, and started talking. "Good morning, teachers. My defense topic today is the unification of strong and weak interactions of particles and the Higgs mechanism." "The four interactions between particles and their unification have always been major problems in physics" No small talk, straight to the point.
In the lecture hall, a special one-on-one defense was taking place. On the stage, the boy was talking eloquently, and below the stage, the teacher was listening attentively. In the corner of the classroom, Song Yao took two photos with her mobile phone, sent them to two family groups, and announced that Xu Qingzhou's defense had begun. It took Xu Qingzhou 20 minutes to finish talking about his paper, and then it was time for questions. "Page 29, point 5, you used Fourier transform. Let's talk about this," asked Academician Chu Jiangfeng. "The regularization I used in the previous article: [Zm]=[Z]=[Zλ]=0[Z_m]=[Z_\phi]=[Z_\l=Z_mm, \phi_0=Z_\phi^{1/2}" “When integrating ∫, we only consider those fields whose Fourier transforms satisfy k＞∧, f(t)=frac{1}{2\pi}\int_{-\infty}^{\inf”” Xu Qingzhou wrote the formula on the blackboard and said at the same time: "In other words, the field represented by the internal lines in the Feynman diagram should not have high-frequency fluctuations." After taking the photos and reporting her itinerary to her two pairs of parents who were far away in Chengdu, Song Yao began to listen carefully to Xu Qingzhou's defense. Although it was a completely unfamiliar area for her. Xu Qingzhou is so abnormal and under so much pressure. He should work harder. Although she felt stressed, Song Yao did not have any strange feelings. Xu Qingzhou is amazing. But he couldn't escape her violent suppression, right? On the podium, Xu Qingzhou had finished his explanation. "Well, I'm fine." Chu Jiangfeng nodded appreciatively. Sitting in the second row, Zhu Sitong was filled with emotion. An undergraduate student was defending his thesis, and four academicians and two great professors were participating. This lineup was almost unheard of in the history of Peking University. To round it off, if he had a student like this, wouldn’t he be pretty awesome too? "You have derived new formulas for the pan-quantum constant and energy in the Higgs mechanism. These are very interesting, with rigorous writing and clear logic." After making his comments, Academician Yang Bing smiled and asked, "My question is, do you believe that the interactions between particles can be unified?"
Academician Yang's question had little to do with the paper, but the others thought it was a good question. There was nothing they could do about it. The paper was so well done that even with a critical eye, they couldn't find any faults. Xu Qingzhou nodded and said, "Believe it. Physics requires imagination, even if it seems far away at the moment." Yang Bing sighed: "When I teach quantum field theory, I always like to write on the blackboard 'Ignorance is not a shame'. Every physical theory should have a valid range. If it exceeds this range, we know nothing about physics, which is not a shame." "Indeed, if this were not the case, no progress in physics would be possible." He paused, then added: "I'm done nagging. I don't have any problems on my end." Next, let’s turn to Academician Ma Zailiang. The old man smiled and said, "My problem is similar to Lao Yang's, and it has nothing to do with thesis defense." "Please tell me." "Are you willing to come to the Academy of Sciences for graduate studies? Don't worry, the salary is definitely not a problem and we can negotiate." Ma Zailiang asked with a smile. Zhao Shengwen is a straightforward person, as we can see from the fact that he could directly ask Gu Zhizhong for people. At this moment, he glared and said, "Old Ma, it's not good to poach people in front of us." Ma Zailiang said leisurely, "Xiao Xu needs more experimental opportunities now. In this regard, the Academy of Sciences is still quite advantageous." Chu Jiangfeng and Gu Zhizhong looked at each other, smiled faintly, and did not participate. They thought to themselves, you guys can fight it out. The more fiercely you fight, the happier I am. "Lao Ma, we at Peking University can also meet your scientific research needs," said Yang Bing. On the stage, Xu Qingzhou felt a little helpless. How did a good question-and-answer session turn into a fight for people? He was about to speak, but Chu Jiangfeng, who had been watching the show, spoke first, "Lao Ma, Lao Zhao, Xiao Xu's graduate student is studying here." This was finalized in mid-October. The lecture hall fell silent. Xu Qingzhou nodded and said with a smile: "I have already applied to be Academician Chu's graduate student." "Xiao Xu, don't you think about it again?" Ma Zailiang couldn't help it. Yang Bing also said: "That's right, Xiao Xu, I have never seen anyone like you who is born to be good at physics." Xu Qingzhou shook his head apologetically. Chu Jiangfeng glared and said, "Xiao Xu is already my student. If any of you try to poach him again, I will be angry." These old guys might have let it go just now, but now that they know this young guy is their student, they are openly trying to poach him. Ma Zailiang and Yang Bing coughed dryly and said nothing more. "Old Chu, you got a bargain." Academician Wang Lin, who had verified the twin prime conjecture together, said with some envy. Seeing that the topic had gone off track, Gu Zhizhong coughed lightly and said, "Okay, if there are no problems, I will declare the defense over." "No problem." “This paper is great, and I have no problem with it.”
After confirming with a few old friends, Gu Zhizhong nodded and said with a smile: "The defense passed. Xu Qingzhou, congratulations on completing your undergraduate studies at Peking University." "Thank you teachers." Xu Qingzhou took the graduation certificate and degree certificate from Gu Zhizhong and expressed his gratitude to the six predecessors. The defense ended just like that. After receiving their bachelor's gowns from their counselor Zhu Sitong, Xu Qingzhou and Song Yao said goodbye and prepared to take photos. After the defense was over, a few old men started chatting. "That little girl is from Kyoto University?" "Yes, from the School of Economics, a disciple of Professor Li Daiyue." "Tsk tsk, no wonder his aura is so similar to Professor Li's." Chu Jiangfeng smiled and said, "I have booked a table at the Wanhe Hotel and I'll treat everyone to a meal." "It's rare that Old Chu is not busy today." Academician Wang Lin was amazed. Ma Zailiang said sourly: "Of course I'm not busy. I just accepted such a good student." Fortunately, I have known for a long time that Xu Qingzhou wanted to study mathematics. Even though I am still a little unwilling now, thinking that it is a waste of talent for such a good physics seedling to study mathematics, there is nothing I can do. Gu Zhizhong is quite open-minded. Although everyone regarded Xu Qingzhou as his student, he was the only one who knew that he had not actually helped much in Xu Qingzhou's studies. He supports anything that is good for the boy's future. "We must give Old Chu a good beating today." "Yes, I need to drink something." In the end, the unwillingness of Yang Bing and others turned into revenge. (End of this chapter)
