Chapter 277 Meeting the Fans' Requests Before I knew it, I already had 60 followers on Weibo. There are still 99+ private messages, most of which are from advertisers and weird fans, and some directly send him papers. After the last lesson, he doesn't read any papers at all. In the comment section, he also saw many people concerned about his progress on the Polignac conjecture. Some people complained that he was too arrogant and asked him to at least talk about his recent situation. Xu Qingzhou said that he felt a little wronged, and the reason he didn't say anything was that he felt he had no happiness to share with his fans and friends. but After thinking about it, he found the CMS work ID card he took for Song Yao from the photo album. Editor's message: I'm in France and everything is going well. [Sodium ion 1323]: I’ll go first, Master Xu is awesome! [Little Gu who never closes]: Oh my god, God Xu went to France to participate in the collider experiment? 【roay】: A liberal arts student, although I couldn’t understand it, I was deeply shocked. Xu Qingzhou was also shocked when he saw these comments popping up. It should be around four in the morning according to Xia Country time. Are you guys not sleeping? [Wang Shiba's Little Moon]: The Weibo post reveals a strong smell of bullying. [Laughing every day]: Mr. Xu, weren't you working on the Polignac conjecture? Why are you doing physics experiments?
[I love mathematics]: That’s right, we who study mathematics cannot be so idle. [Native Trisolaran]: What you said above is not correct. God Xu is very good at physics. Isn't it normal to study physics? [Boss Yu]: As expected of a university with the support of Peking University, he is not even in his twenties, yet he can participate in world-leading experiments. [Xiao Nai]: Stop being jealous, the people above. All shit is linked to age. The person’s ability is there for you to see. [The Man in Straw Sandals]: Although I admire Mr. Xu very much, I have to be honest. Mr. Xu must have used a backdoor this time. This is an experiment in the particle field. [Waiting for the Wind to Come]: After all, he is the son of Peking University. Of course, if there are any quotas, they will be given to his own people. It would be great if he could earn more capital for his students. Oh~ Quite lively. After sharing his itinerary with netizens and taking a quick look at the comments, Xu Qingzhou put away his phone and opened the data analysis report for that period. In the experiment, batches of protons accelerated at nearly the speed of light collide, creating a rain of particle fragments from a collider's absorber called a collimator. After passing through a series of complex instruments, it is converted into data and appears in front of researchers in a visualized form. The experimental results are very good. The measured mass, decay width, spin parity, etc. of the Higgs particle are consistent with the predictions of the Standard Model. This is also one of the significances of the experiment, to verify the correctness of the standard model and fill the gap in its understanding of the source of particle mass. For researchers like Xu Qingzhou, the happiest thing is probably exploring the basic laws of the material world. When you think about it this way, it’s no wonder that people who study physics always feel that they have grasped the truth. In fact, they do grasp the truth. The data report that Xu Qingzhou is opening now comes from the ATLAS experiment, which is also conducting Higgs particle inspections. The distribution of the two-photon events screened with constant mass shows that the events are concentrated around 125 GeV, but according to all other known physical processes, it is estimated that at most 6340 events can be contributed here. Next, the two-photon invariant mass spectra of the two experiments are presented. The computer was humming, and on the screen, CMSSW was processing data, filtering out background contributions and leaving only the Higgs particles. and many more. At this moment, Xu Qingzhou paused.
From the curve graph, it can be seen that there is a resonance peak similar to the Higgs boson in the filtered background. There is a problem. He threw the previous data into CMSSW again, and then stared at the screen closely. Unfortunately, no similar formants are seen. Or, an illusion? But it’s not scientific. I’ve abstained from sex for almost a month, how can I still have hallucinations? Xu Qingzhou began to doubt himself and tried it again with the data he had just used. Still no? Squinting his eyes, he rubbed his hands and picked up a piece of manuscript paper. 30 minutes passed. Xu Qingzhou stopped again. Based on the current calculations, it can be basically confirmed that the resonance peak just now seemed to be produced by the top quark. According to the theoretical speculation of the standard model, there is indeed coupling between particles, and particles are divided into fermions and bosons according to their spin. Bosons are constantly emitted and absorbed by fermions, which leads to interactions between fermions, that is, bosons are particles that transmit interactions. For example, in strong mutual coupling, protons and neutrons are coupled through strong interactions, and the stability of the nucleus is maintained by exchanging gluons. So, this is some kind of coupling between the Higgs and the top quark? Xu Qingzhou couldn't help but feel a little excited. The Higgs boson was discovered too late. After the discovery, the Hadron Collider was shut down and stopped between operation and maintenance. Therefore, everything about the Higgs particle remains theoretical. There is a lot to do. Xu Qingzhou took out another piece of manuscript paper and listed what needed to be done next. The data was screened for events that might contain the top quark. Try to reconstruct the decay process of the top quark. The project is huge, but fortunately it is just for my own entertainment and there is no time requirement. I can directly access the CMS experiment database and use existing experimental data. Just do it. Xu Qingzhou turned on the computer and accessed the database, intending to take a look at previous quark research data first. Since he decided to try to verify the existence of the coupling between the Higgs particle and the top quark, Xu Qingzhou's last bit of rest time was gone, which made him regain the feeling of doing life-threatening experiments again. During this period, he also received a call from Academician Ma of the Quantum Laboratory, saying that all tests on the quantum satellite had been completed and the results were very ideal. Next is the final test. In the busy life, another week has passed and it is time to take a break. On the afternoon of the 9th, Zhang Changqing found Xu Qingzhou right after he came out of the laboratory: "Junior brother, can you find a place to relax tonight?" "No, I have to cover for Team Leader Shen tomorrow and can't drink." Xu Qingzhou said helplessly. "Team Leader Shen?"
Xu Qingzhou smiled and nodded, saying, "Team Leader Shen's boss is here, he has to go pick him up." "Academician Chu is here? We should go pick him up." Zhang Changqing nodded, a little regretful, "Okay, now we have to go have fun on our own." Xu Qingzhou smiled and nodded, and went back to the hotel. Zhang Changqing and Chen Peipei were waiting for people at the laboratory door, preparing to go to Geneva together. Looking at Xu Qingzhou's back, Chen Peipei sighed and said, "Junior Brother Xu is so busy. I noticed that he was reading materials during his rest time." "I guess he's preparing his graduation thesis." "Hiss~ Junior Brother Xu is about to graduate?!" "Yes, it's normal that Beijing University is planning to let the juniors graduate early. Those undergraduates who have been crushed can finally be liberated. Just imagine if you were a senior and were crushed by the freshman, what a shame." Chen Peipei seemed to be hesitant to speak, as if not only her undergraduate degree, but she herself felt like she was being crushed into ashes. Maybe only an expert like Senior Brother Zhang can help. (End of this chapter)
