Chapter 279 Are you going back to your country? On this side, Academician Yang had already taken the USB drive to the office of Professor Collins, the head of CMS. Seeing the fatigue on Academician Yang's face, Professor Collins said, "Yang, seriously, you should relax." Academician Yang handed over the item in his hand and said, "Professor Collins, you should take a look at this first." "I'm curious about what could make you so anxious." Professor Collins took the USB drive, opened the only file in it, and looked at the contents, his expression gradually becoming serious. 10 minutes passed. "Incredible." Professor Collins exclaimed, "This was actually accomplished by a young man!" Academician Yang nodded slightly and said, "I took a rough look and there is no problem with the calculation." "It seems that our experiment will have another remarkable result this time." Professor Collins was somewhat excited. The funding given to each laboratory by the LHC headquarters was limited, and one more achievement meant more funding could be obtained. "Now, we have to organize people to verify the report immediately."
"That's right, that's right." On September 9, the CMS experiment ended and the two-day report meeting officially began. Inside the stepped lecture hall. The seats were already full, and most of the people here were scholars from various universities and research institutes. Seeing that the time was almost up, Professor Collins walked up to the podium and said, "Gentlemen and ladies, welcome to this meeting. First of all, we must thank the cooperative group that participated in the experiment with applause." "Here we see more exciting experimental results for the discovery of the Higgs particle." "The two-photon channel measured the mass of the Higgs particle and the ratio of the production cross section to theoretical predictions, and the results were consistent with the Standard Model within the error range." "." “But our achievements go beyond that.” After a pause, Professor Collins looked in the direction of Xu Qingzhou and continued, "Xu Qingzhou from the Xia Guo group analyzed the extracted top quark pairs and successfully verified the existence of the coupling between the Higgs particle and the top quark pair." "what?!" "Does the coupling between the Higgs particle and the top quark pair exist?" Except for the collaboration group and LHC staff, everyone else was stunned for a moment and then exclaimed. As for the position of Xia Guo Group, Zhang Changqing sighed heavily. From the moment he received the call from his boss, he understood why Xu Qingzhou asked him to turn up the volume of his phone. The other members of Xia Guo's group also had emotional expressions on their faces. "That's right, it verified the existence of the coupling between the Higgs particle and the top quark pair. Let's give a round of applause to this young man who created a miracle." Xu Qingzhou had a calm expression and nodded slightly. He had seen this kind of scene many times and was not nervous at all. After Professor Collins finished his opening remarks, it was time for the collaborative group's report. The first person to take the stage was of course Academician Yang, who mainly talked about the multivariate method of identifying photons in the experiment.
Professor Baker also shared his findings on the mass measurement of the Higgs particle, and other team members presented their statistical analysis and statistical models. In the first match in the afternoon, it was Xu Qingzhou's turn. "When doing background analysis, I found an interesting phenomenon." "We all know that the Higgs particle then decays into two photons, and the sum of the energies of these two photons will correspond to the mass of the Higgs boson," Xu said. "In the energy spectrum, there may be an obvious resonance peak near this energy sum." As he spoke, he felt a strange gaze, a very hot one, which went beyond the desire for knowledge. Following the direction of his gaze, he saw its owner. Xu Qingzhou couldn't help but pause, thinking that it would be better to return home earlier. Mia nodded, retracted her burning gaze, and there was only one sentence in her mind: Yes, that's right, this boy has excellent genes! Next, Xu Qingzhou explained in detail his calculation process, including the calculation of scattering amplitude and scattering cross section, as well as the use of advanced algorithms and techniques to suppress background noise and improve signal purity. Looking at Xu Qingzhou on the stage, Zhang Changqing sighed. Some time ago he was still comforting Junior Sister Chen, asking her not to be so stressed out, and now it was his turn. My junior brother is so awesome that it’s unscientific. After 40 minutes, the report ended and applause broke out in the auditorium. Xu Qingzhou smiled gently, but he didn't feel very proud. It was indeed luck that helped him figure this out. If he hadn't seen the resonance peak by chance, he probably wouldn't have tried to study it. There were no restrictions at the exchange meeting, and everyone could form teams freely. At 4 pm, after answering various questions, Xu Qingzhou finally got away and was able to rest in a corner. Just after sitting for a while, Professor Baker came over. "Mr. Xu, to be honest, you are one of the most talented young people I have ever met." "Thank you." Xu Qingzhou smiled. "If you like, I can provide you with a recommendation letter from the University of California, Berkeley. Sorry, this is my alma mater, so I put it first. Other schools, such as Princeton and MIT, are also acceptable." Professor Baker paused and said slowly: "As long as you are willing, we can help you solve the green card problem and even the nationality problem." Xu Qingzhou shook his head and said, "I'm sorry, Professor Baker, at this stage, I have no plans to study abroad." This is not surprising. Most countries in the world value talent, and green cards and nationality are the most basic conditions. "If you have other requests, feel free to ask. You know, compared to Xia Country, a person can fully display his talents in a freer environment." Professor Baker said unwillingly. "I'm sorry, I love where I live and have no intention of immigrating." Xu Qingzhou shook his head. "I still hope you will consider it seriously." Seeing Xu Qingzhou's firm attitude, Professor Baker had no choice but to leave as he had other things to do. Before leaving, he said, "Xu, if you change your mind, you can contact me by email." Academician Yang noticed the situation here, but he was analyzing data for other scholars just now. Now that he finally had the chance to come over, he smiled and joked, "Are you going back to China?" Xu Qingzhou was helpless: "If possible, I want to fly back now." "You kid, you are the talk of the LHC right now." Academician Yang smiled and said with emotion that Xu Qingzhou is only 19 years old and his future is limitless.
"If I didn't have too many students and too little energy, I would really like to ask you if you want to apply for my postgraduate study. However, if you want, you can study with Academician Lin." "Mr. Lin?" Xu Qingzhou was surprised. Academician Lin Jinpeng is one of the founders of the field of quantum information and communication and a great figure. Xu Qingzhou had sought advice from him before. "Well, I don't need to say much about Academician Lin's status in the quantum field. Many active physicists today are his students." If it were in the past, Xu Qingzhou would have agreed long ago, but now this kind of content has been brushed up in the previous life. Xu Qingzhou said: "Academician Yang, I haven't even written my graduation thesis yet." "You boy." Academician Yang smiled and didn't force it. He said, "Okay, think about it carefully. I see you've already bought a plane ticket for tomorrow. Don't you plan to have some fun here?" "No, go home early." On September 9, the CMS collaboration announced the success of the experiment. As the world's most powerful hadron collider, LHC's experiments naturally attract the attention of countless scientific researchers. Of course, in addition to the scientific community, media such as AFP are also paying attention to the experiment. After all, LHC, as a model of human collaborative scientific research, is the glory of Europe. In major reports, Xu Qingzhou once again became the focus of attention. 【19-year-old reporter at LHC】 [Shocked, this Xia countryman created a miracle! ] Weird titles pop up all the time. In India, a young man who had just worked late at night came out of the office. While taking a breath, he opened his mobile phone to read the messages sent by his friends. If Xu Qingzhou were here, he would definitely recognize that this man was the Indian guy he met in Cambridge last time. "This is Xu Qingzhou?" Their previous plan might theoretically have been able to prove the Polignac conjecture, but it was too complicated, at least not possible with current technology. Therefore, over the past few months, their team has been revising the plan and has achieved encouraging results. "Huh~ This time, the honor will definitely be ours!" The Indian guy took a deep breath and turned back to the office. At the same time, while the academic community and various gossip media were celebrating and marveling, Xu Qingzhou had already boarded the plane back home. (End of this chapter)
