Chapter 275 The Physics of “Science Fiction”
On the 19th, the experiment officially started.
Since 2013, CMS has basically been shut down for a long time, which can be regarded as a "consolidation" period. Researchers have maintained the accelerator components to help it operate at higher energy when it restarts in 2015.
It turns out this actually works.
After this restart, its operating energy has nearly doubled compared to before, allowing two proton beams to collide with an energy of 13 TeV (trillion electron volts).
Both CMS and ATLAS are conducting experiments to verify and complement each other's experimental results through joint measurements.
In fact, for Xu Qingzhou and others, the main task now is to receive detection data and then conduct corresponding analysis.
Xia Guo's group is responsible for providing the plan, LHC staff operate the instruments, and the American group assists.
Competition is competition, but when they cooperate, the two groups still get along very harmoniously.
In the conference room, Academician Yang and Professor Baker walked in with smiles and whispered.
After sitting down, Professor Baker glanced at Xu Qingzhou, who was bowing his head and calculating in the corner, and said with emotion: "Academician Yang, you have a very good young man in your team."
Academician Yang smiled and nodded: "Yes, his performance is amazing. In the future, he will definitely have a place in the physics community."
"I agree."
Professor Baker glanced in the direction of Xu Qingzhou again, his eyes darkened, and he looked away, "Academician Yang, it's your turn to speak."
Academician Yang had a smile on his face and nodded slightly. He had seen through his old rival. This old guy was thinking about poaching people, right?
In the conference room, Academician Yang began to assign tasks.
Xu Qingzhou was assigned to the data processing group. Together with Academician Yang, he was responsible for using the data collected by the detector to reconstruct the particle tracks and energy distribution in the collision event through algorithms, and also suppressed background noise and background contributions from other processes.
Academician Yang said: "The amount of data is huge, and we still need a manpower. Professor Baker, please recommend it."
Mia volunteered: "Professor Baker, let me do it."
Professor Baker smiled and nodded.
"Okay, the four of us will handle this part." Academician Yang nodded. As far as he knew, the data processing of the American group plan was done by the girl in front of him, and her ability was very outstanding.
Mia nodded slightly to Xu Qingzhou.
Xu Qingzhou smiled faintly and nodded in response, but he had a suspicion in his heart that this woman came with bad intentions.
Academician Yang and Professor Baker arranged work for others, including event reconstruction and photon identification, selection of two-photon candidate events, invariant mass spectrum analysis, etc.
A group usually consists of 3 to 5 people.
Have a work meeting and have a 10-minute break.
Zhang Changqing looked strange and whispered to Xu Qingzhou: "Junior brother, why do I think Mia treats you a little differently?"
"Illusion." Xu Qingzhou thought to himself that the other party already wanted to leave his father as his son, could it be the same?
"Really?"
Zhang Changqing shook his head and stopped thinking about it, "Junior brother, this is your first time participating in a high-energy physics experiment. Do you have any thoughts when you see these instruments?"
"Yes, human beings have a great ability to create things." Xu Qingzhou said.
Zhang Changqing nodded slightly, "Our collider in Xia Guo has also been put on the agenda. However, in terms of high-energy physics, Xia Guo still has a long way to go. It lacks talents in this area and has a weak foundation. It is too difficult."
"You will always get stronger." Xu Qingzhou smiled.
"I believe it too."
After the experiment was officially launched, Xu Qingzhou and the others were not so busy. They recorded data every day, conducted corresponding data analysis according to the plan, and conducted photon identification on triggered cases to ensure that the two high-energy signals recorded were indeed photons and not other particles.
Next, background suppression is achieved through accurate background simulation and data analysis techniques.
Xu Qingzhou is very busy, working in the laboratory, canteen, and hotel, but he is very motivated.
It is actually a very miraculous thing to allow various particles to achieve head-on collisions almost at the speed of light, creating hundreds of millions of "Big Bang" scenes.
In addition to particles, there is also dark matter and supersymmetry.
It sounds very sci-fi, but these have now become the main concepts of new physics. In the blink of an eye, two weeks passed.
Entering September, Xu Qingzhou's three-point and one-line life, Song Yao, Ding Jiahui and others returned to Kyoto, and classes have started.
Beijing University, in the classroom.
Zhang Qiong frowned and was looking at the projects that could be applied for. She sighed with some distress and turned to ask Song Yao who was reading: "Xiao Yao, do you have any plans to create a project of your own?"
If possible, she can come along and help with odd jobs.
In the sophomore year, after a certain amount of knowledge has been accumulated, everyone will start to choose to do practical work, that is, working on a project by themselves or working on a project with the teacher.
Song Yao stopped writing and shook her head, "Professor Li called yesterday and I have agreed to join her project."
"Professor Li Daiyue?!" Zhang Qiong exclaimed.
Teng Xiaojuan and Zhong Ruotong also looked over, a little surprised.
Song Yao nodded with no expression on her face, maintaining her image as a cold girl.
“That’s a national-level issue!”
Zhang Qiong was a little envious, "She called me personally. People's joys and sorrows are indeed different."
Zhong Ruotong recalled it and said: "Professor Li has always been very optimistic about Xiaoyao. Didn't he ask Xiaoyao last time if he wanted to apply for her graduate degree?"
"Professor Li. When I think of Professor Li's death gaze, I get goosebumps all over." Teng Xiaojuan touched her arm.
"Me too, Professor Li failed 18 people in macroeconomics."
"Horror."
Zhang Qiong looked at the girl next to her who was reading a book, and sighed in her heart, Xiaoyao was the one who read the most.
But when she thought about it carefully, she felt it was reasonable.
To have a double strong CP, of course you have to be strong in both.
11 a.m., 3rd floor, School of Economics.
When Song Yao went there, Professor Li Daiyue was alone in the office.
No wonder Xiaoqiong and the others are so scared.
In front of the computer, a middle-aged woman in her forties was smiling, with no expression on her face. Her eyes were fixed on the computer, and even the crow's feet at the corners of her eyes were full of dignity.
Dong~dong~
Song Yao knocked on the door.
"Come in."
Looking at the girl who came in, the coldness on Professor Li's face dissipated a little.
"Xiao Song, sit down."
"Hello, Professor Li."
Song Yao said hello, sat down, and said, "I have read the information you sent me. This is the analysis report."
The topic chaired by Li Daiyue is called "The Impact of Internet Finance on the Auditing of Xia Guo's Industrial Institutions" and comes from the Ministry of Industry and Information Technology of Xia Guo.
Li Daiyue took the USB flash drive from Song Yao's hand and clicked on the file.
When she gave Song Yao information three days ago, she also left two questions specifically about data drive and risk assessment.
After a while, Li Daiyue nodded with satisfaction. He answered both questions perfectly, with a concise process and clear logic and organization.
"Well, it's very good. You answer better than graduate students. But you are the only undergraduate in the department, so you won't feel any pressure, right?"
Song Yao shook her head and said: "On the contrary, I'm quite looking forward to it."
Li Daiyue admired Song Yao more and more. This girl's talent and temperament are the best choice. Unlike those little girls nowadays, they only know love and love, and they can't live without it.
She had long wanted to accept a disciple, and planned to let Song Yao train her in advance and train her as a successor.
