Chapter 275 The Physics of Science Fiction
On the 19th, the experiment officially began.
Since 13, CMS has been basically 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 is restarted in 2015.
It turns out that this is indeed effective.
After this restart, its operating energy has increased by nearly twice as much as before, allowing two proton beams to collide with an energy of 13TeV (trillion electron volts).
Both CMS and ATLAS are conducting experiments, verifying and complementing each other's experimental results through joint measurements.
In fact, for Xu Qingzhou and his team, the main task now is to receive the test data and then conduct corresponding analysis.
The Xia Guo group was responsible for providing the plan, the LHC staff operated the instruments, and the American group assisted.
Competition is competition, but when it comes to cooperation, the two groups get along very well.
In the conference room, Academician Yang and Professor Baker walked in with smiles on their faces and talked in low voices.
After sitting down, Professor Baker glanced at Xu Qingzhou who was calculating in the corner, and said with emotion: "Academician Yang, there is 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 at Xu Qingzhou again, his eyes darkened, and he looked away, "Academician Yang, it's your turn to speak."
Academician Yang smiled and nodded slightly. He had seen through his old rival. This old guy was thinking about how to poach people, right?
In the conference room, Academician Yang began to assign tasks.
Xu Qingzhou was assigned to the data processing group, and 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, while also suppressing the contribution of background noise and background from other processes.
Academician Yang said: "The amount of data is huge, and we need another person. Professor Baker, please recommend someone."
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 for the American team's plan was done by the girl in front of him. Her abilities were outstanding.
Mia nodded slightly at Xu Qingzhou.
Xu Qingzhou smiled faintly and nodded in response, but he was wary in his heart. This woman had bad intentions.
Academician Yang and Professor Baker assigned work to other people, including event reconstruction and photon identification, two-photon candidate event selection, invariant mass spectrum analysis, etc.
A group generally consists of 3 to 5 people.
There is a 10-minute break during a work meeting.
Zhang Changqing looked strange, and whispered to Xu Qingzhou: "Junior brother, why do I feel that Mia treats you differently?"
"Illusion." Xu Qingzhou thought to himself that the other party already wanted to kill the father and keep the son, so how could it be the same.
"is it?"
Zhang Changqing shook his head and stopped thinking about it. "Junior brother, this is your first time participating in a high-energy physics experiment. What do you think of these instruments?"
"Yes, human beings have great creative abilities," said Xu Qingzhou.
Zhang Changqing nodded slightly, "Our Xia country's collider has also been put on the agenda. However, in terms of high-energy physics, Xia country still has a long way to go. We lack talents in this field and our weak foundation is too difficult."
"It will get stronger." Xu Qingzhou smiled.
"I believe too."
After the experiment was officially launched, Xu Qingzhou and his team were not so busy. Every day they recorded data, conducted corresponding data analysis according to the plan, and performed photon identification on the events after triggering to ensure that the two high-energy signals recorded were indeed photons and not other particles.
Next, background suppression is achieved through precise background simulation and data analysis techniques.
Xu Qingzhou is very busy. He goes between the laboratory, the cafeteria and the hotel, which is just a straight line between the three places, but he is quite motivated.
It is actually a magical thing to make various particles collide head-on at almost the speed of light, creating billions of "Big Bang" scenes.
In addition to particles, there is dark matter and supersymmetry.
It sounds very sci-fi, but these have now become the main concepts of the new physics. In a blink of an eye, two weeks have passed.
In September, Xu Qingzhou continued his life of going to and from work. Song Yao also returned to Kyoto with Ding Jiahui and the others, and school had already started.
Kyoto University, in the classroom.
Zhang Qiong frowned as he looked at the projects he could apply for. He sighed in annoyance and turned to ask Song Yao who was reading a book, "Xiaoyao, do you have any plans to start a project of your own?"
If possible, she can come along and help with chores.
By the sophomore year, when a certain amount of knowledge has been accumulated, everyone will start to choose to do practical work, that is, to tinker with a project by themselves or with a teacher's project.
Song Yao stopped writing and shook her head. "Professor Li called me yesterday, and I have agreed to join her project."
"Professor Li Daiyue?!" Zhang Qiong exclaimed.
Teng Xiaojuan and Zhong Ruotong also looked over, somewhat surprised.
Song Yao nodded with no expression on her face, maintaining her image of a cool girl.
“That’s a national-level topic!”
Zhang Qiong was a little envious. "She called me personally. People's joys and sorrows are indeed different."
Zhong Ruotong recalled and said, "Professor Li has always been optimistic about Xiaoyao. Last time, she asked Xiaoyao if she wanted to apply to be her graduate student."
"Professor Li. When I think of Professor Li's death gaze, I get goose bumps all over my body." Teng Xiaojuan touched her arm.
"Me too. Professor Li's macroeconomics class failed 18 people."
"fear."
Zhang Qiong looked at the girl next to her who was reading a book with her head down, and felt that Xiaoyao was the most enthusiastic one.
But when she thought about it carefully, she felt it made sense.
For a pair of strong couples, of course both of them have to be strong.
11:3 ., rd floor, School of Economics.
When Song Yao arrived, Professor Li Daiyue was the only one in the office.
No wonder Xiao Qiong and the others were so scared.
In front of the computer, a middle-aged woman in her forties was serious and expressionless, her eyes fixed on the computer. Even the crow's feet at the corners of her eyes were full of majesty.
Boom~boom~
Song Yao knocked on the door.
"Enter."
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 greeted him, and after sitting down, she said, "I have read the information you sent me. This is the analysis report."
The project led by Li Daiyue is called "The Impact of Internet Finance on the Audit of Industrial Institutions in Xia Country" and comes from the Ministry of Industry and Information Technology of Xia Country.
Li Daiyue took the USB drive from Song Yao and opened the file.
When she gave Song Yao the information three days ago, she also specifically left two questions, one about data-driven and one about 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, that's very good. Better than any graduate student. But you're the only undergraduate in the department. Don't you feel any pressure?"
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 character were both top-notch. Unlike those little girls nowadays, who only knew how to love and couldn't live without it.
She had long wanted to take in a disciple, and planned to let Song Yao come and train her in advance and cultivate her as her successor.
