Chapter 269

Regarding being hated, Xu Qingzhou was used to it.

Scientists are human, and humans have emotions and desires; they will always have their own selfishness, especially in the Xia Nation, where interpersonal relationships in departments are slightly complex, and many people spend more effort on power struggles than on experiments.

Being used to it doesn't mean one can tolerate it.

In the face of powerful strength, everything is floating clouds. For example, the person who once fought with him for the leadership of the laboratory ended up blowing himself up.

Seeing Xu Qingzhou silent, Zhang Changqing thought he was worried and comforted him: "Junior brother, don't worry about it. It's everyone's default that Jingda and the Academy of Sciences each have one quota. Professor Wang is just sour."

"When you come into contact with society more, you will find that such things are actually very normal."

"Thank you, Senior Brother, I understand." Xu Qingzhou nodded slightly.

The first step of work is to reconstruct the particle's trajectory based on data using matrix and vector operations.

Read! {

This involves a large amount of linear algebra knowledge, such as vector dot products, cross products, and matrix inversion. For Xu Qingzhou, this basically had no difficulty.

Although Shen Yuanjie is not weak in physics, he specializes in mathematics. As for Xu Qingzhou, it goes without saying; in everyone's mind, he had long been linked to mathematics.

"."

She and Guo Ziyang actually became a couple too.

Shen Yuanjie took a sip of tea and was a bit surprised: "Qingzhou has a girlfriend?"

In front of the whiteboard, three figures stood blankly; the three whiteboards were filled with complex calculations.

Xu Qingzhou paused, thought for a moment, and also said very seriously: "Even I envy myself."

The amplitudes of the boson and fermion are j(b)mv=i16π2kmkv－gmvk2)1e and j(f)mvkv－gmvk2)1e respectively.

"Team Leader Shen, the data is all here."

Various data, of course, also come from before. The most referential is the experiment in July 2014, where the experimental team used the h→di-gamma decay channel to measure the mass and production cross-section of the Higgs boson.

!.

"Yes."

Academician Yang and the others are responsible for data screening and plan design, concentrating their efforts on solving the background problems in the experimental process. Xu Qingzhou and Zhang Changqing follow the deputy team leader Shen Yuanjie and are responsible for the calculation content, processing the data sent over by Academician Yang and the others.

In the small conference room.

Xu Qingzhou and Zhang Changqing both shook their heads.

Xu Qingzhou invested all his time here into the calculations. There was no way around it—time was urgent, two teams were competing, and the other side was an old-fashioned powerful nation.

Zhang Changqing came in with the data.

Zhang Changqing slumped in his chair, rubbed his temples, and stood up again, saying: "Let's go, junior brother, let's go to the restroom."

She rested her chin on her hand, looking a bit dazed.

Shen Yuanjie continued: "Next, we need to fit the data and build a mathematical model. This model must be able to describe the expected signal shape and background distribution of the Higgs boson decaying into two photons."

Seeing that Xu Qingzhou had already started taking notes, Shen Yuanjie smiled gently: "Qingzhou, this is your first time participating in this kind of experiment. You might not have any clues at the beginning, which is very normal. Don't be under pressure."

"Of course there is, and it's our school's school beauty."

"Yes, my brain isn't even turning anymore."

There is also a signal model composed of multiple Gaussian functions: 【s(x; \mu_k，\sigma_k，a_k)=\sum_{k=1}^{n_{ext{sig}}}a_k\cdot\exp\left(-\frac】

"Yes, take care of yourself, goodbye."

Adding Zhang Changqing, an expert in experimental physics, was also to fill the shortcomings of Xu Qingzhou and the others.

These can all be considered as verification of the Standard Model.

Xu Qingzhou thought for a while and said: "This model needs to be based on parameterized functions."

"You go, I'm making a call." Xu Qingzhou shook his head. Looking at Song Yao who had hung up the phone, Ding Jiahui let out a breath and took Song Yao's arm: "You two finally finished talking."

Her sister was truly beautiful, especially at this moment, as her usual coldness dissipated and a faint smile hung on the corners of her mouth.

"That's right." Shen Yuanjie nodded with a smile. He was a bit worried at first that Xu Qingzhou wouldn't keep up, but he found that he seemed to have worried too much. "Okay, let's start."

"Is there any problem here?" Shen Yuanjie asked.

After the personnel arrived, Academician Yang continued the analysis just now, went through all the materials, and the tasks were also assigned.

As a result, they were now living together with Xu Qingzhou.

Researchers had already observed the diphoton channel, {\displaystylew^{+}w^{-}} channel, and {\displaystylezz} channel as early as 2013, confirming that the Higgs field can interact with bosons.

4 days passed in a flash.

No matter how busy he was, Xu Qingzhou had to report his situation to the school beauty Song, such as calling or sending some photos of the scenery he took during meals in the afternoon.

Zhang Changqing looked at Xu Qingzhou with some envy and said: "Academic success, and you have a girlfriend too. Junior brother, this is what you call the peak of life."

A year ago, Yaoyao was still swearing that she wouldn't date before graduating from university.

Things have changed.

In the small conference room, Xu Qingzhou planned to read the experimental materials carefully.

Shen Yuanjie shook his head and said helplessly: "Stuck. Let's rest for 20 minutes first and let the brain relax."

In Rongcheng, at the entrance of a milk tea shop, Ding Jiahui held a cup of milk tea and looked helplessly at the beautiful girl leaning on the railing talking on the phone.

Song Yao had been in the countryside visiting her grandparents for the past few days and only returned today to be dragged out shopping by Ding Jiahui. But as soon as they met, Song Yao received a call from Xu Qingzhou.

Shen Yuanjie is a man of action; he doesn't drag his feet in speaking or doing things. After receiving the data sent by Academician Yang and the others, he quickly took Xu Qingzhou and the other two to start working.

It's true; he had long heard that this young man was very powerful, and now he had really felt it. After building the model, it was necessary to define the objective function.

Thus, the Xia Nation team was effectively divided into two groups: the former was responsible for formulating corresponding plans, and the latter was responsible for processing data and verifying the data of the plans.

The two returned to the conference room.

At the same time, the experimental group also observed two other modes, the {\displaystyleb{\overline{b}}} channel and the {\displaystyleau^{+}au^{-}} channel, in 2014, confirming that the Higgs field can interact with fermions.

"Let's go, the meeting is about to start."

"Girlfriend?"

The plan design is based on the previous CMS experiments.

He thought that Xu Qingzhou could achieve his current accomplishments because he must have spent all his energy on his studies.

Xu Qingzhou nodded slightly. Although this deputy team leader works at the Institute of High Energy Physics of the Academy of Sciences, he also came from Jingda, and his teacher is Academician Chu Jiangfeng of Jingda.

"Yes, thank you, Team Leader Shen."

"Hoo~"

The progress of the Polignac conjecture slowed down temporarily.

The task for Xu Qingzhou and the others this time is to start from the diphoton channel.

"Okay."

"Xu Qingzhou was very busy yesterday and didn't receive my call." Song Yao explained.

"Understood, today is to compensate you. Yaoyao, you have also become a little woman."

Ding Jiahui truly felt that Song Yao had changed a lot; the cold school beauty Song of the past was gone forever.

The two girls carried their milk tea and went to the shopping mall next door together.
