Chapter 272: This time it's truly stable

At this moment, the lecture hall was exceptionally quiet. Some were surprised at the person asking the question, while others were thinking about the content of the question.

Mia flipped to the place Xu Xu Qingzhou mentioned, thought for a while, and said, "This is not a problem. From a common sense perspective, it can be solved through high-order perturbation theory and non-perturbative effect estimation."

Xu Xu Qingzhou asked with a smile, "So, you haven't substituted the data to calculate it?"

Mia nodded.

Xu Xu Qingzhou said: "I suggest you try to calculate it now. At the position of the 18th formula of the coefficient function of the renormalization group equation \lambda)\right】{\lambda=\lambda_0}=\beta{m_h here, introduce the renormalization scale parameter λ."

Mia was stunned for a moment and picked up the signature pen on the side.

The people off-stage weren't idle either. For example, the head of the American team, Professor Baker, had already started calculating as soon as Xu Xu Qingzhou raised this question.

It was roughly equivalent to a long-distance running competition. Originally, it was to test the level of the athletes, but now everyone's tracks were different—some long, some short.

Xu Xu Qingzhou had long been familiar with this plan. Seeing Senior Brother Zhang handling things with ease on stage, he felt relieved. He took out the draft paper for the Polignac conjecture from his bag and continued the calculations from 3 days ago.

Time passed in a tense atmosphere.

Having been in Switzerland for seven or eight days, he had basically been busy with the plan and hadn't had time to solve the previous bottleneck.

If there were no accidents, this time it was truly stable.

"Alright, the above is the Xia Nation team's plan regarding diphoton channel analysis. If anyone has any doubts, feel free to raise them."

Even Wang Wang Qiming's gaze toward Xu Xu Qingzhou softened a little. Although he was still unhappy with this kid, he had to say in his heart: "Well done!"

!.

Having problems didn't necessarily mean losing. After all, the Xia Nation hadn't even gone on stage to share their plan yet. Besides the question Xu Xu Qingzhou raised, their plan was still very excellent.

But now... one could only hope that the Xia Nation people's plan was overall a notch lower than theirs.

But now... renormalization group theory hadn't encountered this kind of problem when dealing with other particle physics issues.

Hoo~ taking a deep breath, he focused his attention again.

Chen Chen Peipei had a bitter face, looking at the formulas on the draft paper, sighing inwardly. She had managed to stand out among the many applicants from the Academy of Sciences, so she could be considered to have ability, but compared to this Xu Xu Shidi Xu, the pressure was huge.

Here, the numerical value had deviated!

"For the analysis of the Higgs particle's diphoton channel, our team is primarily based on a series of trigger conditions and screening criteria, in..."

11:00 AM Swiss time.

Except for him and Chen Chen Peipei, who found it a bit difficult to calculate, the professors of the Xia Nation team around them were basically all performing calculations.

"Alright, going now."

On this side, Academician Yang put down his pen and said slowly, "This part indeed has a problem, and it's not very easy to solve."

Consequently, the lecture hall fell into silence again. One could faintly hear the rustling sound of pen tips sliding across paper.

On the Xia Nation team's side, Zhang Zhang Changqing went on stage to prepare. 10 minutes flew by.

The Xia Nation team's plan was perfect; no flaws could be found.

The expert group had also finished calculating.

Someone in the lecture hall spoke: "Oh! Sure enough, after substituting the Yukawa coupling constant, the numerical fluctuation is very large. If this theory is used to calculate further, differences in Higgs particle properties will be obtained at different energy scales!" He had already verified this plan several times with his team, but it didn't contain the Yukawa coupling constant. Just as his student Mia said, this belonged to common sense and was a part that didn't need to waste time calculating.

Could there really be a problem?

Zhang Zhang Changqing expressed his thanks, ended the report, packed his things, and stepped down.

If such a problem were encountered during the experiment, it wouldn't be scary. As long as a little bit of time was spent, one would definitely be able to find corresponding tools to correct it.

【When m0=100gev, m^2h=(125ext{gev})^】

Next was a 10-minute break.

If the American team's plan had problems, wouldn't the Xia Nation team be stable?

Next door, Xu Xu Qingzhou tapped his fingertips lightly on the table, looking at Mia, who was calculating on the podium, with a very confident expression.

Like Mia, Zhang Zhang Changqing greeted everyone and got straight to the point: "Next, I will represent the members of the Xia Nation team to share our plan here."

Academician Yang reminded: "Alright, Little Zhang, hurry up and go prepare."

Forget it, calculate first.

The most uncomfortable thing was that he still didn't have any useful ideas. He could only peel the cocoon, go over the properties of harmonic series and basic laws again, hoping to find a breakthrough.

In the American team area, Professor Baker frowned. The previous complacency on his face completely disappeared, and he stared tightly at the draft paper in front of him.

After speaking, he packed his things and walked off the stage.

Professor Baker didn't speak. Ever since the young man on stage spoke halfway through, he knew he had lost.

Zhang Zhang Changqing lowered his head and calculated according to the steps Xu Xu Qingzhou mentioned, but got stuck at the position of the coefficient function. He was a bit helpless. He looked up and found his boss, Academician Yang, staring at the draft paper with a slightly furrowed brow.

"Junior brother, well done." Zhang Zhang Changqing talked to Xu Xu Qingzhou and said with great satisfaction: "These Americans, arrogant all day long. Hehe, now they're confused, right?"

Mia sighed. This plan was very rigorous, especially in terms of calculation. There was no redundancy and it was extremely smooth. Her gaze couldn't help but look at the young man burying his head in calculations in the corner.

Zhang Zhang Changqing felt a little excited.

Around them, the people of the Xia Nation team also had faint smiles on their faces. Their mood was more like a roller coaster.

Due to the change of Higgs particle properties with energy scale, the theory would face greater uncertainty when predicting the performance of the Higgs particle under different experimental conditions. On the podium, Mia also discovered this loophole. She first looked at Professor Baker. Seeing that her boss also had no way to solve it, she withdrew her gaze. Her face still had no expression, "Thank you, Mr. Xu, for the reminder. We will perfect this part later."

Zhang Zhang Changqing took a deep breath, feeling a little excited.

Professor Baker led the team to perform calculations on the spot and was also communicating with experts, hoping to find a good solution.

Was it because of him? The American team had no problems, and others also shook their heads. Thus, the scene repeated itself, and the question-and-answer session passed directly.

Zhang Zhang Changqing said on the podium, waiting for questions.

Next, the time belonged to the expert group to discuss which plan to use.

2 minutes passed. Professor Collins, the head of the CMS experiment, went on stage and announced the adoption of the Xia Nation team's plan. The official experiment would start on the morning of the 19th, which also meant that Xu Xu Qingzhou and the others had an extra day of vacation.

Zhang Zhang Changqing originally wanted to drag Xu Xu Qingzhou out to play, but the plan had passed, and there were still many procedures to go through, so the heavy responsibility fell on him.

The meeting ended. Xu Xu Qingzhou went straight back to the hotel, had a meal at the restaurant, and returned to his room to do calculations.
