At the report podium of the work meeting, Wang Hao gave a report on the particle characteristics analysis program.
He mainly explains briefly the ideas of the program and each part of data analysis.
This report is not an overall analysis of the program, and the purpose is not to let everyone know how the program is designed. It is just to explain the design ideas of the program and some problems in its use, so it does not involve some difficult points to understand.
Most of the people at the meeting could understand. They understood the overall idea and had a general understanding of the program.
This is enough.
Wang Hao does not need to explain the details, because it is just a program, and he is not facing a group of programmers. The main purpose of his report is to let relevant personnel know how to use the program and what situations it is effective for.
After completing all the explanations, Wang Hao made a simple summary, "So this program is effective in analyzing particle characteristics, and the specific effect depends on the specific situation."
"We are analyzing the data of group F. If we switch to other groups, we need to make certain fine-tuning of the program. As long as we understand the structure of the entire program and do similar data analysis, we can use computer analysis to complete it."
After Wang Hao finished his last words, he bowed slightly to the audience and then walked off the stage.
The venue also burst into warm applause.
They not only applauded Wang Hao's report, but also believed that Wang Hao's participation in the experimental work made a great contribution.
This program analysis method will be very helpful for the initial data analysis work in the future, reducing the very complicated workload in the data analysis process.
After Wang Hao walked down the stand, several more people came on stage to make reports, and then the meeting was declared over.
During the rest of the meeting, Wang Hao also checked the task status.
【Task 2】
[Research project name: Analysis of CP destruction of positive and negative Corsi superons (difficulty: S).]
[Inspiration value: 14.]
"It's a bit less..."
Wang Hao frowned slightly when he saw the data, but after thinking about it carefully, he felt it was normal.
The difficulty level of the latest data analysis task is S level. Even if the explanation content is data analysis, it is not bad to get 14 inspiration points.
In addition, it is very important that he does not understand the spectrometer detection data. Without a basic understanding of the data, it is very difficult to improve inspiration.
After the meeting, Wang Hao, He Yi and others were ready to leave.
The Institute of High Energy is very enthusiastic about Wang Hao. Two academicians, Zhang Yifang and Tian Guilin, as well as several professors, took the initiative to come and give him a gift.
This was the first time Tian Guilin shook hands with Wang Hao. He came to see Wang Hao off and was called by Zhang Yifang, but in fact, thinking about it, there was no conflict between him and Wang Hao.
The two did not even speak formally, just because Wang Hao designed a program to help the Xijing Jiaotong University team and the Huzhou University team complete the data analysis work for the upper and lower parts of Area F, resulting in the data analysis report of the Seventh Working Group
Wasn't hired.
This issue also comes down to Wang Hao's excellent personal abilities, rather than any personal conflicts between him and the Seventh Working Group or Tian Guilin.
Tian Guilin thought it was nothing.
Wang Hao simply didn't know the situation at all, because he had never spoken to Tian Guilin, and he did not expect that the other party would be greatly affected by him.
The two still shook hands with a smile and exchanged greetings.
Then, a group of people slowly walked forward.
Zhang Yifang, Tian Guilin and Wang Hao were at the front, and they once again talked about the work of universal instrument detection.
Tian Guilin introduced a lot this time, and he also expressed his understanding of the universal instrument detection project, "The number of hyperons is still too small. If you want to measure the asymmetric signal of positive-negative Corsi hyperon decay, you must create
A large number of hyperons have been produced, but the scale of our experiment is still too small."
"Now we all have a sense of pressure and urgency. If foreign institutions complete the research ahead of schedule, our work will be completely meaningless."
This is where many people worry.
Scientific research is also competitive, especially if other institutions have achieved results in research in the same field, then all efforts of those doing research in the same direction will be meaningless.
There are several institutions in the world that conduct Corsi hyperon decay research, and Amerikan has two laboratories, both of which specialize in 'producing' Corsi hyperons.
If they were allowed to complete the study of Corsi hyperons first and discover the asymmetric signal of positive-anti-Corsi hyperons, that is, the 'CP violation' of Corsi hyperons, the spectrometer detection project would be meaningless.
Their efforts of more than ten years will be in vain.
When the topic came to this point, many people fell silent.
Wang Hao smiled and said, "Academician Tian, ​​there is no need to be so pessimistic. Didn't foreign institutions say that they can create a thousand times more Corsi hyperons? But didn't they also fail to measure it? To a certain extent, it may mean that they want to increase the number of superons by increasing the number of superons.
It is not feasible to measure CP damage based on the number of pieces."
When he said this, others felt much more relaxed.
Zhang Yifang asked, "Professor Wang, from your understanding, why can't we detect the asymmetric signal of the positive-negative Corsi hyperon decay? Is there a possibility? I just said it is possible..."
“The theory is wrong?”
As soon as Zhang Yifang's words came out, the others fell silent again.
The research in theoretical physics is like this. Even if some theories are recognized by the whole world, they may not be correct.
Nowadays, a large number of physics institutions are conducting research around the Standard Model of Particles, but no one dares to say that the Standard Model of Particles is correct.
Even for those phenomena that have been discovered, because they are microscopic phenomena, only some signals can be detected, and theory is the analysis and explanation of signals and data.
Are these analysis and explanations necessarily correct?
Just like the well-known string theory in theoretical physics, many top mathematicians and physicists have conducted research around string theory. The most famous among them is Princeton University professor and Fields winner Edward Witten.
.
Edward Witten has been studying string theory throughout his life, and expanded it into superstring theory that explains multi-dimensional space, and a more complete X theory.
Even the Fields obtained by Edward Witten was based on the mathematical logic shaped in the process of perfecting string theory, and was a by-product of the study of string theory.
If one day string theory is proven wrong, it means that Edward Witten has been doing wrong research his entire life.
That would definitely be a sad story.
Wang Hao thought for a while and said firmly, "I dare not say that the specific physical theory is completely correct, but I think that there is indeed an asymmetry in the decay process of the forward-anti-Corsi hyperon."
His words were very firm and even surprising, because he is a pure mathematician, not a theoretical physicist.
Others also felt very good after hearing it, as if they were being recognized for their own work.
Thinking that I was engaged in spectrometer detection research, it turned out that no mathematician had firm confidence in supporting the basic theory of spectrometer detection, and I immediately started to reflect on myself.
Of course they don't know that Wang Hao has established a research and development task. As long as the task can be established, it means that the foundation is good.
I can’t say whether the general theoretical direction is correct, but the asymmetry problem of forward-anti-Corsi hyperon decay definitely exists, and what the asymmetry specifically means needs to be explained by physicists.
Several people continued to talk about the asymmetry problem of Corsi hyperon decay.
Wang Hao still had something he didn't understand, so he asked, "Is it not detectable now because in baryon decay, the weak reaction signal will be masked by the strong reaction?"
"This is the main reason, but it is not necessarily true. If the theory is correct, it also has something to do with the detection accuracy and analysis methods." Zhang Yifang explained.
At this time, Wang Hao was suddenly stunned.
When he just asked the question, he suddenly had a flash of inspiration in his mind. He recalled it carefully and it was said that 'the action of a force annihilated the CP signal'.
What's the meaning?
Wang Hao knew that "The Gift of Scientific Research" was at work, but he still didn't quite understand the content that appeared in his mind, so he simply asked, "Is there a possibility that there is a force that annihilates the CP signal?
?”
In an instant, more information is integrated into the mind.
Wang Hao suddenly understood and was shocked by the system prompt.
[Task 2, inspiration value +29.]
+29?
Is it really a force? And it is directly related to the data analysis of hyperon decay asymmetry?
Behind the crowd.
A doctoral student was following the crowd and was surprised when he heard Wang Hao's question. He thought to himself, "I was just wondering if the universe rejects positive particles. Even if there is a CP signal, it will be annihilated."
…”
"Professor Wang actually thinks the same as me?"
