Research starts with PhD students

Chapter 88 Meeting Report, Zhang Shuo: I found the connection between the two!

"Tie 'total energy loss' and 'deviation' together?"

“The two must be connected!”

"Energy is conserved. The source of the force field chaos is also energy..."

After careful consideration, Zhang Shuo immediately created a related task:

【Task 2】

[Research project name: Exploring the relationship between energy loss and deviation in particle collision experiments (difficulty assessment: D).]

【Progress: 0.352%.】

(The task can be canceled. Currently, the number of scientific research coins required to cancel the task is 0.)
(The remaining progress requires 10 scientific research coins.)
"D-class?"

He felt a little surprised, but it was normal when he thought about it carefully.

The experimental data and deviation analysis results are already there. We just need to analyze the relationship between the two from the experimental data, which is not difficult.

The most difficult part of this research is being able to 'think of it', but he has already thought of it.

At the same time, he is also very interested in research.

In the past, there was no research on the relationship between energy loss and deviation in particle collision experiments.

Perhaps it is because the research in the physics community in the previous life has progressed to the stage of "theoretical verification", and particle collision experiments clearly show the existence of unknown physical phenomena.

Several theories, including the 'Source Point Theory', are based on this unknown phenomenon.

The emergence of 'deviation' is the result of lengthy experimental research. In most cases, the problem of total energy loss is an ignored data, because when the direction is truly clear, there is already accurate electromagnetic energy measurement data.

When electromagnetic energy loss is linked to the chaotic force field problem, the deviation, total energy loss, etc. are bound to be inaccurate, and data that are invalid for theoretical and experimental verification will be directly ignored.

After returning to the hotel, Zhang Shuo went to have dinner first, then went into his room and began to look at the data carefully.

This study involves two data, one of which is deviation.

The Computing Center of the Institute of High Energy Physics has completed numerical calculations of the deviations of several experiments. Subsequent calculations are still in progress, and more than a dozen values ​​have been made public.

More than a dozen values ​​correspond to more than a dozen experiments.

Each experiment has detailed data, and a 'total energy loss' can be calculated based on the data.

'Total energy loss' involves many factors, including initial energy, photon energy, kinetic energy of escaping particles, and the energy of various particles measured, etc.

There will definitely be deviations when calculating so much data together.

This is also the reason why "energy loss" is not taken seriously. Even if a detailed measurement and analysis is carried out, there will definitely be differences from the initial energy.

However, the difference rate is within the fixed ratio range.

After Zhang Shuo conducted a series of calculations, he quickly found the key point - the total energy intensity, which involves the number of protons, the impact speed, the influence of external electromagnetic field interference, etc.

The ratio of total energy loss to total energy intensity, that is, the 'energy loss ratio', has a direct relationship with the degree of deviation.

The two are positively correlated.

The two are not directly positive, and will also be affected by the strength of the magnetic field, and involve a coefficient problem.

Zhang Shuo continued to do calculations and research.

In order to strive for accuracy and reduce deviation, the 'coefficient' must be calculated more accurately.

……

The next morning, when Cui Kaiwen came to see Zhang Shuo, he saw a pile of calculation papers on the table.

Zhang Shuo went to bed in the early morning. He rubbed his eyes blearily and said, "I won't go in the morning. I still need to verify the data."

“Are you doing research?”

Cui Kaiwen was a little confused, but he didn't ask any more questions and left.

When I saw Zhang Shuo again, it was already afternoon in Lecture Hall No. 1. Cui Kevin, Bao Hexing and others had reserved seats for Zhang Shuo, and they sat in an entire row of middle seats.

In the front were people from the Physics Center, including Tan Zhiming and Gao Hongli. Liao Zhenyu and Yu Fei were also sitting in the back row with Zhang Shuo and others.

When Zhang Shuo sat down, he had a smile on his face.

Cui Kaiwen felt a little strange and couldn't help asking, "What good thing happened?"

"You'll know when the report comes."

Zhang Shuo said with a smile, he was indeed very happy, it was no big deal to complete a D-level research.

The key is - breakthrough!

In his previous life, there was no research on the relationship between energy loss and deviation in the field of high-energy physics, but now he has completed the research that was not done in his previous life.

The study is small, but has great significance.

He couldn't help but ponder, "If small research can lead to breakthroughs, then large research can also lead to breakthroughs."

"Research does not necessarily follow the direction of the previous life. The theory and experimental verification of the 'origin theory' may all lead to breakthroughs..."

If we follow the research direction of our previous life, then in the end we will definitely have to conduct the "explosion" experiment.

But is that necessarily true?
Zhang Shuo is very fascinated by the "source point theory", but he dare not say that the theory and verification direction are correct, otherwise the explosion accident would not have happened.

The breakthrough in this small research made him feel that his horizons had broadened a lot, as if he had broken through the shackles of previous life theories and experiments and was moving towards a broader future.

This is the last day of conference presentations.

A summary closing meeting will be held tomorrow morning, attended by high energy physics institution teams, conference organizers, and specially invited scholars and teams.

Many scholars have already left early, and some have not left yet, so they are all gathered in Conference Room No. 1.

There are a lot more people in the afternoon than in the morning.

This was mainly due to the circulating "rumor" that the Computing Center of the Institute of High Energy Physics had discovered a new physical phenomenon.

Many people come to the conference just to listen to the results report of the computing center.

The afternoon report starts at one o'clock.

The first to take the stage were the nuclear organization's basic experiment team, and the basic experiment was the particle collision experiment.

Many studies are based on particle collision experiments, including CP violation research and research by various CMS collaboration groups.

At this time, the order in the venue was not very good.

Because what he did on the stage was just a work report, and he talked about a lot of issues related to technology upgrades, which sounded very boring.

Most people don't care, and many people just chat.

The same is true for the people from the Institute of High Energy Physics.

Gao Hongli reluctantly listened twice to understand again the difference in the intensity of the experiments of both sides.

Tan Zhiming, who finally came out to take a breath, simply turned his head and asked Cui Kaiwen, "I heard that your computing center is going to release the results of the deviation analysis and confirm that there are unknown physical phenomena in it?"

"Shouldn't the Physics Center be notified of this kind of analysis results first?" His tone was somewhat questioning. Bao Hexing felt uncomfortable and immediately asked back, "Academician Tan, don't you know the results?"

"We have uploaded the results to the platform a long time ago. Anyone can see it. In addition, we discovered the particle fault phenomenon in the first analysis, but you said it was the air particles that were blocking it."

“We see it differently.”

"We think it's an unknown physical phenomenon, so we came to the conference to publish it."

Tan Zhiming was choked and couldn't speak for a long time.

The so-called "air particle obstruction" was his judgment. As a result, particle fault phenomena appeared several times in the analysis of dozens of experimental data.

The 'air particle obstruction' simply does not hold true.

They did not continue with follow-up research and analysis, mainly because they felt that the analysis would not be able to produce any results.

This is what happened, but Tan Zhiming was still very angry. He felt that Bao Hexing was very rude and had no respect for others at all.

He turned his head away and sulked.

On the other side, Yu Fei was chatting quietly with Zhang Shuo, talking about the algorithm that Zhang Shuo and Agostini were researching, and asked in detail about the "fluctuation" problem.

"In other words, there may be baryon cp signals in the fluctuating area?"

"Which specific region fluctuates is related to factors such as the number of hyperons and decay time... There are too many factors, so we can't do experiments based on the results of algorithm detection."

"If we are conducting research on signal conversion methods, can we also use the mirror effect to measure the anti-Corsi hyperon signal in detail?"

Yu Fei asked several professional questions.

He is an associate director-level researcher at the Center for Physics and one of the leaders of the CP group. He has been engaged in CP violation research for more than five years.

In the past five years, the CP group has had almost no results to speak of. They just kept conducting experiments, collecting data, analyzing data, and then it was over.

He was also very depressed that the signal conversion method of the hyperon decay experiment was proven to be ineffective, but he also had some expectations in his heart, because "the signal conversion method is ineffective" does not mean that there is no prospect for the research on baryon CP destruction signals.

The CP group will definitely be greatly affected, but it will not be completely denied. If a new direction can be found, perhaps there will be many results in the future, or even the discovery of baryon CP destruction signals?
This is so attractive.

As the two were talking, the Nuclear Organization Basic Experiment Team had already completed the report.

The person who chaired the meeting announced the next report content--
"Institute of High Energy Physics, Computing Center, Zhang Shuo, "Bias Value and Particle Collision Experiment Bias Analysis Results"!"

Zhang Shuo stood up.

Everyone in the venue looked over together.

Zhang Shuo was one of the focus figures of this high-energy physics conference, and no one expected that he would give a report on behalf of the Computing Center.

Gao Hongli was surprised and asked, "Zhang Shuo, are you giving a report?"

"Isn't it Kevin Cui?"

Tan Zhiming also turned his head in confusion.

Cui Kaiwen explained, "Our results are related to the deviation analysis algorithm, which is Zhang Shuo's research, and he is the most suitable person to make the report."

At this time, Zhang Shuo had already walked to the podium.

He kept a polite smile on his face and said, "Everyone has heard the title of the report, so I will first give a very boring introduction."

"Deviation!"

He said as he wrote the word 'Deviation' on the whiteboard.

"Bias is a summary value that describes the deviation between experiments and simulations, and can be used to measure the total deviation between real experiments and simulations."

“This shouldn’t be hard to understand, right?”

After he asked this question, he started talking about how to calculate the deviation.

This involves a deviation assessment system, which embeds the accumulated deviation value into the algorithm and finally calculates a total deviation.

Zhang Shuo’s explanation was very detailed.

Even if you don't understand the deviation assessment system, you can understand the specific meaning of "deviation degree".

After Zhang Shuo finished talking about "deviation", he used the computer to project the screen to show the deviation analysis results and the analysis data related to the results to the conference site.

Two of the pictures show particle faults, and one of the pictures shows directional deviation of massive particles.

Zhang Shuo explained, "We can see that there are special phenomena in these images, either particle faults or directional deviations of massive particles. Normally, for an experiment that is severely affected like this, the deviation should be higher."

"But as you can see from the actual calculation results, the values ​​have not increased significantly."

"So we think there's some unknown physics going on in the experiment."

When this was said, the reaction on the scene was not intense.

Many people are also discussing this.

If that were the case, it would be hard to call it an 'unknown physical phenomenon'. It could only be called an 'unexplained data analysis result' because the data were analyzed by the computing center and other institutions do not have a deviation analysis algorithm program, so they cannot make the same analysis and therefore cannot verify it.

This is exactly the same as imagined.

Zhang Shuo didn't care about the audience's reaction.

He kept a polite smile on his face and continued, "In particle collision experiments, there is a data that is always ignored - energy loss."

"It's hard to say what the data is useful for. Most of the time it's useless, and some experiments don't even perform calculations."

"Now I've found a use for it..."

After these words were spoken, the venue suddenly fell silent.

Energy loss in particle collision experiments? Everyone understood the meaning of this word, but no one knew what Zhang Shuo was going to say.

Energy loss, what’s the point?
There are too many factors involved in this value, and the most likely cause of energy loss is detection.

Even if the detection problem is ruled out, it may be caused by other reasons. This is one of the problems that cannot be clarified in particle collision experiments.

A few decades ago, many physicists were interested in this, but after there were no discoveries or even any progress in theoretical research, most people lost interest.

No one is researching it now.

Maybe it's really just a detection problem, or maybe it's the mysterious "particle disappearance phenomenon". Some physicists believe that during particle collisions, some small particles that escape will enter other dimensions.

This is the explanation of string theory.

Fermilab also has a special research group, but the results they publish are somewhat magical and difficult to be accepted by the orthodox physics community.

Another possibility is that there is some physical phenomenon that has not yet been discovered.

When thinking of the last possibility, many people's eyes widened suddenly, "Energy loss, unknown physical phenomenon."

"The current experimental deviation analysis is also the discovery of an unknown physical phenomenon..."

"Is there some connection between the two?"

So many people were thinking that even their breathing became heavy.
