Great Country Academician

In the office, Liu Gaojun looked at Xu Chuan in bewilderment.

He can't understand! I really don't understand!

Regardless of whether he is an educator, or the principal of a strong C9 school, and he also studies science, but he really didn't understand what these two were talking about.

I only know that it seems to be related to CERN in Europe, as well as neutrinos, dark matter, etc. Could it be that Professor Xu discovered a new particle? Or, have dark matter been discovered?

Thinking about it, Liu Gaojun's heartbeat missed half a beat. If this is true, it would be terrible!

On the opposite side, after listening to Xu Chuan's evidence, Chen Zhengping fell into deep thought.

It has to be said that after listening to this, the unidentified mysterious particle in his mind has begun to drift towards the inert neutrino unconsciously.

What his student said is indeed very reasonable, and theoretically it is completely tenable.

But to be honest, he still can't believe that this is an inert neutrino.

What are sterile neutrinos?

From the current physical hypothesis theory, inert neutrinos are the particles that make up dark matter.

But can the detectors manufactured by human technology really detect traces of dark matter?

He has reservations about it.

After all, it has been a while since the LHC was upgraded in 15 years, but it has never been heard that CERN has found traces of dark matter.

To this question, Xu Chuan smiled and replied: "What if inert neutrinos are not dark matter in the traditional sense?"

Hearing this answer, Chen Zhengping's pupils shrank, he opened his mouth, and asked, "It's not dark matter in the traditional sense, what do you mean?"

"literal meaning."

Xu Chuan replied with a smile: "In my analysis and speculation, there is a high probability that inert neutrinos are not dark matter, or dark matter as defined by the current physics world."

"It seems to me that it should be part of the particles released by the dark matter particles when they were formed."

"Just like neutrinos, traditional neutrinos do not exist in the nucleus of an atom, but are merely a zero-rest mass, electrically neutral particle that is different from a photon produced during the decay of an atom."

"The same possibility exists for the sterile neutrino, which could be an incidental particle produced by the decay of dark matter or the Higgs field."

"This kind of particle is the same as the neutrino, which is different from dark matter and traditional matter to a certain extent. The traditional neutrino is difficult to be observed because of its unique properties, while the inert neutrino can be observed because of the slight difference. observed by conventional detectors."

"It is precisely because of this that the Daritz diagram drawn from the experimental data collected by the ALICE detector is very peculiar. It does not fully display its own energy levels, resonance states, kinematic variables and other information, but It is like a shadow. "

"This just shows that the inert neutrino is probably only a particle with some properties of dark matter, and it is a new form of particle in the intermediate state between dark matter and conventional particles."

"In other words, it has some properties of dark matter and conventional matter at the same time, so we can observe it through the ALICE detector."

Hearing this, Chen Zhengping nodded in agreement. Judging from the analysis data and Dariz diagram sent to him by Xu Chuan, it really fits these characteristics.

After thinking about it, he asked, "Is there any feedback from CERN?"

Xu Chuan shook his head and said, "Not yet, wait for two more days, if there is no news, I will call Professor Wei Teng to inquire."

As soon as he finished speaking, the phone in his pocket vibrated.

The caller ID was exactly the person he had just mentioned, Professor Edward Witten.

"Hello, Xu Chuan, where are you? Is it convenient to come to CERN?" Wei Teng asked directly when the phone was connected.

Xu Chuan shook his head and said, "I'm sorry, Teacher, I'm afraid I won't be able to make it over there."

Wei Teng said quickly without hesitation: "Well then, give me an address, and I'll go find you."

"How about it, mentor, you can just come to Nanjing University directly, and I will wait for you here." Xu Chuan replied after thinking for a while.

"OK."

Wei Teng nodded, and then hung up the phone without talking much. Xu Chuan was fine and had nothing to do. Coming to him at this time must have something to do with the analysis results he sent before.

The matter is of great importance, and it is estimated that CERN will not be able to sit still.

After hanging up the phone, Xu Chuan turned to look at the principal of Nantah University, and said, "Principal, I'm afraid I will trouble Nantah University in two days, and a press conference may be held at Nantah University at that time."

Liu Gaojun said with a smile: "How can this be called trouble? It is an honor for Nantah University to hold such a press conference."

Although he doesn't know exactly what the results of Xu Chuan's research are, he does understand such things as unknown new particles and dark matter.

A press conference involving these things is sure to cause a great stir in the physics community and even the scientific community.

As the host of the press conference, Nantah University will also increase its reputation greatly.

With such a press conference, any school would only hope that the more the better.

What Xu Chuan didn't expect was that the day after Edward Witten made the phone call, he rushed to Nanjing University with the CERN staff.

In a reception room of Nantah University, Xu Chuan met the visitors this time, Edward Witten, David Gross, Arthur Macdonald, Francois Engler, Nambu Yoichiro.

Edward Witten will not introduce much, the only person who has won the Fields Medal as a physicist, and David Gross is currently the chairman of the CERN Council.

As for Arthur Macdonald, François Engler, Nambu Yoichiro and others, they are either the top experts in the field of particle physics or the experts in theoretical physics.

Moreover, all the people who came to participate in this exchange, except Edward Witten, have won the Nobel Prize in Physics.

Such an exchange lineup is extremely luxurious for an analysis data that has not yet been confirmed and has a confidence level of only 3sigma.

"Professor Xu, long time no see."

In the reception room, David Gross came forward to say hello with a smile, and sighed.

When Xu Chuan went to CERN to study experiments with Edward Witten, he was very optimistic, thinking that this young man would definitely make some achievements in the future.

It's just that they didn't expect that in just three or four years, the other party had already stood at the pinnacle of the physics world and even the science world.

The Nobel Prize, the Fields Medal, the Craford Award... a series of honors added to a teenager in his twenties is simply unimaginable.

"Mr. Chairman." Xu Chuan greeted with a smile. He didn't address Professor Gross, but Mr. Chairman, which showed that he was still a researcher at CERN.

Sure enough, after hearing this name, the smile on David Gross's face became even brighter: "We have read the data analysis you sent a few days ago, and we are here today for this matter."

Xu Chuan nodded and asked, "Whether the board of directors will agree to continue to open the LHC and repeat the experiment to collect more data?"

"That's exactly what we're here for," David Gross laughed.

"Although you have listed the analysis data and the Darritz map in detail in your email, CERN still has a lot of doubts. If you can answer these doubts, CERN will hold a press conference in Huaguo. While disclosing this new discovery, follow-up collision experiments will be launched to conduct special research."

After a pause, the chairman of CERN continued: "Of course, the premise is that you have to convince us today."

"After all, your discovery is really huge. If the verification is successful, it will not only be the first time to find a new type of particle beyond the standard model, breaking the record, but also tearing away the veil of dark matter for the first time. Let us see the world hidden behind that chaos!"

Xu Chuan asked with a smile: "I don't know what doubts CERN has about this data analysis and Daritz map?"

David Gross glanced at the people in the reception room, and then his eyes fell on Chen Zhengping who was attending together. He asked, "Professor Chen, can you trouble your school to arrange a conference room with projection equipment?"

Chen Zhengping, who accompanied the exchange as a representative of Nantah University, nodded and said, "Of course, Nantah University has already made preparations, everyone, please come with me."

A group of people got up and followed Chen Zhengping to a meeting room. David Gross opened his laptop and connected it to the projection equipment.

On the silver-white curtain, what was projected was the data analyzed by Xu Chuan and the Daritz map.

After turning on the projection, David Gross, the chairman of CERN, said solemnly: "Next, the CERN-2018 ALICE Detector 13Tev Energy Level Collision Experiment-Inert Neutrino Reporting Conference will be held. .”

"The speaker of the conference is Professor Xu Chuan, a scholar from Huaguo."

"This report will take a special form. The participants are representatives of the CERN Council David Gross, Edward Witten, Arthur Macdonald, and François Engler. The above representatives will replace the CERN Council members. We will have full authority to decide on the findings of this report meeting and make decisions on follow-up research."

"."

At first, Xu Chuan thought that this was just an ordinary exchange meeting. It wasn't until David Gross spoke that he realized that the exchange meeting was actually so formal.

Well, this should not be called an exchange meeting, but a report meeting.

The speaker was him, and the audience was less than ten people. It could be said to be the smallest but most valuable report in the world.

After briefly describing the process of this small report meeting, David Gross looked at Xu Chuan.

Xu Chuan nodded, got up and walked to the projection screen.

Looking at the few people sitting in the conference room, he took a deep breath and said calmly, "It's an honor to stand here today and give this report."

"At the end of 2018, I accidentally learned that LHC had conducted a 13Tev energy level collision experiment to simulate the scene of the Big Bang. I was very interested in this and I contacted CERN to ask for a We will analyze the original data of this collision experiment, hoping to discover some new things or phenomena.”

"Here, I would like to thank CERN and my alma mater, Nantah University, for their support. It is because of their help that this discovery was made."

After briefly introducing the background of this discovery and thanking CERN and his alma mater for their help as usual, Xu Chuan knew that the bigwigs in the audience were not interested in these things, so he quickly got to the point.

While speaking, he pressed the laser pointer in his hand, and the front page on the projection screen was flipped open, revealing the text inside.

"When analyzing this collision data, I accidentally found that in the data of the ALICE detector, in the observation data of the 120um (rφ direction) beam z of the anti-helium-3 nucleus in the inner tracking system, there is an unexpected There is a signal data of a quantum drop."

"At first, I thought it was just an ordinary quantum fluctuation or background clutter, but after analysis, I also found this phenomenon in another data."

"Thus, through the search and inspection of the data model, I confirmed that in the 120um (rφ direction) beam z observation data of the anti-helium-3 nucleus in the internal tracking system, a phenomenon that is currently unknown in the physical world appeared."

He didn't waste a lot of time on the things in these report documents. Xu Chuan knew what the big cows in the audience really wanted, so he simply passed the report directly.

"My report is finished. If you have any doubts, you can raise them now. I will do my best to clear up your doubts."

After the words fell, a hand was raised by the conference table.

Xu Chuan looked over, and the one who raised his hand was Professor Arthur Macdonald, who won the Nobel Prize in 2015 for his discovery of neutrino oscillations.

Nodding his head, he stretched out his hand to signal the big cow to ask a question.

Professor Arthur Macdonald stood up, looked directly at Xu Chuan, and asked: "According to the comprehensive analysis of the observational data currently available in the physics world, the main component of dark matter should not be any known microscopic elementary particles. It is only Participate in gravitational interactions and weak photon interactions."

"From this point of view."

As soon as Professor Arthur Macdonald opened his mouth, Xu Chuan knew what he wanted to say.

This is one of the questions Chen Zhengping raised yesterday, and it is also some speculation that he did not include in the report. However, the details of Professor MacDonald's question are different. He raised it from the perspective of the four fundamental forces.

Waiting for the other party to finish speaking, Xu Chuan put a smile on his face: "Theoretically speaking"

In the conference room, Xu Chuan answered some doubts in the minds of the big cows.

The report meeting started at nine o'clock in the morning and lasted until eleven o'clock in the afternoon. The focus is not on the content report in the first half, but on the discussion and communication in the second half.

Especially when Xu Chuan proposed that inert neutrinos might not belong to dark matter, but a kind between dark matter and conventional matter, the whole conference room was full of astonishment.

In that important data analysis report, this was not mentioned.

Several people present were quite interested in the statement he made.

After the report was over, Professor François Engler, who had a white beard and smiled like Santa Claus, stood up and patted Xu Chuan on the shoulder, saying with a smile:

"This is a discovery that shocked the world. I now believe that the mysterious particle is the inertial neutrino! We have great hope to unlock a corner of the mysterious dark matter!"

On the side, David Gross, the chairman of the CERN Council, said with a smile: "This is a very satisfactory exchange. According to the final statement, CERN will update the arrangement of the collision experiment in the second half of this year."

Hearing this, Xu Chuan showed a smile on his face, which was exactly what he said he was looking forward to.

As long as there are more collision experiments, more data can be harvested, thereby increasing confidence and thoroughly confirming the existence of sterile neutrinos.

Just when he was about to say something, he heard Gross continue: "You know, before coming, CERN has held several meetings. Although your discovery is very important, at the beginning the board of directors was only planning to arrange two meetings in the second half of the year. Three collisions."

"After all, many people think that this may be just some unknown phenomenon or some undiscovered new particle. Dark matter can be observed. This is really incredible for the current observation methods. It can be said that it is completely wrong. possible things."

"But today, you convinced us all!"

"After we go back, we will reconvene the council, and we will convince others that in the second half of this year, the LHC will go all out to capture this mysterious particle, collect more data, and find it as quickly as possible!"

"If nothing else, this may be the greatest and most important new discovery after the Higgs particle!"

ps: I feel that there are some problems in the chapters written yesterday and today. Those explanations yesterday should be put in today. It’s better to pretend to be bi in front of the Nobel laureates. I will revise it after this month is over (I can’t do it now Changes, large-scale changes will definitely reduce the number of chapters, which will affect full attendance.)
