Chapter 265 The Results that Shocked the World!

In the office, Liu Gaojun looked at Xu Chuan with a confused expression.

He doesn't understand! I really don’t understand!

Even though he was an educator, the principal of a strong C9 school, and he also studied science, he really didn't understand what the two were communicating.

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, has dark matter been discovered?

Thinking about it, Liu Gaojun's heartbeat skipped half a beat. If this were true, that would be incredible!

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 mysterious particle in his mind that has not been confirmed has begun to unconsciously shift towards the sterile neutrino.

What his student said does make sense, and is completely tenable in theory.

But to be honest, he still couldn't believe that this was a sterile neutrino.

What are sterile neutrinos?

According to current physical assumptions, sterile neutrinos are particles that constitute dark matter.

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

He had reservations about it.

After all, it has been a while since the LHC was upgraded in 2015, but I have never heard of CERN discovering traces of dark matter.

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

Upon hearing this answer, Chen Zhengping's pupils shrank, opened his mouth, and asked: "It's not dark matter in the traditional sense. What do you mean?"

"literal meaning."

Xu Chuan smiled and replied: "In my analysis and speculation, there is a high probability that sterile neutrinos are not dark matter, or in other words, they are not dark matter as defined by the current physics community."

"In my opinion, it should be some of the particles released when dark matter particles are formed."

"Just like neutrinos, traditional neutrinos do not exist in the nucleus of atoms. They are just particles with zero rest mass, electrical neutrality, and different from photons produced during the decay of atoms."

"The sterile neutrino also has the possibility that it may be an incidental particle produced by dark matter or the decay of the Higgs field."

"This kind of particle, like neutrinos, is different from dark matter and traditional matter to a certain extent. Traditional neutrinos are difficult to observe due to their unique properties, while sterile neutrinos can be detected because of that slight difference. Observed by traditional detectors."

"It is precisely because of this that" the Dalitz diagram drawn from the experimental data collected by the ALICE detector is very strange. It does not show all its energy levels, resonance states, kinematic variables and other information, but It is like a shadow or an appearance. "

"This just shows that the sterile neutrino is likely to be just a particle with some properties of dark matter. It is a new form of particle in an intermediate state between dark matter and conventional particles."

"In other words, it has the properties of both dark matter and regular matter, so we can observe it through the ALICE detector."

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

After thinking for a while, he asked: "Is there any feedback from CERN?"

Xu Chuan shook his head and said: "Not yet, just wait for two days. If there is no news, I will call Professor Witten and ask."

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

The caller ID showed the person he had just spoken to, Professor Edward Witten.

"Hey, Xu Chuan, where are you? Can you come to CERN?" When the call was connected, Witten asked directly.

Xu Chuan shook his head and said, "I'm sorry, mentor, I'm afraid I won't be able to get through there."

Witten quickly said without hesitation: "Well, just give me your address and I'll go find you."

"Well, tutor, just come to Nanda directly. I'll wait for you here." Xu Chuan thought for a while and replied.

"OK."

Witten nodded, and then hung up the phone without further chatting. Xu Chuan didn't have any questions. Coming to see him at this time must be related to the analysis results he sent before.

The stakes are so high that CERN may not be able to sit still.

After hanging up the phone, Xu Chuan turned to the president of NTU and said, "Principal, I'm afraid I'm going to have to trouble NTU in the next two days. A press conference may be held at NTU."

Liu Gaojun said with a smile: "How can this be called trouble? It is an honor for Nanda to be able to hold this kind of press conference."

Although he didn't know exactly what the results of Xu Chuan's research were, he did understand unknown new particles and dark matter.

A press conference involving these things will definitely cause a huge sensation in the physics community and even the scientific community.

As the host of the press conference, NTU will also gain a huge reputation.

With this kind of press conference, any school would just hope that the more the merrier.

What Xu Chuan didn't expect was that the day after Edward Witten made the call, he rushed to NTU with the people from CERN.

In a reception room at NTU, Xu Chuan met the visitors this time, Edward Witten, David Gross, Arthur MacDonald, Francois Engler, and Yoichiro Nanbu.

I won't introduce Edward Witten in detail, he is the only physicist who won the Fields Medal, while David Gross is the current chairman of the CERN Council.

As for Arthur MacDonald, Francois Englert, and Nambu Yoichiro, they are either top experts in particle physics or experts in theoretical physics.

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

Such an exchange lineup is simply luxurious for an unconfirmed analytical data with a confidence level of only 3sigma.

"Professor Xu, long time no see."

In the reception room, David Gross came forward to greet him with a smile, and also sighed.

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

But he didn't expect that in just three or four years, the other party has already stood at the top of the physics community and even the scientific community.

Nobel Prize, Fields Medal, Crafford Prize. A series of honors are added to a teenager in his twenties, which is simply unimaginable.

"Mr. Chairman." Xu Chuan smiled and greeted him. He did not call him Professor Gross, but Mr. Chairman, which showed that he was still a researcher at CERN.

Sure enough, after hearing this title, David Gross's smile became even brighter: "We have all seen the data analysis you sent a few days ago. Today we are here for this matter."

Xu Chuan nodded and asked: "I wonder if the Council will agree to continue to open the LHC and repeat the experiment to collect more data?"

David Gross smiled and said: "This is exactly why we came here."

"Although you have listed the analysis data and Daritz diagram in detail in the email, CERN still has a lot of doubts. If you can answer these doubts, CERN will hold a press conference in China to publicize this new discovery and start subsequent collision experiments and 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 report is very The results are so great. If the verification is successful, this is not only the first time that a new type of particle beyond the standard model has been found, breaking the record, but also the first time that the veil of dark matter has been torn open, allowing us to see the world hidden behind the chaos! "

Xu Chuan smiled and asked: "I wonder what doubts CERN has about this data analysis and the Daritz diagram?"

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

Chen Zhengping, who was accompanying the exchange as a representative of Nanjing University, nodded and said: "Of course, Nanjing University has already prepared it, please follow me."

The group stood up and followed Chen Zhengping to a conference room. David Gross opened his notebook and connected it to the projection equipment.

The data and Daritz diagram analyzed by Xu Chuan were projected on the silver-white screen.

After turning on the projection, CERN's president, David Gross, said solemnly: "Next, we will hold the European Organization for Nuclear Research--2018 ALICE detector 13Tev energy level collision experiment--inert neutrino report meeting."

"The conference speaker is a Chinese scholar--Professor Xu Chuan."

"This report meeting will take a special form. The participants are CERN Council representatives David Gross, Edward Witten, Arthur McDonald, and Francois Engler. The above representatives will fully decide on the findings of this report meeting on behalf of the CERN Council and make decisions on subsequent research."

"."

At first, Xu Chuan thought it was just an ordinary exchange meeting, until David Gross spoke, he realized that this exchange meeting was so formal.

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

He was the speaker, and there were less than ten people in the audience. It can be said that this is the smallest report meeting in the world, but the one with the highest gold content.

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

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

Looking at the people sitting in the conference room, he took a deep breath and said calmly: "I am honored to be here today to give this report."

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

"Here I would like to thank CERN and my alma mater, Nanjing 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 big guys in the audience were not interested in these, so he quickly got to the point.

As he spoke, he pressed the laser pen in his hand, and the first page on the projection screen was turned over, revealing the text inside.

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

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

"So, through the data model search and inspection, I confirmed that in the 120um (rφ direction) beam z observation data of the inner tracking system anti-helium-3 nucleus, a phenomenon unknown to the current physics community appeared."

Without wasting a lot of time on the things on these report documents, Xu Chuan knew what these big guys in the audience really wanted, so he simply passed the report directly.

"My report is over. If you have any questions, you can raise them now. I will do my best to answer your questions."

As soon as he finished speaking, a hand was raised at the conference table.

Xu Chuan looked over and saw that the person who raised his hand was Professor Arthur McDonald, who won the Nobel Prize in 2015 for the discovery of the neutrino oscillation phenomenon.

He nodded and extended his hand to signal the big shot to ask questions.

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

"From this aspect."

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

This was exactly one of the questions raised by Chen Zhengping yesterday, and it was also some speculation that he did not write into the report file. However, the details of Professor McDonald's question were different. He raised it from the perspective of the four fundamental forces.

Waiting for the other party to finish speaking, Xu Chuan smiled: "Theoretically speaking"

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

This report meeting started at nine in the morning and lasted until eleven in the afternoon before it was barely over. The focus is not on the content report in the first half, but on the discussion and exchange in the second half.

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

This was not mentioned in the important data analysis report.

Several people present were quite interested in his statement.

After the report, Professor François Englert, 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 inert neutrino! We have great hope to use this to solve a corner of the mysterious dark matter!"

On the side, David Gross, president of the CERN Council, smiled and said: "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 smiled, which was exactly what he expected.

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

Just as I was about to say something, I heard Gross continue: "Do you know that CERN has held many meetings before coming here? Although your discovery is very important, the board of directors initially planned to arrange two or three collisions in the second half of the year."

"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 too incredible for current observation methods. It can be said that it is completely impossible."

"But today, you convinced all of us!"

"After returning, we will reconvene the board of directors. We will convince others that in the second half of this year, LHC will do its best to capture this mysterious particle, collect more data, and find it as quickly as possible!"

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

PS: I feel that there are some problems with the writing of yesterday and today's chapters. Yesterday's explanations should be put in today's. It's more fun to show off in front of the Nobel Prize bigwigs. I will revise it after this month (I can't revise it now. Large-scale changes will definitely reduce the number of words in the chapters, thus affecting full attendance.)
