CERN (full name European anization for Nuclear Research in English, abbreviated as CERN) is an international research institution located in Geneva, Switzerland. It was founded in 1954. CERN's main task is to conduct basic physics research, especially the study of the fundamentals of the microscopic world.

composition and interactions.

As the world's largest particle physics research institution, CERN employs more than 3,000 full-time employees, and about 6,500 scientists and engineers from 80 countries representing more than 500 universities and institutions have been stationed and participated in CERN for a long time.

Various particle experiments.

CERN has the world's largest particle physics experimental facilities, the most well-known of which are the Large Hadron Collider (LHC) in Switzerland and the Super Proton Synchrotron (SPS) on the border of Switzerland.

The funding required for CERN is shared by all member states in proportion to GDP. The annual research funding is about 1 billion US dollars. The funding seems to be a lot, but the experiments are too expensive, and large-scale experiments can only be conducted once every three to five years on average.

Therefore, previous experiments at the Large Hadron Collider have attracted widespread attention. This time, because of Qin Ke and Ning Qingjun’s papers, it has attracted the attention of melon-eating people all over the world.

CERN announced the results of the latest Large Hadron Collider experiment today, which is a voice of CERN to the world. Naturally, it is impossible to just send a spokesperson to deal with the media as before, but to hold it in a very formal manner.

press conference.

Not only were representatives of the 22 member states of the Council present at this press conference, but almost all of the more than 100 members of the Science Policy Committee were sitting in the front row. In addition, there were more than 200 scientist representatives - from CERN alone.

The number of people is close to four hundred.

Seeing the CERN representatives formally seated through the glass door, the reporters were as anxious as ants on a hot pot. When the staff opened the glass door and invited media friends to enter, all the reporters rushed in with a clatter.

It was so crowded that I didn’t know how many glasses were squeezed out and how many leather shoes were stepped on.

Fortunately, CERN staff worked hard to maintain order and no major troubles occurred.

Yuan Zhaoying was coerced by the crowd and involuntarily "swarmed" into the reception hall of the University of Nottingham. While he hurriedly asked the accompanying photographer to follow him, he stretched his neck hard to look at the CERN representatives who were already seated.

I wanted to get some clues from their expressions, but I saw that many scientists had serious expressions and were whispering to each other. Some people seemed to be arguing in low voices, and the atmosphere was quite tense.

As a reporter, Yuan Zhaoying's professional intuition made her keenly aware that this press conference might lead to surprising results.

After almost ten minutes, reporters from various countries took their seats one after another, and the noisy scene in the hall ended. The reporters were relatively well-behaved. Next was CERN's speaking time, and then the interview period, so the reporters worked hard

He suppressed his anxiety and sat in his seat, but the pen in his hand was already rapidly recording the expressions and demeanor of various important people.

For example, Professor Trowitch.

Professor Trowitch is a well-known particle physicist at CERN. He likes to regard himself as an authority on particle physicists on the Internet and make various remarks. Last month, he made wild remarks to deny and criticize the papers of Qin Ke and Ning Qingjun.

The "CERN insider" who criticized was this bald old American professor.

Journalists from various countries who were familiar with the inside story, including Yuan Zhaoying, a reporter from Xiaguo Science Pioneer, naturally looked for Professor Trowitch immediately.

Professor Trowitch had almost lost all his hair, and his bald appearance was still easy to recognize. Soon Yuan Zhaoying found the target person. Professor Trowitch's face was gloomy, his lips were pursed and he said nothing, and he did not talk to the colleagues around him.

The exchange aroused great curiosity in Yuan Zhaoying.

Was it because the pressure from the media made the old man feel unhappy, or was there something unexpected in the results of the experiment?

Yuan Zhaoying became even more curious and asked the accompanying photographer partner to take a few more photos of Professor Trowitch.

At 14:30 in the afternoon, CERN's experimental results conference finally started on time.

The speaker this time was Sir James Lederman, the chief scientist of the Science Policy Committee and a particle physicist from Eagle Country.

Sir Lederman is a fellow of the Royal Society of Eagle, winner of the 1988 Nobel Prize in Physics, and one of the most prestigious physicists at CERN.

The old man was dressed meticulously and wore a black tie. He cleared his throat and began his usual review of experiments. He started by talking about the Large Hadron Collider experiments in the past ten years:

"Since 2012, when we successfully detected the Higgs boson and announced that we had completed the last piece of the puzzle of the standard particle physics model, we have been committed to studying quarks, hadrons, and W through experiments at the Large Hadron Collider.

Conduct more precise measurements and research on particles including the Z boson, Higgs boson, etc. to further understand the properties and interactions of these particles, and at the same time continue to explore dark matter and study new physical models..."

I have to say that the old man is still very capable. It is obviously just a customary opening statement and a boast about CERN, but he can express the complex particle theory in an easy-to-understand language, and it is interesting, even for laymen reporters.

, everyone can learn a lot about the research history of particle physics and the significance of this Large Hadron Collider experiment through this "previous summary" that takes less than ten minutes.

"The Large Hadron Collider experiment we conducted this time was planned three years ago. In the past year, almost 4,000 people have been invested in preparations, and as many as 129 upgrades have been made to the LHC. The upgraded LHC

The particle beam energy has been increased by about 30%, enabling deeper and more precise detection of the properties of elementary particles..."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Sir Lederman’s words are equivalent to refuting the rumors on the Internet that this experiment is to falsify the hypothesis of Qin Kening Qingjun’s paper.

"Next, I will announce the results of this experiment."

Seeing that the old man finally turned the topic to the most critical point, the reporters in the audience suddenly became a little commotion, but soon became quiet again. Everyone pricked up their ears and looked at the old white man on the stage.

Under the nervous gaze of countless people, Sir Lederman motioned to the staff to open a series of charts.

The first big picture that appeared on the big screen was countless dense green dots. Each dot represented a detected impact signal, distributed according to different particle energy segments (unit GeV): "First, let's explain it.

From the massive proton-proton collision data, we can see that in the charged strange charm meson (quark composition is 1 charm quark and 1 antistrange quark) in the bottom meson decay and in the final state of the charged meson, a double

It is a charged particle with decay properties similar to those of ordinary mesons. This is the first time that a double-charged four-quark hadron has been discovered experimentally, and it is also a hadron partner that simultaneously discovered two new quark components..."

Sir Lederman explained one chart after another. The scientists in the audience looked serious, but the reporters gradually became a little dizzy. Although Sir Lederman tried his best to simplify the description of the experimental results, he mainly talked about

It is also the latest discovery of this experiment. The reporters are still getting more and more dizzy the more they listen to it, and they can only utter unclear sighs such as "Wow, it's amazing" and "It sounds incredible."

Finally, Sir Lederman came to the eighth chart. When switching to this chart, Sir Lederman was obviously silent for a few seconds, and the look on his face was different from before, and he looked more solemn.

Many reporters discovered this abnormality and suddenly became energetic.

"This is a measurement result about the mass of the W boson. Measuring the most accurate mass value of the W boson is an important goal in our LHC experiment this time, and the results really shocked us."

More than 99% of the reporters who came to the meeting this time came because of this result. Everyone's nerves were aroused to the point of being tense. Xia Guo reporter Yuan Zhaoying was so nervous that his heart beat faster and his palms became sweaty.

He is not a scientist and is not too concerned about what this experiment will bring to the world of particle physics. He just wants to know whether it will have a positive or negative impact on the two young academicians that his country is most proud of.

And the measurement result of the W boson mass is the key to determining whether it has a positive impact or a negative impact!

Sir Lederman looked around the audience and said solemnly: "Everyone, look at this chart. The precise values ​​of the W boson masses measured in this experiment are distributed on it."

This picture is full of dense red dots, but most of the red dots are concentrated in the upper half of the area, with only one relatively larger red dot in the bottom area.

Except for relevant people from CERN, almost no one present could understand the meaning of this chart, and they couldn't help but look at Sir Lederman anxiously.

Sir Lederman said slowly: "This is the value recorded by the ATLAS and CMS detectors each time. Each red dot represents a specific value. You can see that more than 99.99% of the values ​​are concentrated at 80436.8±

In the area of ​​9.1 MeV/c2, there are only 0.001% values ​​distributed here!”

His fingers placed heavily on the bottom area. His fingers were so hard that they seemed to pierce the projection screen, and his voice became excited.

"This value is - 80466 MeV/c^2! I believe many people here know this value. Yes, this value is what Xia Guo's Nobel Prize winner in physics, Academician Qin Ke and Academician Ning Qingjun, said last time.

In the paper "Proof of the Mass Gap Problem of the Yang-Mills Equation and Mathematical Interpretation of the Standard Model of Particle Physics", through the mass relationship they discovered, based on the mass of the Higgs boson and the mass of the Z boson,

The mass of the top quark and the lifetime of the muon are used to calculate the mass of the W boson!"

With a crash, all the reporters stood up, and someone couldn't help but ask loudly: "Sir Sir Lederman, what does this 0.001% numerical ratio mean? Is there an error in the calculation of the paper?"

Sir Lederman did not blame a reporter for asking questions in advance. He waved his hand and motioned for everyone to sit down before saying in a strong voice: "No, I want to explain again here. Although the value of 80466 MeV/c^2 appears

The ratio only accounts for 0.001% of all measurements, but it’s very special!”

"As you can see, there are no other small points in this area, which means that only this value has been measured! And although it only accounts for 0.001%, it means that there were almost 150,000

The detector recorded this value, but among other values ​​concentrated in the 80436.8±9.1 MeV/c2 area, only 80435.3MeV/c2 was recorded 11,000 times, and the rest of the values ​​were recorded less than 10,000 times!”

"In short, the value of 80466 MeV/c^2 is the value that has been recorded the most, and it is so abruptly outside the main measurement value area that we really cannot judge the experimental error or noise signal. After

After nearly three hours of intense discussion among our entire research team, we came to the conclusion that this value is most likely the exact mass of the W boson, and the reason why it is so different from other values ​​can only mean that

Are there any undiscovered 'substances', 'new particles' or 'physical mechanisms' in nature that have an impact on the mass of the W boson?"

This chapter is not over, please click on the next page to continue reading! "We can basically confirm that this is the first major deviation in the Standard Model of particle physics! It is called a deviation, but it is actually progress! This is an epoch-making discovery! This means

We have touched the door to new physics!”

"Currently, many of our scientists tend to agree with the views put forward by Academicians Qin and Ning, that is, it may be that we failed to measure it. The rumored dark matter caused this error, and we need to conduct a new revision of the Standard Model of Particle Physics.

Correction! In future experiments, we will focus on research and measurement of data in this area, and strive to solve this mystery as soon as possible! Open the door to new physics!"

"Here, we also pay our highest respect to Academician Qin Ke and Academician Ning Qingjun, who relied on their advanced mathematical theory level to calculate the mass of the W boson so accurately! They have created something that we can't even imagine.

A great miracle!"

"We are happy to invite them to join our particle physics research team to provide us with better theoretical hypotheses and jointly prepare for the next Large Hadron Collider experiment and the Large Electron Positron Collider experiment.

!”

There was a brief silence in the audience, and almost all the reporters stood up in disbelief. Then countless flash lights and warm applause completely drowned Sir Lederman!

Xia Guo reporter Yuan Zhaoying, who had been using paper and pen to quickly record Sir Lederman's words, was stunned for a while before he realized what he said, and he was overjoyed!

This is equivalent to CERN experimentally verifying the calculation results of Academician Qin Ke and Academician Ning Qingjun, and publicly recognizing its correctness!

Shocked! Ecstatic! Proud! Proud! Countless emotions surged up. Yuan Zhaoying clapped her hands wildly and shouted excitedly along with other reporters!

His eyes inadvertently fell on Professor Trowitch again. This old man who always liked to talk eloquently had his head drooped like a frost-beaten eggplant, more like a... dog with its spine broken.

.

After getting excited, Yuan Zhaoying remembered that the news must be sent back to China as soon as possible so that people across the country can share this great news!

The tip of the pen was moving rapidly, and Yuan Zhaoying wrote down a news headline that would soon cause a sensation across the country and even the world——
Chapter completed!
