Chapter 598 The New Physics Gate!
"Professor Gao, thank you for your hard work!"

In the control room, Chen Zhou looked at Gao Jie beside him, saying this for the first time.

"Should be."

Gao Jie tilted his head slightly and looked at Chen Zhou with a faint smile on his face.

Compared with this short baseline accelerator neutrino oscillation experiment, other preparatory work.

Gao Jie is very clear that Chen Zhou has entrusted him with an extremely critical task.

Recognized by the entire physics community, the next generation of neutrino experiments in accelerators will focus on providing neutrino fluxes, as well as the size and performance of detectors.

In order to study the neutrino mass sequence, search for new neutrinos, and lepton CP violation and other important physical issues.

From this perspective, the factors of particle accelerator detectors can account for at least half of them.

From this, it can also be seen that Chen Zhou's trust in Gao Jie, and more considerations.

As far as Gao Jie is concerned, he is also very satisfied with the task assigned by Chen Zhou if he can complete it in a timely and effective manner.

Chen Zhou nodded slightly, and didn't say anything more.

Withdrawing his gaze, Chen Zhou began to look at the researchers of the research team who were doing the final inspection.

Cross walked to Chen Zhou at this time, and said softly: "It will take about 10 minutes, the final inspection can be completed."

"En." Chen Zhou responded lightly.

While observing the final inspection work, Chen Zhou also began to recall in his mind that there may be omissions in the whole research.

If not, then of course it's best.

If so, make timely adjustments and improve them.

Particle accelerators have always been an important tool in the field of high-energy physics to study the microscopic world of matter.

However, because of the characteristics of neutrinos, other types of experiments have also been produced in the process of studying neutrinos.

But in Chen Zhou's view, the particle accelerator is always the most effective, an experimental tool.

The neutrino beam produced by the accelerator has the characteristics of high energy, strong flow and good directionality.

For neutrinos, particles that are not well understood by people, it is very suitable for studying them.

Like a conventional device for producing a beam of neutrinos.

It is composed of five parts: proton beam, target, focusing pipe, decay channel, and garbage station.

Among them, the proton beam comes from the particle accelerator.

The "target" for proton impact is usually made of high temperature resistant materials, such as graphite.

It is used to resist the huge heat brought by high-power beam current.

Charged mesons in different directions produced by the collisions will change to the same direction through a focusing pipe with a magnetic field applied.

The focusing pipe is usually designed in the shape of a horn, so that particles with different lateral momentums can be focused.

By changing the direction of the magnetic field, you can select positively or negatively charged mesons as needed.

The focused mesons will produce neutrinos or their antiparticles in a decay channel hundreds of meters long.

Finally, the mesons that have not yet decayed, together with other decay products except neutrinos, are sent to the thick garbage dump to be absorbed to avoid radioactive pollution.

From this device and the whole experiment process, it can also be seen that the detector plays an important role in this.

As for Chen Zhou and the others, this time they used the short-baseline accelerator to conduct neutrino experiments.

The baseline refers to the distance traveled by neutrinos.

After the discovery of the muon neutrino, several accelerator neutrino beams were built around the world.

And neutrino detectors are placed very close to the beam, usually only tens of meters apart, to study the interaction between neutrinos and matter.

This is the short baseline neutrino experiment.

Speaking of which, these short baseline accelerator experiments were originally intended to serve the standard model.

They play a crucial role in the establishment of standard models.

Just like in 1973, CERN observed the process of weak interaction between accelerator muons and hadrons or electrons through "neutral current".

It has become an important evidence for the electroweak unified theory.

And brought the 1979 Nobel Prize in Physics to the three founders of the electroweak unified theory, Weinberg, Salam and Glashow.

After the appearance of neutrinos, particles beyond the standard model.

The later short-baseline accelerator experiments also began to change.

At the same time, it undertakes the task of searching for neutrino oscillations.

However, most of these experiments did not find any change in the type of neutrinos.

The only exceptions are the LSND and MiniBooNE experiments in the United States.

However, the experimental results of these short-baseline accelerators cannot be explained by the existing three generations of neutrino oscillations.

Must introduce the fourth generation, even the fifth generation of neutrinos.

Therefore, the short-baseline accelerator experiment, at this level, has also become an important clue to explore more types of neutrinos.

And this is also one of the reasons why Chen Zhou chose the short baseline accelerator experiment.

Chen Zhou may not be the creator of the neutrino oscillation model, but he will definitely be the perfecter of it.

He is also very likely to be the one who opens the door to new physics.

"Professor Chen, the inspection of the entire accelerator experiment has been completed, and no problems have been found!"

Gao Jie walked up to Chen Zhou after receiving a report from a researcher, and said in a somewhat excited tone.

Chen Zhou nodded, looked at Gao Jie, and said, "Then, the experiment begins!"

The entire research team and all the researchers all evacuated from the accelerator device of this experiment, and returned to the control room of the accelerator experiment in sequence.

"Are you all back?" Chen Zhou tilted his head slightly and asked Cross.

Cross nodded: "We are all back, we can start."

"En." Chen Zhou responded, and immediately walked to the podium in the control room.

Clearing his throat slightly, Chen Zhou said loudly: "Colleagues, after nearly three months of hard work, we are finally ready for experiments on neutrino oscillation-related subjects!"

"Today, we will verify whether the mass order of neutrinos is a positive order, and we will also obtain the size of the CP destruction phase angle, as well as the non-zero heavy neutrinos we have been looking for. There is whether θ23 is equal to 45°, and..."

For the first time, all the researchers heard Chen Zhou's tone with a hint of excitement.

This is also the first time for them to feel that they are so close to the originally illusory things in Chen Zhou's mouth.

"Okay, although I still have a lot to say, I want to tell everyone, but now, let me push open the door of this new physics first!"

"After the experiment, I believe that a grand celebration is waiting for us!"

After saying this, under everyone's expectant and excited eyes, Chen Zhou finally said: "Now, I announce that the Institute of High Energy Physics, Huaguo Academy of Sciences, and the neutrino oscillation accelerator experiment of Chen Zhou's team will officially start!"

As Chen Zhou's voice fell, the researchers who were ready started the formal experiment immediately.

With the generation of neutrino beams in the short baseline accelerator experiment, this experiment that has affected many people has begun!
……

In the Institute of High Energy, the two deputy directors, He Hongyun and Geng Guojian, were getting together and talking about Chen Zhou's experiment.

"Director Geng, do you think he can succeed?" He Hongyun poured a cup of tea for Geng Guojian, and looked out the window intentionally or unintentionally.

Looking at the cup of tea that was about to be filled, Geng Guojian twitched the corner of his mouth slightly, and said, "Whether he succeeds or not, at least we can no longer be like before."

He Hongyun didn't speak, but said instead: "Drink tea, the taste of this tea is quite good."

Geng Guojian picked up the teacup, took a sip, pretended to be drinking tea and said, "The taste is good, but not as good as before."

Hearing this, He Hongyun glanced at Geng Guojian, and finally said slowly: "As soon as the theoretical research paper on neutrino oscillation related topics is published, we are doomed to have no chance of turning the tables."

"Now, if his experiment is successful once, it means that we can no longer use time to talk about things like before."

"After all, he only spent three short months..."

Geng Guojian nodded slightly: "We didn't win him over at the very beginning, so we should have known it would be like this."

He Hongyun suddenly smiled relaxedly: "You said that we have understood it long ago after all these years?"

Geng Guojian was stunned for a moment, then smiled and said, "It should have been understood a long time ago. The environment of Huaguo's academic circle will be changed sooner or later. It's just a matter of time."

"But now, the appearance of Chen Zhou obviously fits this opportunity and also conforms to the above meaning."

He Hongyun nodded, and said: "That's the reason. The current Huaguo is no longer the former Huaguo. He needs comprehensive national strength, especially the reserve of high-tech and talents. This will affect the future."

"Yes." Geng Guojian smiled again, and asked, "Should we prepare something?"

He Hongyun replied: "There is still time, wait until his experiment is over..."

"That's right..." Geng Guojian got up slowly, took the cup of tea, walked to the window, and said softly, "Anyway, we are all staring at this experiment right now, don't worry..."

……

Huaguo Science and Technology Department.

Li Zhenbang was walking back and forth anxiously at the same spot.

However, looking at his eyes, there is an uncontrollable excitement.

There is no other reason, it is all because of Chen Zhou's experiment.

As soon as the news of the experiment from Chen Zhou came, Li Zhenbang looked like this.

This can be said to be an experiment related to the future of the high-energy physics community, which has long touched Li Zhenbang's heart.

He has been paying attention to it since the initial project selection.

If it weren't for the intervention of the national science and technology department, how could Chen Zhou have chosen the members of the research team at the beginning?

Can all the elite personnel be selected so smoothly?

Although these elite personnel are not members of the Daya Bay neutrino experiment team.

But relatively speaking, this is already the country, to the greatest extent, supporting Chen Zhou, a leader in scientific research in the new era.

Therefore, looking at the topic that I have been paying attention to, I finally reached the final step of experimental verification.

How can Li Zhenbang calm down in his heart?
Even if he can be counted, he has already experienced a lot of research projects by Chen Zhou.

Suddenly, the phone on Li Zhenbang's desk rang.

He hurried back to his seat and picked up the phone: "Hi, hello, I'm Li Zhenbang..."

Unexpectedly, before Li Zhenbang finished speaking, the voice from the other end of the phone came over.

"Zhenbang, how is the experiment going?"

Li Zhenbang straightened his expression, and quickly said: "Old leader, the experiment should still be in progress. I don't know the specific results of the experiment. As soon as the experiment is over, I will report to you as soon as I receive the news."

Hearing this, the old leader said in a rare way: "It's still in progress? I was thinking about the time, but it seems that I didn't think about it right. Chen Zhou, this experiment has touched the hearts of all of us... "

A smile appeared on the corner of Li Zhenbang's mouth, and said: "Old leader, don't worry, I believe that Professor Chen Zhou will bring us good news."

"Well, I also believe that Chen Zhou will be as successful as before..." After the old leader finished speaking, he ordered again, "That's all right, Zhenbang, I won't disturb your work. When there is news about the results of the experiment, you Remember to tell me as soon as possible!"

"Okay, old leader, don't worry!" Li Zhenning quickly responded.

Then the phone was hung up.

Li Zhenbang put down the receiver in his hand, took out his phone and took another look.

Still no news.

Putting down the phone, Li Zhenbang muttered to himself: "Chen Zhou is also amazing, he has attracted so much attention by himself..."

Thinking of this, Li Zhenbang couldn't help but smiled again.

He suddenly thought of the changes that had taken place in Huaguo's academic circles during the period when Chen Zhou returned to China.

Although very subtle.

However, the result is gratifying.

Putting away his thoughts, Li Zhenbang knew that he couldn't be in a hurry.

All of this depends on Chen Zhou.

If he could get the experimental results out in a hurry, then Huaguo would have already been full of Nobel Prizes.

……

As the main person in charge of the entire experiment, he is also the protagonist of everyone's attention.

Chen Zhou actually didn't know that the leaders of the science and technology department, as well as the old leaders of the country, were also paying attention to this place.

Regarding today's experiment, Chen Zhou himself did not disclose any news.

As for the researchers in the Institute of High Energy, Chen Zhou can think of it.

At this moment, they should and should focus on this place.

As for He Hongyun and Geng Guojian, the two deputy directors, Chen Zhou has never dealt with each other since the last welcome banquet.

Coupled with Chen Zhou's own personality characteristics, and the busyness of research.

For these two people, he naturally didn't have more time to get in touch with them.

Therefore, Chen Zhou didn't think about it at all.

I have actually given it to the two deputy directors of the High Energy Institute.

It has brought some subtle influences to the entire Huaguo academic circle.

And this influence is likely to reach a peak after this experiment.

With so many secretly paying attention, Chen Zhou was only focused on the experiment.

Finally, the experiment came to an end.

In the control room of the laboratory, when the experiment just ended, it was quiet.

But after this brief silence, there was a burst of applause and cheers.

Everyone looked extremely excited.

Everyone looked excitedly at Chen Zhou.

Because, judging from the experimental feedback data.

This time the experiment fit perfectly, the result of Chen Zhou's theoretical research!
Even before the full data analysis, they all have a clear understanding.

This experiment was a success!
The experiment on neutrino oscillation-related subjects was a one-time success!

"Professor Chen, we succeeded!"

"Professor Chen, we succeeded!"

Gao Jie and Cross, standing beside Chen Zhou, shouted almost at the same time.

Chen Zhou, who heard these two shouts, turned his head slightly, and looked at the excited and high-knotted Cross.

He smiled slightly at the two of them, and said softly: "Yes, we succeeded! We opened the door to new physics!"
