A letter sent from the foot of Purple Mountain caused a stir among senior officials.

But as the initiator, he has already fallen asleep at this moment.

The next day, early morning.

After opening his eyes from the bed, Xu Chuan stood up and opened the bedroom window.

The biting cold wind of winter blew in through the small gap, causing the warm room to suddenly become cold. It also made him shiver and wake up instantly.

This has been his habit for at least ten years.

In winter, if you want to wake up as quickly as possible in the early morning, this is definitely the fastest and most effective way.

After the cold wind blew for a while, Xu Chuan closed the window, turned around and went into the bathroom to wash up.

After running for several kilometers along the road at the foot of Purple Mountain, he returned to his study and turned on his computer.

At NTU, a team led by mentor Chen Zhengping has completed preliminary analysis of the original data from the ATLCE detector.

The analyzed data was only sent to him yesterday. The speed was not very fast, but it was not slow either.

After all, NTU is not a formal high-energy research center. Even if some students are researching in this area, it is impossible for the entire physics department to be.

Fortunately, Chen Zhengping has quite a lot of experience, and with the assistance of formal researchers such as Lin Feng and Qi Xishao, it is still possible to process these raw data.

This data analysis has trained a group of scholars in the fields of high energy physics and particle physics for NTU. With China now successfully joining the program, it can be said to be a win-win situation.

Next year, NTU will be able to have more students pass the exam and join there to learn deeper knowledge and more technologies.

For China, as long as the cultivation of talents belongs to the country, it doesn't matter where it is.

As for Xu Chuan, he also had this consideration in choosing to take a holiday at the Nuclear Energy Research Institute during the Chinese New Year. He needed some time to perfect his discovery of sterile neutrinos.

After all, this is the result of his previous life and he cannot give up.

Although this will sacrifice his own rest time, fortunately, the workload is not too heavy for him now. If it is divided equally into every day during the New Year, the task is not too heavy.

...

In the study, Xu Chuan flipped through the collision data in front of him.

He has not engaged in high-energy physics research for a while, but this does not matter, some things will not be erased with time.

Pictures of Darize and various data flashed across the screen in front of him, constantly coming into his eyes, and being filtered out again and again.

Xu Chuan is quite clear about the various characteristics of sterile neutrinos.

Because of its characteristics, it is destined to search for it from hidden corners that defy common sense.

After all, neutrinos themselves are one of the most difficult particles to capture and observe in the world, let alone sterile neutrinos that have not been found so far.

It is known as the "invisible man" in the universe by the physics community. It took the scientific community more than twenty years to predict its existence and discover it.

Since neutrinos have a small mass and no charge, the interaction between other particles is very weak, and they are easily disturbed. The detector used to detect neutrinos must be large enough to observe a sufficient number.

of neutrinos.

In addition, in order to isolate cosmic rays and other possible background interference, neutrino detection instruments are often set up dozens or even hundreds of meters underground.

For example, the deepest observation device of the IceCube Neutrino Observatory in Antarctica is located at a depth of 2,500 meters underground.

Under such circumstances, using the Large Strong Particle Collider to search for neutrinos is simply an unrealistic fantasy.

The fluctuations generated by neutrinos are like a drop of water in the sea among the countless data generated by the collider, almost completely mixed with other background noise.

Even the most advanced supercomputers are currently unable to distinguish them.

But, what if it is a sterile neutrino?

This is entirely possible.

Sterile neutrinos are defined in physics as the fourth type of neutrino particle.

It is completely different from the electron neutrino, muon neutrino and t neutrino. The latter three are all normal cosmic matter.

Sterile neutrinos are considered to be a type of warm dark matter.

As dark matter, if it really exists and can be observed, are its data completely different from other positive neutrinos?

This is indeed possible.

Because the interaction between dark matter and normal matter is negligible, if other unknown mass or energy losses can be detected, it can also be used as one of the evidences of the creation of dark matter.

Of course, any collider discovery must be confirmed by indirect or direct methods.

...

Among the pages of preliminary analysis data, Xu Chuan searched for the data he needed and selected them to prepare the final Dalitz diagram.

However, he was obsessed with work and the good sound insulation environment prevented him from noticing that his mobile phone in the bedroom and the doorbell of the villa were constantly ringing.

"Strange, brother, isn't he at home?"

Outside a villa at the foot of Purple Mountain, an eighteen or nineteen-year-old girl kept pressing the doorbell outside the courtyard with one hand, while holding a mobile phone in her other hand. The screen was on, showing that she was making a call.

"Is your brother still in the magical city and not back?" Beside the girl, a middle-aged woman asked as she glanced at the motionless villa.

The sound of jingling bells could be heard outside the quiet courtyard, but there was never any movement inside the villa.

This makes one wonder if there is no one inside.

"Impossible! I sent a message to my brother yesterday. He is back and he is right here!"

The girl replied affirmatively, and then complained: "I guess he is doing some research now and didn't pay attention to the phone or anything."

Hearing this, both the woman and the middle-aged man behind him couldn't help but shook their heads slightly. The woman reached out her finger and tapped her daughter's head angrily:

"You girl, you had to make a surprise surprise and didn't tell your brother in advance. Now that he's gone, you can't even contact him."

This chapter is not over yet, please click on the next page to continue reading! This is really a record. Once their son gets involved in scientific research, he may not even remember to eat, let alone the phone.

Xu Xiao stuck out his tongue playfully, and they all muttered: "You also agreed yesterday, it's not my responsibility alone..."

Suddenly, out of the corner of her eye, she saw a figure walking towards them. After a curious glance, she suddenly became excited.

"Eh? Wait, that seems to be Brother Zheng. Brother Zheng is here, so my brother must be at home!"

Everyone in Xu Chuan's family knows Zheng Hai, and they also know that Zheng Hai is basically where Xu Chuan is.

So after recognizing Zheng Hai's figure, Xu Xiao ran over excitedly and asked, "Brother Zheng, is my brother at home? I didn't answer my phone calls, and it was useless to ring the doorbell."

As Xu Chuan's driver, Zheng Hai naturally recognized Xu Xiao. He nodded and said with a smile: "Yes, Professor, he may be busy with his own research. I will take you in."

As the driver and protection liaison officer, he naturally has the keys and travel authority to the villa.

"Thank you so much, Brother Zheng."

"This is my job."

.......

In the study, Xu Chuan was still carefully searching for what he needed from the analyzed data.

Suddenly, there was a knock on the door, which made him wake up from his immersion.

Xu Chuan stopped working, stood up and walked over.

Zheng Hai was the only one who could directly enter the villa and knock on the study door without saying hello to him, and usually there must be something urgent.

But what surprised him was that the person standing outside the study was not Zheng Hai.

"Surprise! Bro!"

Seeing his brother, Xu Xiao burst out with a smile on his face.

Looking at the figure outside the door, Xu Chuan was stunned for a moment, and then said in surprise: "Xiaoxiao, Dad, Mom, why are you here."

"Surprise? Brother!" Xu Xiao said with a smile, and then raised the cake box in his hand: "Happy birthday, brother!"

Next to her, Xu's mother also smiled and said: "Xiaoxiao girl said she wanted to give you a surprise, so she dragged us here together. It's your birthday today, so we came together to see how you are doing here."

Xu Chuan suddenly realized and looked at Xu Xiao with a smile: "No wonder you kept asking me if I was in Jinling when chatting with me yesterday. It was just for this reason."

"Are you surprised? Are you moved?" Xu Xiao asked with a smile.

"Of course." Xu Chuan smiled and rubbed the girl's head. To be honest, he really didn't expect that his family would come all the way to celebrate his birthday.

...

"Brother, I'm so jealous that you live in such a big house by yourself."

In the huge villa, Xu Xiao ran around, looking at this room and exploring that room.

This was her first time coming here. When Xu Chuan bought a house before, she had already started school and had no time to come over. However, Xu's father and mother came to visit.

"When you graduate, I will buy you a villa." Xu Chuan said with a smile. He did not buy this villa himself, but the country gave it to him. If he bought it, it would cost about 50 million.

When Xu Xiao graduates, even if she stays in the capital to work, he will have enough money to buy a villa like this for her.

This is one of the reasons why he wanted to set up a Sichuan-Hai Materials Research Institute before.

His pursuit of material things is not high, but he must always consider his family.

Scientific researchers are also human beings, and the situation where one person is well fed and the whole family is not hungry probably only appears in the imagination of boring authors.
