Chapter 258 Birthday

A letter sent from the foot of Purple Mountain stirred up a storm among the top leaders.

As the instigator, he had already fallen asleep at this moment.

The next day, early morning.

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

The biting cold wind of winter blew in from the small gap, making the warm room suddenly cold, and also made him shudder and wake up instantly.

This is his habit, which has lasted for at least ten years.

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

After blowing the cold wind for a while, Xu Chuan closed the window and turned to the bathroom to wash up.

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

At Nanjing University, the team led by tutor Chen Zhengping has completed the preliminary analysis of the raw data of the ATLCE detector.

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

After all, NCU is not a formal high-energy research center. Even if some students are studying this, it is impossible for the entire physics department to do so.

Fortunately, Chen Zhengping has 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 NCU. With China now successfully joining CERN, it can be said to be a win-win situation.

Next year, more students from NCU will pass the CERN assessment and join CERN to learn deeper knowledge and more technology there.

For China, talent training can be done anywhere as long as it is domestic.

As for Xu Chuan, he also considered this aspect when choosing to give the Nuclear Energy Research Institute a holiday during the Little New Year. He needs some time to perfect his discovery of inert neutrinos.

After all, this is the result of his previous life and cannot be given up.

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

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

He had not been engaged in high-energy physics research for some time, but it didn't matter. Some things would not fade away with time.

One by one, the Daritz diagrams and various data flashed across the screen in front of him, constantly appearing in his eyes and being filtered out.

Xu Chuan was quite clear about the various characteristics of the inert neutrino.

Because of its characteristics, it was destined that the search for it needed to be carried out from those hidden corners that were counterintuitive.

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

It was called the "invisible man" in the universe by the physics community. It took more than 20 years for the scientific community to predict its existence and discover it.

Because neutrinos have a small mass and no charge, the interaction between other particles is very weak, and coupled with the characteristics that they are easily disturbed, the detectors 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 tens of meters or even hundreds of meters underground.

For example, the IceCube Neutrino Observatory in Antarctica has its deepest observation device located 2,500 meters underground.

In this case, using the Large Hadron Collider to search for neutrinos is simply an unrealistic fantasy.

The little fluctuation produced by neutrinos is like a drop of water in the ocean among the countless data generated by the collider, almost completely mixed with other background noise.

Even the most advanced supercomputers cannot distinguish them at present.

But what if it is an inert neutrino?

This is entirely possible.

Inert neutrinos are defined as the fourth type of neutrino particles in physics.

It is completely different from electron neutrinos, muon neutrinos and tau neutrinos, the latter three of which belong to normal cosmic matter.

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

As dark matter, if it really exists and can be observed, then will its data be 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 discovery of the collider must be confirmed by indirect or direct methods.

In the pages of preliminary analysis data, Xu Chuan looked for the data he needed and selected them to prepare the final Daritz diagram.

However, he was obsessed with work, and the good soundproof environment made him not notice that his mobile phone in the bedroom and the doorbell of the villa were constantly ringing.

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

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

"Is your brother still in the Magic City?" A middle-aged woman next to the girl looked at the villa without any movement and asked.

The sound of ding-ling-ling could be heard outside the quiet courtyard, but there was no movement in the villa.

This makes people wonder if there is no one inside.

"Impossible! I sent a message to my brother yesterday, and he has come back and is 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 something."

Hearing this, the woman and the middle-aged man behind her couldn't help shaking their heads slightly. The woman stretched out her finger and tapped her daughter's head unhappily:

"You girl, you have to surprise and raid, and you didn't tell your brother in advance. Now it's good, I can't contact you."

This is really a criminal record. Once their son gets into scientific research, let alone phone calls, he may not even remember to eat.

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

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

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

As for Zheng Hai, Xu Chuan's family all know him, and they also know that basically where Xu Chuan is, Zheng Hai is there.

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

As Xu Chuan's driver, Zheng Hai naturally recognized Xu Xiao. He nodded and smiled: "Yes, the professor may be busy with his own research. I'll take you in."

As a driver and protection liaison, he naturally has the key and travel authority of this villa.

"Thank you very much, Brother Zheng."

"This is my job."

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

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

Stop working, Xu Chuan got up and walked over.

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

But to his surprise, it was not Zheng Hai who was standing outside the study.

"Surprise! Brother!"

Seeing his brother, Xu Xiao jumped 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: "Xiao Xiao, 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!"

Beside him, Xu's mother also smiled and said: "Xiao Xiao said she wanted to give you a surprise, so she dragged us here. It happened to be 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 you chatted with me yesterday, it was for this."

"Surprise! Touched!" 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 his family to come from afar to celebrate his birthday.

"Brother, you live in such a big house by yourself, I envy you so much."

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

This is her first time here. When Xu Chuan bought the house before, she had already started school and had no time to come. But Xu's father and mother came to visit.

"When you graduate, I will buy you one." Xu Chuan said with a smile. He didn't buy this villa himself, but it was given to him by the country. If he bought it, it would cost about 50 million.

When Xu Xiao graduated, even if he stayed in Beijing to work, he would have enough money to buy her such a villa.

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

He didn't pursue material things very much, but he had to consider his family.

Researchers are also human beings. The situation where one person eats and the whole family is not hungry probably only appears in the conception of boring novelists.

"I don't want it, I can buy it myself!" Xu Xiao raised his head and proudly rejected his brother's kindness.

But then she looked around the villa with her black eyes, and then said: "But I want a room in your villa!"

"Why do you want a room in your brother's villa? Stop it." Before Xu Chuan could speak, Xu's mother glared at Xu Xiao.

In her opinion, this would probably be Xu Chuan's home in the future. Although they were a family, they would eventually grow up and separate.

"Why can't I live in my brother's villa?" Xu Xiao said confidently.

Xu Chuan smiled and said, "Then go pick a room you like."

He looked at his mother and said, "It's okay. There are many rooms in this villa. Anyway, they are all empty and useless. It's lonely for me to live alone. Why don't you move here from your hometown?"

Father Xu shook his head and said, "It's okay to stay for a short time, but forget about moving here. What can we do after moving here? And this should be your wedding room in the future. It's not good for us to live here."

"Also, don't spoil Xiaoxiao too much. Give her whatever she wants."

Xu Chuan smiled and said, "I only have this one sister. Who else can I spoil if not her?"

Aside, Xu Xiao ran over excitedly, hugged his arm and kept shaking it and acting coquettishly: "Brother, you are the best!"

Father Xu smiled and shook his head, and said nothing more.

It is probably the greatest wish of parents that their children love each other.

Xu Chuan continued, "Mom and Dad, how about you spend the New Year here this year?"

He did not persuade his parents to move here again. They have lived in the countryside all their lives and have completely adapted to life there.

And there is nothing wrong with the countryside. As long as the neighbors are harmonious, for the older generation, the countryside is much more comfortable than the city.

Father Xu thought about it, but still shook his head and refused: "You should go back. There are relatives in your hometown waiting for you to go back, and you should go back to worship your ancestors during the New Year."

Xu Chuan nodded. It is indeed very important to worship ancestors during the New Year.

He did not think much about it just now. He just thought that it was the 25th and the whole family was here again, so he didn't bother to go again.

His parents and sister came to celebrate his birthday. Xu Chuan was embarrassed to go into the study to continue his research work. Instead, he prepared to go to the nearby vegetable market with them to buy some vegetables.

He usually did not hire a housekeeper or anything like that. He usually ate takeout and occasionally cooked by himself, which was limited to fast food such as noodles and cooking bags.

This resulted in a lack of ingredients for his parents to cook him a meal.

Originally, he was going to eat out, but no matter how authentic the Hunan restaurant was, it couldn't make the taste of home.

However, as soon as the group went out, they bumped into two other people who came to see him.

"Professor, are you going out?"

At the gate of the villa courtyard, Gu Bing and Amelia stared blankly at Xu Chuan and his group.

Seeing the two students, Xu Chuan patted his head, walked out quickly and said a little embarrassedly:

"Well, my family is coming to celebrate my birthday today. We are just going to go out to buy some food. You go in and sit for a while. I'll be back soon."

When his family came, he forgot that he had called Gu Bing and Amelia yesterday and asked them to come over today.

Of course, it was not to help process data or something, but to check the learning results of the two people in the second half of the year and see how they are now.

After all, after bringing the two from Princeton in the second half of last year, he hardly managed the two.

Although they must have self-consciousness to be able to study for a doctorate, as a mentor, he is indeed a little irresponsible.

So he planned to take advantage of the time before the Chinese New Year to check their homework, and then arrange the homework and teach them after the beginning of the next year.

"Professor, is it your birthday today?" Amelia asked in surprise.

Xu Chuan nodded and said, "Yes, I don't really care. My parents and sister came this year, so I planned to celebrate."

"Happy birthday to you, professor." Amelia curved her crescent moon to bless.

"Chuan'er, do you have anything else to do? If you have something to do, don't waste your time. We can go out at noon."

On the side, Xu's father came over, looked at Xu Chuan, and then looked at Gu Bing and Amelia. He still had some impression of these two people. He had met them once before at the award ceremony in Sweden.

"Brother Gu, sister Amelia!"

Xu Xiao also came over and greeted the two excitedly, then looked at her elder brother: "Brother, go shopping with your parents, I will chat with sister Amelia at home."

She had a very clear memory of Gu Bing and Amelia, strictly speaking, she had a very clear memory of Amelia.

For her, who is obsessed with looks, appearance is justice. Both the senior and Amelia obviously meet this standard. The two exchanged WeChat phone numbers and other contact information and often chatted online.

Xu Chuan thought for a while and said, "Okay, you stay at home with them, we will be back soon."

As he said, he looked at Gu Bing and Amelia: "Xiaoxiao, you all know each other, you three can rest in the villa for a while, just in time for lunch."

"Is it too troublesome? We can come again tomorrow, professor." Gu Bing asked a little embarrassedly.

"It's nothing, just two more pairs of chopsticks, and it's more lively at home." Before Xu Chuan answered, Xu's mother stood up with a smile.

Xu Chuan also smiled and said, "It's okay, just celebrate my birthday. Xiaoxiao, take them in first, I'll be back soon."

"OK, brother!"

Xu Xiao made a "yeah" gesture, pulled Amelia and ran into the room: "Let's go, sister Amelia, the Catrice eye cream you recommended to me last time is really good for reducing dark circles. Do you have any other good cosmetics? Recommend them to me."

PS: The chapter last night was blocked. I wrote some fighter jets and military stuff. I revised it many times but couldn't release it. I can only push it all the way to the beginning.

(Beep, but the things about the stealth series will appear later, everyone can look forward to it)
