A letter sent from the foot of the Purple Mountain stirred up a storm among the high-rises.

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

The next day, early in the 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 through the small gaps, making the warm room suddenly cold, and also making his whole body feel agitated, and he instantly sobered up.

This is his habit and has lasted for at least a dozen years.

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

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

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

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

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

After all, NTU is not a formal high-energy research center, and even if some students are studying this aspect, it is impossible for the entire physics department to be.

However, 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 cultivated a group of scholars in the fields of high-energy physics and particle physics for NTU, which can be described as a win-win situation under the situation that Huaguo has successfully joined.

In the next year, NTU will be able to have more students pass the assessment and join in the study of deeper knowledge and more skills there.

For Huaguo, as long as the cultivation of talents belongs to the country, no matter where it is.

As for Xu Chuan, he also considered this aspect of the choice to take a vacation from the Nuclear Energy Research Institute during the New Year, and he needed some time to refine his discovery of inert neutrinos.

After all, this is the fruit of his previous life, and he can't give it up.

Although this will sacrifice his own rest time, fortunately, the workload is not too big for him now, and if he divides each day during the Chinese New Year equally, the task is not very heavy.

......

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

He hasn't been involved in high-energy physics for a while, but it doesn't matter, there are some things that don't fade over time.

Dashiz charts and various data swiped across the screen in front of him, constantly meeting his eyes, and constantly being filtered out.

The various properties of inert neutrinos are well known to Xu Chuan.

Because of its nature, it is destined to be found from those hidden corners of common sense.

After all, neutrinos themselves are among the most difficult particles in the world to capture and observe, let alone inert neutrinos, which have not yet been found.

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

Due to the small mass and uncharged mass of neutrinos, the weak interaction between other particles, and the fact that 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 tens or even hundreds of meters underground.

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

In this case, the use of a large strong particle collider to find neutrinos is simply an unrealistic fantasy.

The fluctuations produced by neutrinos are almost completely mixed with other background noises like a drop of water in the ocean in the countless data generated by the collider.

Even the most advanced supercomputers are currently indistinguishable.

But what if it's an inert neutrino?

It's entirely possible.

Inert neutrinos are physically defined as the fourth type of neutrino particle.

It is very different from the electron neutrino, the μ neutrino, and the t neutrino, which are all normal cosmic matter.

Whereas inert neutrinos are considered to be one of the warm dark matter.

If dark matter does exist and can be observed, is its data very different from other neutrinos?

It's possible.

Because the interaction between dark matter and normal matter is negligible, other unknown mass or energy deficits can be detected as evidence of the creation of dark matter.

Of course, any discovery of the collider would have to be confirmed by indirect or direct methods.

......

In the pages of preliminary analysis data, Xu Chuan searched for the data he needed and picked them out to prepare for the final Darritz chart.

It's just that he is addicted to work, and the good soundproofing environment makes him not notice that his mobile phone in the bedroom and the doorbell of the villa are constantly ringing.

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

Outside a villa at the foot of the Purple Mountain, an eighteen or nineteen-year-old girl kept pressing the doorbell outside the courtyard with one hand and holding a mobile phone in the other.

"Could your brother still be in the Demon Capital and not come back?" Beside the girl, a middle-aged woman looked at the immobile villa and asked.

The sound of jingling bells could be heard outside the quiet courtyard, but there was no movement inside the villa.

This has to make one wonder if there is no one inside.

"Impossible! I also sent a message to my brother yesterday and he's back, right here! ”

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

Hearing this, the woman and the middle-aged man behind her couldn't help but shake their heads slightly, and the woman was angry and stretched out her finger and pointed at her daughter's head:

"You girl, if you have to make some surprise raids, you won't tell your brother in advance, now it's okay, I can't get in touch."

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

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

Suddenly, out of the corner of her eye, she saw a figure walking towards them, and after glancing at it with some curiosity, she immediately became excited.

"Huh? Wait, that seems to be Brother Zheng, Brother Zheng is here, my brother must be at home! ”

For Zheng Hai, Xu Chuan's family knows each other, and they also know that 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 didn't answer his phone and it didn't work 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 the driver and protection liaison, he naturally has the keys to this villa and the travel authority.

"Thank you so much, Brother Zheng."

"It's 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 woke him up from his immersion.

Stopping his work, Xu Chuan got up and walked over.

Zheng Hai is the only one who can enter this villa directly without saying hello and knock on the study door, and there must be something more urgent in general.

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

“surprise！ Dude! ”

Seeing his brother, Xu Xiao popped 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? Dude! Xu Xiao said with a smile, and then raised the cake box in his hand: "Happy birthday, brother!" ”

Beside her, Mother Xu also said with a smile: "Xiaoxiao, this girl said that she wanted to surprise you, so she dragged us over." It's your birthday today, so let's come over and see how you're doing here. ”

Xu Chuan suddenly looked at Xu Xiao with a smile: "No wonder you kept asking me if I was in Jinling when you chatted with me yesterday, just for this." ”

"Surprise no! Touched no! Xu Xiao asked with a grin.

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

......

"Brother, you live in such a big house alone, and you die of envy."

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

It was the first time she came here, and when Xu Chuan bought a house before, she had already started school, and she didn't have time to come over, but Xu's father and mother came to see it.

"When you graduate, I'll buy you one." Xu Chuan said with a smile, he didn't buy this villa himself, but the state gave it to him, and if he bought it, it would cost about 50 million.

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

This is also one of the reasons why he wanted to get a Chuanhai Materials Research Institute out before.

He doesn't have high material pursuits, but he always has to think about his family.

Researchers are also human beings, and the kind of situation where one person feeds the whole family and does not go hungry probably only appears in the ideas of boring authors.

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

But then her dark eyes looked around the villa twice, and then said, "But you want a room in this villa!" ”

"What do you want your brother's room to do, don't make trouble." Before Xu Chuan could speak, Xu Mu glared at Xu Xiao.

In her opinion, this will probably be Xu Chuan's home in the future, although it is a family, it will always grow up and separate.

"My brother's villa, why can't I live in it?" Xu Xiao said confidently.

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

As he spoke, he looked at his mother and said, "It's okay, there are a lot of rooms in this villa, and they're all empty and useless anyway, and it's very lonely for me to live alone, or you will also move from your hometown?" ”

Father Xu shook his head and said, "It's okay to stay for a short time, just move here, what can we do after moving over?" And this should be your future wedding room, and it's not good for us to live in. ”

"Besides, don't be too used to Xiaoxiao's girl, what do you want."

Xu Chuan said with a smile: "I'm just this one sister, who don't spoil her?" ”

On the side, Xu Xiao ran over excitedly, holding his arm and shaking coquettishly: "Brother, you are the best!" ”

Father Xu shook his head with a smile and didn't speak again.

Their children love each other, which is probably the greatest wish of parents.

Xu Chuan continued: "Mom and Dad, why don't you celebrate the New Year here this year?" ”

He didn't persuade his parents to move over, they had been in the countryside all their lives and had fully adapted to life there.

And there is nothing bad about the countryside, as long as the neighborhood is harmonious, for the older generation, it is far more comfortable in the countryside than in the city.

Father Xu thought about it, but still shook his head and refused: "It's better to go back, there are still relatives in my hometown who are waiting for you to go back, and you have to 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 really didn't think much about it just now, but he just felt that now that it was the twenty-fifth and the family was coming over again, he shouldn't bother to run again.

.......

His parents and sister came to celebrate his birthday, and Xu Chuan was no longer embarrassed to go to the study to continue his research work, but instead prepared to go to the nearby vegetable market to go shopping and buy some vegetables or something.

He usually doesn't hire a housekeeping aunt or anything, and his usual meals are usually takeout, and occasionally his own cooking is limited to fast food such as noodles and cooking kits.

This led to the fact that his parents came and wanted to cook a meal for him, but there were no materials.

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

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

"Professor, are you going to go out?"

At the door of the courtyard of the villa, Gu Bing and Amelia looked at Xu Chuan and his party in a daze.

Seeing the two students, Xu Chuan patted his head, walked out quickly, and said with some embarrassment:

"What, my family came over to celebrate my birthday today, we were just about to go out and buy some food, you guys go and sit down for a while, I'll be back soon."

As soon as the family came, he forgot to call Gu Bing and Amelia yesterday and asked them to come over today.

Of course, it's not to help process the data or anything, but to check the learning results of these 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 barely took care of the two.

Although he can get a doctorate, he must have consciousness, but as a mentor, he is indeed a little irresponsible.

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

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

Xu Chuan nodded and said, "Yes, in fact, I don't care much, my parents and sister came over this year, so I'm going to celebrate." ”

"Happy birthday, Professor." Amelia bent the crescent moon and blessed.

"Chuan'er, are you still in trouble? If you have something to do, then don't delay your time, just go out at noon. ”

On the side, Xu's father walked over, looked at Xu Chuan, and then looked at Gu Bing and Amelia, he still had some impressions of these two people, and he had met at the award ceremony in Sweden before.

"Brother Gu, Sister Miria!"

Xu Xiao also came over, greeted the two excitedly, and then looked at his brother: "Brother, you go grocery shopping with your parents, and Sister Emilia and I will talk at home." ”

Her memory of Gu Bing and Amelia is very clear, strictly speaking, the memory of Amelia is very clear.

For her, Yan Kong, appearance is justice, whether it is that senior sister or Amelia, they obviously meet this standard, and the two also exchanged contact information such as prestige phone numbers with each other, and often chatted online.

Xu Chuan thought for a while and said, "That's okay, you can accompany them at home, and we will be back soon." ”

As he spoke, he looked at Gu Bing and Amelia: "Xiaoxiao, you all know each other, the three of you can rest in the villa for a while, you can eat here at noon." ”

"Won't it be too much trouble, we can come back tomorrow, Professor." Gu Bing asked a little embarrassed.

"It's nothing, it's a matter of two more pairs of fast children, and some people at home are also more lively." Before Xu Chuan could answer, Xu Mu stood up with a smile.

Xu Chuan also smiled on the side: "It's okay, just celebrate my birthday." Xiaoxiao, you take them in first, I'll be back soon. ”

】

"O gotta k, dude!"

Xu Xiao compared, pulled Amelia and ran towards the room: "Let's go, Sister Miria, the catrice eye cream you and I recommended last time is really powerful for dark circles, and there are other useful cosmetics, recommend them to me again." ”
