From Almighty Scholar to Chief Scientist

Chapter 181 Discussion on the Mass of W Boson
In the classroom, Henry and Svensey were not the only ones. Not all the undergraduates who had attended the class before had left. After recognizing Lin Xiao, they could not help but surround them curiously, wanting to know where the big math expert ran to them. What are they doing in class, so they saw Lin Xiao writing various seemingly complicated calculations on the paper.

The previous references to physical formulas were easy to say, but after Lin Xiao used various mathematical methods, they became more and more incomprehensible.

These have already involved a deeper level of knowledge. If they go back and think about it, they may still be able to figure it out, but it is very difficult to keep up with Lin Xiao's rhythm.

As a result, these students in the physics department felt helpless. Are they good at mathematics, so they can do whatever they want?
Naturally, Lin Xiao was not influenced by these people around him. After he finished writing a piece of draft paper, Svensey next to him handed him another piece of paper for him to continue writing, and it was like this until four papers later.

"Now we can find out the unknown of this equation, and finally, the unknown is in line with the properties of photons."

After writing the last line, Lin Xiao also expressed his final conclusion.

"Of course, the photon that propagates the electromagnetic force is a kind of virtual particle, and this kind of virtual photon can better explain our physical phenomena."

"Well, the above is my result."

Pressing the cap on the ballpoint pen and retracting the refill, Lin Xiao said with a smile.

Svensey clapped his hands with a smile, and praised sincerely: "C'est-incroyable! Not bad, very good, Mr. Lin, you successfully explained this problem from your own point of view, which is very wonderful."

This problem is really not difficult. Of course, this is compared to a student majoring in high-energy physics. As a mathematics major, Lin Xiao can still solve this problem, which already shows his ability in physics.

Of course, solving this problem is also not the point, but how to explain it from a new angle, and Lin Xiao has undoubtedly completed the explanation from a new angle in mathematics.

In Swen Sai's view, this was the rarest thing.

Otherwise, why did he give Lin Xiao a week to think about this problem in the first place, because in his opinion, a week is enough for Lin Xiao to come up with an idea.

But now, Lin Xiaoneng found an idea and solved it in less than a few minutes after he got the question. For this, he can only use unbelievable-'C'est-incroyable' to describe his surprise .

Lin Xiao put down his pen and said modestly: "The main reason is that this question does not exceed my knowledge reserve, so I can still give an answer."

Swen Sai waved his hand: "Those who are capable don't need to be humble, you've done a good job."

"Henry, you should learn more from Mr. Lin."

Henry next to him grabbed Lin Xiao decisively, and said with a flattering expression: "Lin, I will be yours from now on, you must take me with you."

"It's okay to take you, I don't admit that you are mine!"

Lin Xiao's avoidance made everyone around him laugh.

Henry also put down his hand quickly, and said as if I was not that kind of person: "Don't get me wrong, my favorite is beautiful girls, I just express my admiration for you."

Suddenly, laughter broke out in the classroom again.

Seeing this scene, Svensey also smiled slightly, then patted Lin Xiao, and said, "Okay, Lin, I will send you my project after I turn around, and you will be a member of our research group from today on." , I believe you will not refuse, right?"

"Of course I won't refuse." Lin Xiao nodded with a smile, "I've been looking forward to this day for a long time."

"That's good."

Svensey nodded, and after adding contact information with Lin Xiao, he didn't stay here anymore, after all, he still had his own things to do.

After saying goodbye to the gentle track, Lin Xiao turned to look at Henry and said, "Let's go, let's have a meal together?"

"it is good!"

Henry nodded, and then left the classroom with Lin Xiao and came to the dining room.

"By the way, haven't you done a project with Professor Svensey?"

After ordering a few meals, Lin Xiao asked while eating.

"I'm also working on it, but Professor Swensey usually doesn't look for me too much. I mainly do my own projects."

Lin Xiao nodded clearly.

"Having said that, Professor Swensey has been studying W bosons and Z bosons, and his subject is about W bosons. In the field of high-energy physics, the research on W bosons began in 1983 It has been going on since it was discovered in [-], after all, the God particle has a lot to do with the W boson and the Z boson."

"So I also recommend that you read more papers on this subject before then."

"However, recently I heard that Professor Swensey encountered a headache, that is, the method of measuring the mass of the W boson."

"What's the mass of the W boson?"

"Yes."

Henry nodded, picked up a bowl of thick soup next to him, took a sip, and said: "We have been trying to measure the mass of the W boson more accurately, after all, it is an important parameter in our standard model, Precise measurements of its mass can help us test the Standard Model and even discover new physics, after all, it can directly affect the Fermi constant. Can you imagine? Its mass can even determine the rate of fusion in the center of the sun! If If the rate of solar fusion is slightly doubled, then we humans probably don’t even have to think about it.”

"Fusion rate?" Lin Xiao calculated a little in his mind, and then he came up with the result: "I can calculate this. If it is lighter, the rate of light nuclear fusion will be faster. The life span of our sun is not Is it only 100 billion years, if its burning rate is doubled, it will indeed lead to the inability of human beings to be born."

Henry opened his mouth and said helplessly, "Okay, I made a mistake in using the words."

It seems that this kind of result can be deduced with several physical formulas, so he doesn't need to start with 'Can you imagine it? This kind of sentence came to ask Lin Xiao.

"All in all, that's it. Anyway, the precise measurement of the W boson's mass has always been the flagship project of our particle collider. I heard that Fermilab in the United States has launched a large-scale project in recent years. , plan to re-statistic the relevant data in the past, and then re-examine the quality of the W boson, but they don’t know how much time they will spend, maybe it will take several years.”

Listening to Henry's words, Lin Xiao nodded, and at the same time became more interested in the future research.

Between those particles, how many mysterious things are hidden in it?
He has reason to believe that a major point in the truth of the universe must be inseparable from these elementary particles.

Next, the two stopped talking about these academic issues. Although it was in the interests of both parties, sometimes they had to discuss other things, such as other beautiful girls eating in the restaurant.

After eating soon, Lin Xiao didn't forget that there was a Mimi waiting for him to feed in the dormitory, so he said goodbye to Henry and went back to the dormitory.

After pouring cat food and water for Mimi, Lin Xiao sat down at the computer desk and continued to work, such as looking up papers related to W boson mass measurement.

Their dormitories are called "studios" by students, basically because the students' research is basically carried out in the dormitories.

However, after Lin Xiao turned on the computer, he found that Professor Swen Sai had sent him various materials. After a glance, they were related to the subject.

"Hmm...provide a more precise view factor by measuring the finite transverse momentum of the W boson?"

This project can improve the accuracy of the mass detection of the W boson.

Then Professor Swensey sent him various other materials, as well as related materials that need to be used, and then sent another message: "The day after tomorrow, let's go to the IN2P3 Computing Center and take you there to see Take a look and hold a meeting by the way. 』

IN2P3?

Lin Xiao thought for a while, and quickly remembered that this is a research institution called the French National Institute of Nuclear and Particle Physics. This research institute has many particle accelerators, and it is also a partnership with CERN.

For the subject of Professor Swensey, of course, it is necessary to go to this kind of place.

So he replied, "Yes, Professor. 』

Then, he started his own study and research.
