From all-round academic master to chief scientist - Chapter 181 Discussion on the Mass of W Boson

Henry and Svensey were not the only ones in the classroom. Not all the undergraduates who had attended the class had left. After recognizing Lin Xiao, they couldn’t help but gathered around them curiously, wanting to know where the math master had come to them. They came to class for something, so they saw Lin Xiao writing various seemingly complicated calculations on paper.

The previous places that quoted physical formulas were easy to explain, but when Lin Xiao used various mathematical methods later, they became increasingly incomprehensible.

These already involve deeper knowledge. If they were asked to go back and think about it, they might be able to figure it out, but it would be very difficult to keep up with Lin Xiao’s pace.

As a result, these students from the physics department felt helpless. If they are good at mathematics, can they do whatever they want?

Naturally, Lin Xiao was not affected by the people around him. After he finished writing on a piece of draft paper, Swensai next to him handed him another piece of paper and asked him to continue writing. That was it until four pieces of paper later.

“Now we can find the unknown number of this equation, and finally solve it to find that this unknown number matches the properties of the photon.”

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

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

“Well, the above are my results.”

After pressing the cap of the ballpoint pen and retracting the refill, Lin Xiao said with a smile.

Svensay smiled and clapped, and said with sincere appreciation: “C’est-incroyable! Yes, very good, Mr. Lin, you successfully explained this issue from your own perspective, which is very exciting.”

This problem is indeed 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 not the focus, but how to explain it from a new perspective, and Lin Xiao has undoubtedly completed its explanation from a new perspective in mathematics.

In Svensay’s opinion, this is the most rare thing.

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

Now, Lin Xiaoneng found an idea and solved it within a few minutes of getting the question. For this, he could only describe his surprise as unbelievable – ‘C’est-incroyable’ .

Lin Xiao put down his pen and said modestly: “Mainly because this question does not exceed my knowledge reserve, so I can still give an answer.”

Svensay waved his hand: “There is no need to be humble if you are capable. You have done a great 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 care of me.”

“It’s okay to take you with me, but I won’t admit that you are mine!”

Lin Xiao’s look of avoiding him made everyone around him laugh.

Henry also quickly put down his hand and said as if I was not ‘that kind of person’: “Don’t get me wrong, my favorite thing is beautiful girls. I just express my respect for you.”

Suddenly, the classroom burst into laughter again.

Seeing this scene, Svensey also smiled slightly, then patted Lin Xiao and said, “Okay, Lin, I will send you my project when I get back. From today on, you will be a member of our research team. , I believe you won’t refuse, right?”

“Of course I won’t refuse.” Lin Xiao smiled and nodded, “I have been looking forward to this day for a long time.”

“That’s good.”

Svensey nodded, and after adding his contact information to Lin Xiao, he stopped staying here. After all, he still had his own things to do.

After saying goodbye to Svendao, Lin Xiao turned to look at Henry and said, “Let’s go, let’s have a meal together?”

“good!”

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

“By the way, didn’t you do a project with Professor Swansey?”

Lin Xiao asked as he ordered a few meals and ate them.

“I’m also doing it, but Professor Swansey usually doesn’t ask me too much. I mainly work on my own projects.”

Lin Xiao nodded understandingly.

“Speaking of which, Professor Swansey has been studying W bosons and Z bosons, and his topic is about W bosons. In the high-energy physics community, the study of W bosons started in 1983 It has been going on since it was discovered in 2000. After all, the God particle is closely related to the W boson and the Z boson.”

“So I also recommend that you read more papers in this area before then.”

“However, recently I heard that Professor Swansey encountered a troublesome problem, which is the method of measuring the mass of the W boson.”

“What is the mass of the W boson?”

“Yes.”

Henry nodded, picked up the bowl of 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 measurement 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 at the center of the sun! What if If the speed of solar fusion is slightly doubled, then we humans may not even have to consider it.”

“Fusion rate?” Lin Xiao did a little calculation in his mind and came to the result: “I can calculate this. If it is lighter, the rate of light nuclear fusion will be faster. Our sun’s lifespan is not Is it only 10 billion years old? If its burning rate were doubled, it would indeed prevent the birth of humans.”

Henry opened his mouth and said helplessly: “Okay, I used the wrong word.”

It seems that this kind of result can be deduced using a few physical formulas, so he does not need to say ‘can you imagine it? ’ Let’s ask Lin Xiao this kind of sentence.

“In short, that’s it. Anyway, the accurate measurement of the mass of the W boson has always been a flagship project at our particle collider. I heard that Fermilab in the United States is launching a large-scale project in recent years. , intends to re-statisticate the relevant data in the past, and then re-examine the mass of the W boson, but they don’t know how long it will take them, maybe it will take several years.”

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

How many mysterious things are hidden between those particles?

He has reason to believe that a major key point in the truth of the universe must be inseparable from these basic 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 finishing the meal quickly, Lin Xiao did not forget that there was a cat waiting for him to feed him in the dormitory, so he said goodbye to Henry and returned to the dormitory.

After pouring cat food and water for Mimi, Lin Xiao sat at the computer desk and continued working, such as checking papers related to the measurement of the W boson mass.

Their dormitory is called a ‘studio’ by the students, basically because students basically conduct their research in the dormitory.

However, when Lin Xiao turned on the computer, he found that Professor Swansey had sent him various materials. After taking a look, he found that they were related to the topic.

“Hmm… Provide a more accurate angle coefficient through the finite transverse momentum measurement of the W boson?”

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

Then Professor Swansey sent him various other information and related information that needed 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 it.” Take a look and hold a meeting. 』

IN2P3?

Lin Xiao thought about it and quickly remembered that this is a research institution called the French National Institute of Nuclear and Particle Physics. This institute has many particle accelerators and is a partner with the European Organization for Nuclear Research.

For Professor Swinsey’s project, of course, it is necessary to go to such a place.

So he replied: “Okay, Professor.” 』

Subsequently, he began his own study and research.
