From all-round academic master to chief scientist

"Oh-la-vache!"

In Swensey's room, Swensey exclaimed.

Just now, Lin Xiao and Henry knocked on his door and ran over with computers in their arms. At that time, Svensey was already ready to rest.

But when he saw the data in front of him, he couldn't help showing shock on his face, just like when Henry saw this thing just now.

Seeing Swansey's shocked expression, Henry felt "comfortable" on his face. Since he himself was shocked, of course he also wanted to see the professor's shocked expression.

He said with a smile: "Professor, it seems that you have found a capable helper. Lin can completely replace me in the future."

Svensay glared at him angrily, "It's like you played some role."

"Oh, Professor, if you say that, I will be hurt."

Svensey didn't even look at him. He turned to Lin Xiao and asked impatiently: "Lin, how did you deduce it? Show me your derivation process!"

Lin Xiao then placed the ten pieces of scrap paper he had used in front of Svensey from the side.

Svensey briefly browsed it. Of course, he didn't finish it. He just looked at Lin Xiao's ideas and some important calculation processes. After that, he understood what Lin Xiao meant.

"Beautiful, well done."

Svensay praised, "With your help, it seems that our project will not be over for long."

This is the role of a mathematical genius in their physics community. Just by looking at it, you can find out how to modify their mathematical model.

The original 2% error was directly reduced to 0.01%, a gap of 200 times. This will bring great help to their subsequent research on this topic. Based on this result, it would be impossible to hand the second work directly to Lin Xiao. Problem, Svensey even began to consider giving up one work to Lin Xiao, and then become the corresponding author himself.

Then I thought about it again, how many days had it been since Lin Xiao joined their project?

This made it even more difficult for him to describe his feelings.

Lin Xiao smiled and said: "Since I have joined this project, of course I will do my best."

Svensay nodded with relief: "It would be best if everyone could think so."

Then he glanced at Henry next to him.

Henry said quickly: "I swear, I will work hard in the future."

"You'd better finish your thesis first."

Svensay shook his head, too lazy to say more to Henry.

Then he patted Lin Xiao on the shoulder and said, "Thank you for your hard work. Have a good rest today. Let's go to the computing center to try it out tomorrow!"

Now he is quite looking forward to tomorrow's calculation results.

Through the model revised by Lin Xiao, if they simulate it on the computer tomorrow, the results will definitely meet expectations.

"OK."

Lin Xiao smiled and nodded, then he took the computer and returned to their room with Henry.

However, Lin Xiao did not start to rest. Instead, he took his calculation results and fell into deep thought.

Their purpose is to provide the necessary theoretical guidance to accurately extract the W boson angular coefficient in experimental analysis, and then use this to directly point to the W boson to help measure its mass.

So, besides this direction, what other methods can they use to more accurately measure the mass of the W boson?

Lin Xiao looked down at his calculation results, and finally threw the scratch paper aside.

The angle coefficient is only one aspect. It is limited to one direction. To achieve more perfect results, he must discuss this issue from a higher level, or from the scope of the overall framework.

"The overall framework..."

Lin Xiao silently recited these words in his heart.

W boson, weak interaction...

He found a piece of paper nearby and simply wrote a 'W' on it.

Suddenly, something came into his mind, Higgs mechanism?

Higgs mechanism!

In the Standard Model, the Higgs mechanism is a mechanism that allows elementary particles to generate mass.

Let the particles gain mass!

Once you hear it, you will know how awesome it is.

It is for this reason that the Higgs particle, which appears based on the Higgs mechanism, is also called the God particle. After all, in Western people's minds, only God can create various substances and create mass.

And once humans can master the Higgs particle, then humans will be equal to God. Of course, if humans can really master the Higgs particle completely, it is definitely not something that people of their time should consider.

For Lin Xiao, this is also not the point. The point is whether he can continue to deduce the mass that the W boson should have through the process of giving mass to particles through the Higgs mechanism.

Since the W boson needs to gain mass, it must couple with the Higgs field to gain mass.

So, can he use this method to determine the mass of the W boson?

Although this method sounds ideal, there are still considerable difficulties in actually implementing it, and even Lin Xiao feels that this is far away.

"It's really challenging."

Lin Xiao sighed softly.

After all, there are still questions about whether the Higgs mechanism is perfect, although many accurate predictions have been made based on the standard model of the Higgs field.

Of course, after just thinking about it for a moment, Lin Xiao returned his attention to the manuscript in front of him.

Since there is a problem, solve it. This is what he should do.

"continue."

Then, Lin Xiao wrote down a bunch of formulas and began his own derivation of this difficult problem in physics.

Henry from the back looked at Lin Xiao who was working so hard and sighed, so only such a person can reach where he is now, right?

…

Time passed quickly.

It was impossible for Lin Xiao to solve such a difficult problem in a short time.

So when it was time to retire for the evening, he went to bed.

The next day, their seven-member research team left the hotel and went to the computing center.

IN2P3 Computing Center, as a computing center for scientific research, is responsible for processing various scientific data and providing related computing services. For example, relevant data generated by particle accelerators, astronomical telescopes and satellites during operation are all stored in Here, it is then provided to scientific researchers for analysis.

Especially the relevant data generated by the Large Hadron Collider, this is also one of the main storage centers.

This time Lin Xiao and the others came here just to take advantage of its computing power. Of course, they could also perform calculations by accessing nodes in Paris, but since they were all here, they could just use it on site. Out of the way.

Soon, they entered the relevant data into the calculation program. Of course, the new model modified by Lin Xiao yesterday was also written into it, replacing the previous model with an error of 0.2%.

Then, the calculation starts.

As a series of progress bars appeared, they waited slowly until finally, the result appeared.

"The error is only 4%! Compared with our last NLO-QCD prediction, the scale dependence has been reduced by 2-4 times!"

A postdoc looked at the final result and exclaimed.

Then, they all couldn't help but look at Muguan towards Lin Xiao.

Just because he modified one of the mathematical models, their progress immediately improved so much. As long as the error can be reduced to less than 3%, they can succeed!

In the past, their highest error was more than 10%.

Isn't this Chinese guy a bit too scary?

Of course, the error can be reduced so much this time, and it is indispensable for them to make modifications for so long. However, Lin Xiao's help still provided them with huge help.

After all, the error rate in their estimate this time was 6%, which was completely beyond expectations.

After learning this result, Lin Xiao also smiled slightly, but still felt a little regretful. Although the model he modified reduced its error by 200 times, the model itself did not account for the highest proportion in their entire theory. Therefore, the final calculated error is not directly reduced by the same factor.

Of course, it is quite good to have such results.

At this time, Svensey had already shown a satisfied smile. It seemed that his project might be over in less than two months.

"Thank you, Lin." He patted Lin Xiao on the shoulder, and then said to everyone: "Okay, in order to celebrate our staged success, we invite everyone to have a big meal today!"

"Great!"

Everyone cheered immediately.

Then they packed up their things and went to have a big meal together.

…

Coming here to verify the project was just incidental. The high energy physics seminar the next day was the main purpose.

Arriving at the IN2P3 Computing Center again, Lin Xiao and the others came to one of the large lecture halls.

There were three to four hundred people present. Of course, in addition to various scientists who were truly famous in the academic world, there were also students like Henry who came with their mentors.

"There are quite a lot of people."

Lin Xiao sighed with emotion.

"Well, there are also many big names coming, including Nobel Prize winners in physics, including Higgs. It's a pity that Mr. Yang from China is not coming. He is my idol."

Henry said.

Lin Xiao smiled: "Mr. Yang is over ninety years old and needs a good rest. China is too far from France."

"Okay." Henry said, "Sometimes I really wonder how he discovered parity nonconservation in the first place."

"Why not Yang-Mills gauge theory?"

"No, parity non-conservation sounds cool, but the Yang-Mills gauge field reminds me of the Standard Model. The Standard Model is too troublesome."

Lin Xiao smiled. The standard model is based on the Yang-Mills gauge bin theory. When Yang Zhenning was awarded the Nobel Prize in Physics, one of the award speeches was: "This work has ranked among Newton, Maxwell and Einstein." among the jobs.”

Thinking of Yang Zhenning's work, Lin Xiao also thought of the topic he wanted to study.

How did Mr. Yang complete the proof back then?

He suddenly felt that he could go and ask him. Maybe he could get some inspiration from this senior?
