From Almighty Scholar to Chief Scientist

He immediately yelled, but when he sat up from the bed, he glanced at Lin Xiao, and then froze.

Lin Xiao was actually studying.

Seeing him like this, Henry couldn't help but touch his forehead, oh my god, is this a genius?

The genius is still working so hard, no wonder he is so good.

Then he walked up, came behind Lin Xiao, took a look, and saw that Lin Xiao was looking at their thesis, he shook his head helplessly, why couldn't he be so serious?

However, at this moment, he suddenly saw Lin Xiao put down the mouse, and then looked around for something.

Henry guessed what Lin Xiao was looking for, so he took out a draft paper from the side, and put it in front of Lin Xiao.

Seeing this, Lin Xiao was taken aback for a moment, then turned to look at Henry next to him.

"You don't read novels anymore?"

Henry spread his hands, shrugged and said, "Seeing that you are still working, how can I have the nerve to continue watching."

Lin Xiao smiled: "I'm going to the computing center tomorrow, of course I have to understand the subject first."

Then he opened the draft paper, and after opening it, he was ready to calculate, "By the way, how did you know that I want draft paper?"

Henry said as a matter of course: "The first law of mathematics and physics research, when you are reading a paper, if you suddenly look for something, you must be looking for scratch paper."

Lin Xiao: "...it seems reasonable, who said that?"

Henry smiled, "It's also called Bernard's first law."

"Okay." Lin Xiao shook his head with a smile, took out a pen from the side, pointed to a picture on the computer screen, and said, "Look at the coefficients of W- and W+, if A3 is used as the W boson Lateral momentum, we get the differential distribution of this function, isn’t there a problem?”

Henry looked at it and said: "Well, the differential distribution of the lateral momentum of the W boson? Under this ratio, there is a certain difference between the standard of the experimental data and our theoretical standard. Looking at the ratio of the image, it is... 2 %? But what's wrong with that?"

Such differences are inevitable. After all, one is an experiment and the other is a theory. Of course, there will be a gap.

Lin Xiao shook his head and said, "This difference can continue to be corrected."

"Revision?" Henry was taken aback: "2% is already very low, can it be revised?"

Lin Xiao didn't say much, and began to write on the draft paper.

[3/(16π)*(dσ^U)/(dpdydmν)...]

……

The purpose of their project is to help obtain more accurate predictions when measuring the mass of the W boson in the future.

The model in front of them is a part of their whole theory, that is, the differential distribution of the transverse momentum of the W boson. By comparing the theoretical model with the experimental data, if the error in it is reduced, it will help them to finalize the whole theory. contention.

And now there is a 2% error, which is really low, but it still shows something.

That is to say, there is still room for improvement in their theoretical model. If the theory can be improved and the theory is closer to the experimental results, then their future calculations will bring more perfect conclusions.

This is like a slight difference, a thousand miles, a small error, after countless steps, this error will be infinitely magnified, especially in high-energy physics, it is necessary to pay attention to differentiating each quantity. The 2% gap, if this method is finally applied to the measurement of the W boson mass, it will have a considerable impact on the result in the end.

Therefore, Lin Xiao is now going to modify their theoretical model to reduce this error, so as to continue to narrow the gap for the measurement of the W boson mass.

Seeing that Lin Xiao was writing more and more complicated mathematical formulas, the corners of Henry's mouth twitched. Sometimes it was difficult for him to understand what these mathematical geniuses were thinking. If he wanted to understand those complicated formulas, It took at least ten seconds, but Lin Xiao just wrote it out without any pause, as if he hadn't thought about it at all.

However, although he couldn't keep up, Henry was still watching from behind. He wanted to see how far Lin Xiao could reduce this error.

Just like that, Lin Xiao put the draft paper aside. After ten sheets of paper were used, Lin Xiao finally launched a completely new mathematical model.

Then, he stretched himself, opened Matlab, and entered his mathematical model into this mathematical software.

"nailed it?"

Henry asked.

"nailed it."

Lin Xiao smiled slightly, and then clicked the 'Export' button.

And as the result appeared, shock appeared on Henry's face.

Today's error--

0.01%!

How can it be? !

Chapter 182 discusses from the overall framework?

"Oh-la-vache!"

In Swen Sai's room, Swen Sai exclaimed.

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

It's just that 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 Svensey's shocked expression, Henry had a 'comfortable' feeling on his face. Since he himself was shocked, of course he also wanted to see how the professor was shocked.

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

Svensey glared at him angrily, "It's the same as what you said."

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

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

Lin Xiao then put the ten draft papers he had used up in front of Swen Sai from the side.

Swen Sai browsed it roughly. Of course, he didn't read it all. He just looked at Lin Xiao's train of thought and some important calculation processes. After that, he understood what Lin Xiao meant.

"Beautiful, well done."

Swen Sai admired, "With your help, it seems that our subject will not last long."

This is the role of a mathematical genius in their physics world, just take a look and be able to find out how to correct their mathematical models.

The original 2% error was directly reduced to 0.01%, a full 200 times the gap, which will bring great help to their future research on this topic. Based on this achievement, the second work will not be handed over directly to Lin Xiao Question, Swen Sai even started to consider giving up the first work to Lin Xiao, and then became the corresponding author himself.

Then think about it again, how many days has 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 have to do my best."

Svendall nodded with satisfaction: "It would be the best if everyone can think so."

Then he glanced at Henry beside him.

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

"You'd better finish your own thesis."

Svensey shook his head, too lazy to talk to Henry.

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

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

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

"Ok."

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

However, Lin Xiao did not start to rest, but took his calculation results and fell into deep thought in his mind.

Their purpose is to provide the necessary theoretical guidance for accurately extracting the W boson angle coefficient in the experimental analysis, and then through this point, directly point to the W boson to help measure its mass.

So, in addition to this direction, what method can they use to measure the mass of the W boson more accurately?

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

Angle factor is only one aspect, it is limited to one direction, but to achieve a more perfect result, he must discuss this issue from a higher level, or from the scope of the overall framework.

"The overall framework..."

Lin Xiao silently read these words in his heart.

The W boson, the weak force...

Finding a piece of paper from the side, he simply wrote a 'W' on it.

Suddenly, a thought came to his mind, the Higgs mechanism?

Higgs mechanism!

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

Let particles gain mass!

When you hear it this way, you know how awesome it is.

It is also for this reason that the Higgs particle that appears based on the Higgs mechanism is also called the God particle. After all, in the concept of Westerners, only God can create various substances and create quality.

And once human beings can master the Higgs particle, then human beings are equal to God. Of course, if human beings can really master the Higgs particle thoroughly, it must not be considered by people of their time.

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

Since the W boson needs to gain mass, it must be coupled 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 its actual implementation. Even Lin Xiao feels that it is far away.

"It's really challenging."

Lin Xiao sighed lightly.

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, just thinking about it in his mind for a moment, Lin Xiao refocused his attention on the manuscript in front of him.

Since there is a problem, then solve the problem, this is what he should do.

"continue."

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

And Henry in the back looked at Lin Xiao who was working so hard, and sighed, so, only such a person can reach the current situation, right?

……

Time passes quickly.

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

So when it came time to rest at night, 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, such as particle accelerators, astronomical telescopes and satellites in operation. Here, it is then provided to researchers for analysis.

In particular, relevant data generated by the Large Hadron Collider is also one of the main storage centers here.

And this time Lin Xiao and the others came here precisely to take advantage of its computing power. Of course, they can also perform calculations by accessing nodes in Paris, but since they are all here, they can use it directly on the spot. no problem.

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 by them, 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 is reduced by 2-4 times!"

A postdoctoral fellow looked at the final result and exclaimed.

Then, they all looked at Lin Xiao uncontrollably with the wooden pipes.

It was because he modified one of the mathematical models that immediately made their progress so great. As long as the error can be reduced to less than 3%, they will succeed!

But before their highest error was more than 10%.

This Chinese man is really a bit too scary, right?

Of course, the fact that the error can be reduced so much this time is also indispensable for their long-term revisions, but Lin Xiao's help still provides them with great help.

After all, the error ratio of their estimate this time is 6%, which has completely exceeded expectations.

After learning about this result, Lin Xiao also smiled slightly, but he still had some regrets. Although the model he modified reduced its own error by 200 times, the model itself did not account for the highest proportion in their entire theory. So the final calculated error is not directly reduced by the same multiple.

Of course, it is quite good to have such a result.
