"Is the collision experiment related to the time machine?"

"If an accident happens to the control experiment, will the resulting energy wave wipe out Switzerland?"

"..."

Listening to the strange questions asked by the reporters, Zhao Yi felt like watching a comedy. The foreign reporters are really humorous. They asked these questions. It might be very easy to go back and write reports. It is the content of mass entertainment.

at the same time.

Ruan Wenye also began to explain his work, "From today onwards, everyone has to adjust their time. We need to wait to receive the data and be ready to work at any time."

"I will assign the specific work assignment after tomorrow's meeting."

His so-called 'tomorrow's meeting' is the distribution of test experiments, data analysis and verification, and each participating team will be assigned to work.

Because the workload of data analysis is huge enough, even the discriminated Caltech team will be assigned a certain job, but it will definitely be targeted during acceptance.

There is no other way for the Caltech team. It is already very good that they can participate in the work, and it is only natural that they are targeted and suspected.

There is no room for error in the research work of physics.

After the meeting, it was obvious that the atmosphere became tense, not just the academic atmosphere, but the whole town became tense, and some troops also moved in.

The town is under martial law.

From then on, anyone who wants to enter the town will be subject to strict interrogation. People inside need to apply for a pass if they want to go out, not to mention the tunnel entry and exit points of the collider. Ordinary people will be persuaded to leave as long as they approach .

The day of the experiment.

Zhao Yi and Ruan Wenye share a car. He will dive underground to get close to the collision experiment. He is actually a little reluctant. The particle collision experiment will produce high radiation, which may cause damage to the body. .

Although theoretically there will be no radiation that would cause harm to the human body leaked from the outside of the collider, but he is not a physicist who is willing to dedicate himself to science.

But, no way!

Each team must have several people participate in the experiment at close range, and Zhao Yi has made great contributions to the team in the verification work in D area, and he was dragged here by Ruan Wenye.

Ruan Wenye felt that a genius like Zhao Yi should devote himself to the research of physics, and let him realize how attractive it is to study the mysteries of physics.

Ok.

Anyway, Zhao Yi couldn't figure out what is so attractive about the close-contact collision experiment.

……

When Zhao Yi came to the place where he worked underground, he relaxed a little.

It's no different from the outside here, except that there are workshops and laboratories underground, and there are all kinds of equipment everywhere. Some people are here for the first time, so they just walk around.

This is an underground research center, mainly responsible for observing and collecting data.

Different workshops and laboratories collect different data.

Zhao Yi walked into a workshop and saw a bearded man looking at the computer screen, while he was leisurely tiptoeing.

"Zhao Yi!"

The bearded man turned his head to see Zhao Yi in surprise.

Only then did Zhao Yi recognize that it was the strong Nordic man who imagined him to be a physics genius at the academic report meeting.

"Edmir." The bearded man introduced himself, and stood up to get a chair for Zhao Yi, "What would you like to drink?"

"Cafe!"

Zhao Yi turned his head and looked over, only to find that the facilities in the laboratory are really complete, and there are all kinds of coffee next to the coffee machine. Obviously, the bearded man is a person who likes to drink coffee very much.

"Actually, I prefer whiskey, but alcohol is not allowed here." Edmir's tone was regretful. He pointed to the computer screen and said, "Look at my work, how monotonous, I need to face these every day."

Zhao Yi looked at the computer screen, and found that there were a lot of messy things on it, and he couldn't describe what they were. It was like a child scribbling on paper. There were lines and spots, and some places were dark. In some places the color is light.

"Data!"

Edmir explained, "That's the data map of the decay of experimental particles. Look at it, how complicated it is! My job is to summarize these data, analyze how they decay, and make records."

"However, I always feel that this work is meaningless, because some teams will make more detailed analysis, I just do the basic work, and the results are just for reference..."

Edmir complained.

Looking at the complicated graphics on the screen, Zhao Yi also felt a little pain in his forehead. He understood Edmir a little bit.

He suddenly asked suspiciously, "Is this work related to the Higgs particle?"

"It seems that you are a rookie in physics as others have said." Edmire explained with a smile, "The most important thing to study the Higgs particle is to study the particle's behavior during the collision experiment. Decay data, because in theory, after the Higgs particle appears, it will decay in a very short time..."

Edmir explained in detail.

Zhao Yi kept nodding his head as he listened, as if he was very serious, when a flash of inspiration suddenly appeared in his mind.

[Look at the data graph in front of you, the connection with the Higgs particle! 】

["Relational Law"! 】

[It takes [-] energy points to use "Relationship Rate", do you want to use it? 】

really work?

Zhao Yi suddenly felt his eyes light up. He didn't expect that "Relationship Rate" could be used in this way, so he immediately chose to use it.

Chapter 253 This is cheating!

"Relevance Rate" only feeds back a picture location information.

After receiving the message, Zhao Yi continued to nod while listening to Edmir's words, and pointed to a small dot on the screen when he found space and asked, "What is this?"

"Which one?" There are too many dots and lines on the screen, and I can't be sure which one I'm talking about.

"Enlarge the picture."

Zhao Yi said something reminding.

Edmir enlarged the position just now, and there are still many points and lines on the screen, but the distance is relatively larger.

Zhao Yi simply moved the mouse and placed it on a bright spot on the screen, "This is what I'm talking about."

"this?"

Edmir was a little puzzled and said, "It's a photon emitted by a particle. It's full of things like this. The product of particle collision and decay will slow down under the action of a magnetic field in the detection, thus releasing photons. Why do you Ask this? This point is no different from the others."

He couldn't see it anyway.

There are too many dots and lines on the screen, and the position Zhao Yi pointed to looks no different from other dots.

Edmir continued, "Many of the dots on this are the same. It can only form a small dot, indicating that the energy of the photon released is very small. There are many, many such dots, and they should be very small particles. product of."

"Maybe it's decay, maybe it's just because of the deceleration, or maybe it's just environmental influences. Even some sounds in the pipeline may cause the particles to vibrate."

Zhao Yi listened carefully.

Although Edmir spoke very casually, the content revealed in the true words was what he should learn and understand.

He nodded and said, "But it could also be a product of Higgs decay, right?"

"of course."

Edmir said with a smile on his face, "If you want to find the Higgs particle, you must study these very small points. Only they may be related to the Higgs particle."

"However, my work does not need to look for any Higgs particles. It is too difficult. Look at this picture, how many small dots are there, and each small dot needs to be carefully calculated to know What does it represent, even if there is a slight deviation, it will lead to wrong results."

"The most important thing is that even if your calculations are completely correct, the conclusion may be wrong."

"To be honest, I have also studied the Higgs particle. Anyone who works here hopes to find the God particle, but that is really too difficult. With the current performance of the collider, it is almost impossible to do it. .”

"Why?" Zhao Yi asked suspiciously, frowning.

"Because there are too few Higgs particles." Edmir laughed, "We assume that the Higgs particles exist, but according to the predictions of the particle model, the particle collision experiments we have done may only produce Dozens, a few, maybe none at all.”

"With this little data, it is impossible to find the Higgs particle, because the products of its decay do not have much influence in every mass interval."

"That's not even as good as an unexpected sound vibration."

Zhao Yi thought about it and understood.

Recently, he has learned a lot about the Higgs particle, the simplest one is how the Higgs particle is formed.

To understand the Higgs particle, you must first know the Higgs field. The central idea of ​​the Higgs field is that even in its lowest energy state, space is by no means empty.

Particles traveling through space will more or less interact with the Higgs field, which causes the particles to have a "sticky" characteristic when they move, that is, mass.

The W and Z bosons gained their mass through some kind of interaction with this field.

Fermions gain mass through another interaction.

Since the Higgs field carries no net charge or color charge, photons and gluons don't interact with it at all, so it still has no mass.

The Higgs particle can be understood as the shock and ripples of the Higgs field, just like in a vacuum, through powerful means to make it produce something with mass or detectable, it sounds like something out of nothing, but the fact is that Indeed.

So some people say that the study of the Higgs particle can even explain the origin of the universe.

Even from a theoretical point of view, generating the Higgs particle is not easy.

That's why Edmir said that in the collision experiment, the number of Higgs particles is too small, so small that there may be none, and even if there are, it is almost impossible to be detected.

After Zhao Yi realized it, he suddenly found that his luck was really good. Looking at a computer picture, he could find a light spot related to the Higgs particle.

"Mr. Edmir, can you change the picture, I'll take another look." Zhao Yi asked with some expectation.

"of course can."

Edmir started to operate the computer, and by the way, "Call me Jill, I like to be called by my name, Mr. Edmir is too outlandish."

"Okay, Jill."

Edmir immediately changed the pictures. He searched them one by one, and showed Zhao Yi the picture he admired the most, "Look at this one, the most dense one."

The picture has a lot of dots and lines, and one very thick line, more than three times denser than the original picture.

"What is this?" Zhao Yi asked, pointing at the thick line.

Edmir explained, "It's a bunch of particles combined, which is very valuable for research. If I zoom in..." He manipulated the screen to zoom in, and saw that the thick lines were a bunch of lines combined He continued proudly, "I was the first to discover this thick line, and I must have been of great research value at that time. There are many teams who want to get the information in advance, but before the end of the official meeting, other It is against the regulations to disclose the information, so I refused all of them, and they can only come to me if they want to see it.”

"I haven't been so popular in the past few years. An Englishman even sent me a few cases of wine. I accepted it, but I still didn't give him the information, hahahaha..."

Edmir couldn't help laughing out loud.

Zhao Yi was very funny.

Receive gifts, do nothing?This guy definitely has some bad tastes, no wonder no one came to the lab at all, he must have something wrong with him.

Of course.

That has nothing to do with Zhao Yi, at least he thinks Edmir is very good, he explained a lot of things to himself for free, and even checked the information for himself, and he gained a lot.

The harvest just now is that he knows that the Higgs particles are indeed very few. He spent nearly ten learning coins, followed Edmir to change pictures, and used "Correlation Rate" continuously, but did not get any feedback at all. In other words, A dozen pictures in a row have nothing to do with the Higgs particle.

So as Edmir said, the Higgs particle is so rare that it is really impossible to detect it.

"But I've found out?"

"I can determine where there are Higgs particle decay products, and based on the data at that location, I can calculate some properties of the Higgs particle."

"According to the properties of the Higgs particle, find out other decay products of the Higgs particle from a large amount of data..."

"But how to prove it?"

Although no formal attempt has been made, Zhao Yi does not think that "Contact Rate" can simply solve this problem.

The key is the condition!

However, there is a way to do what to do next. After performing detailed calculations on the properties of the Higgs particle, and collecting enough data and supplementing enough conditions, you can find out the evidence that proves the existence of the Higgs particle. method.

……

Although what to do is already on the surface, it is very difficult to do it. The first thing to do is to find out something related to the Higgs particle. It is best to find a few pairs of photons and study their momentum , to analyze the mass interval where the Higgs particle is located.

This is based on energy conservation, and the momentum of the scattered photon after decay is used to calculate the particle properties before decay.

The decay rate of the Higgs particle is very fast, and its decay is full of uncertainty. When the decay product passes through the detector, it will emit photons, so it is necessary to study the emitted photons to study the decay particles before.

What can be done now is to look for the photons related to the decay. The other decay products found have a little reference value, but because other substances are not sure what they will be, it is very difficult to calculate.

So it can only be photons.

For the next whole day, Zhao Yu would stay in Edmir's workshop when he was free. He would chat with Edmir occasionally, and most of the time he would look at the pictures on the computer.

Edmir seemed to be a rare person with him, and he seemed very happy. He told Zhao Yi how to change the pictures, but at the same time he was a little puzzled, "Are you doing data analysis? These pictures have been analyzed many times. If you want relevant information, I can help you find it.”

"Thank you in advance then."
