"Strange?" Approaching, Yan brother looked at the computer screen for a while, his brow slightly wrinkled. "...It's really weird. Isn't the experiment we made is a collision of 1-10gev segments? How? Did you go up to 1tev?"

Said, Yan brothers cast a question of inquiry to Professor Grayer.

The conversion between tev and gev is 1:1000, which is equivalent to the particle beam in the tunnel of the collider. The energy of the collision has reached 1000gev. 6gev is enough to find the collision energy needed for the five quark state particles.

In order to find a particle located in the 6gev energy zone, the collision energy is above 1000gev. This is no longer a cannon to fight mosquitoes. It is simply a rocket hitting a fly.

However, when he heard Yan Xinjue’s doubts, Professor Grayer laughed and explained in a casual tone.

"I said, it is not a formal experiment to test the status of the track. As for why it is so big, you have to understand that cern loves to get this new toy. If it is not the budget of this experiment is limited, they are even prepared to give You guys show off the collision above the 10tev energy zone."

To put it bluntly, it is to show off.

And it is still the kind of display of red fruit.

Imagine that theoretical physicists and high-energy physics labs around the world are focusing on it. Do not take advantage of this opportunity to show off a hand, is it not a few hundred million to spend the expansion of the track?

Do not let the colliders turn into the clusters of particles inside, how to let others know how powerful their machines are?

However, Cern does have the capital to show off. It is said that in the extreme case, the Hadron Collider after the expansion can even achieve a 14tev collision test. In other words, each particle that runs in orbit will carry 7tev of energy.

How terrible is this energy?

In many cases, this energy unit (according to the mass-energy conversion formula) is also used to describe the mass of a particle. For example, the mass of a hydrogen atom is about 1 gev, and the higgs particle found in 12 years is 125 gev.

Horizontally comparing the peers, the limit of the Shangzheng electron-positron collider is about 5gev, which is an order of magnitude difference from the energy unit of tev.

If you want to catch up with this energy unit, you can only expect the completion of the cepc of Qindao, but that is also a matter of ten years.

"...I don't mean that the experimental section is strange," Lu Zhou's fingers almost poked on the computer screen. "You didn't notice it? There is an unusual impact here near the 750gev."

"This is not a collision phenomenon. It is just a single two-photon signal. But it is a bit strange why it appears in the 750gev energy zone." Professor Grayer touched his chin. "But strangely strange, this is not uncommon." We can always observe some special signals on the atlas detector, but the data reflected in the statistical image may be just a 'murmur'."

"Is this situation very common?" Staring at the abnormal point on the screen, Lu Zhou could not help but ask.

"It's quite common," Yan Shixiong nodded. "All the signals generated by the proton beam collision are less than 1%. So we usually guess the conclusion, and then verify it through experiments. If you stay here often, I will get used to it."

High-energy physics itself is a very metaphysical thing.

Because it exists below the atomic level, it cannot be "directly observed", so in order to determine the true existence of a particle, it will involve a very important indicator confidence.

This is a statistical concept.

In high-energy physics experiments, 3 times the standard deviation is called “signs”, 3 times is called “evidence”, and more than 5 times can be called “discovery”. Although the words "breakthrough progress" and "significant discovery" often appear in the news, most of the cases are just "signs."

Based on this accepted theory, when the confidence reaches 3 sigma, it can barely be counted as a "sign".

A temporary characteristic peak does not indicate anything.

This particle can only be confirmed by continuously repeating the experiment and repeatedly observing a particle on different detectors and different colliders so that the confidence of the particle on multiple detectors is above 5 sigma. For "discovery."

When I heard Yan Shixiong say this, Lu Zhou did not say anything.

Soon, the experiment continued.

A series of green dots spread out on the image, and most of the points are concentrated in the area below the 125gev boundary.

However, the point that Lu Zhou’s heart appeared for the 750gev was still too much, and the attention was still pinned on the energy zone.

Then at this moment, suddenly another point jumped in the 750gev energy zone.

At this moment, Lu Zhou suddenly felt a move, looking at Professor Greer next to him: "What about the data on the cms detector?"

There are many detectors in one orbit, and the two detectors atlas and cms are the most sensitive and even used to look for dark matter.

There is a very simple way to test whether the anomaly he found is an illusion, that is, the same phenomenon is observed by both detectors at the same time.

When he heard the question of Lu Zhou, Professor Grayer squinted a little and answered with some doubts.

"...the data collected by the cms detector is the lab upstairs. If you are curious, wait a while and the experiment is over. I can take you there, but I can't go now."

Lu Zhou then asked: "Will the impact data measured by these test runs be recorded?"

Professor Grayer nodded: "Generally, it will be archived, but there is not much reference value. I can give you a copy if you need it. It is not a secret content anyway. But I have to remind you that this is not Public experimental data, if you want to quote in the paper is impossible."

Standing next to him, Yan Shisi curiously asked: "What did you find out?"

Lu Zhou thought about it and finally insisted on his own point of view. He said: "I always feel that the data of the 750gev energy zone is a bit problematic. Even if it is explained from a statistical point of view, this obvious convexity is described as random. The incident always feels a little far-fetched."

Yan Shixiong joked: "From the perspective of a mathematician?"

Lu Zhou: "That's right."

Yan Shixiong sighed and said: "I know that your research direction is mathematical physics, but I have to remind you that although mathematics is an important tool for studying theoretical physics, not all physical phenomena must conform to mathematical laws. From theoretical physics From a learning point of view, the number of 750gev... is really too heavy. It should be known that the Higgs particle is only 125gev. Maybe you think you found a new particle, but in my opinion it is just a two-photon. The signal may not even have a collision at all."

After taking a picture of Lu Zhou’s shoulder, Yan’s brother continued, “Don’t entangle the energy area after 10gev. We are looking for the five quark state particles. If it is because of obsessive-compulsive disorder, you can rest assured that in the experiment for a while. You must never see the 750gev phenomenon again."
