“Strange?” Approaching, Yan Senior Brother stared 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 the 1-10GeV segment?” Is the data going to 1TeV?”

Speaking, Yan Senior Brother cast a sight on the Glenel Professor.

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

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

However, when I heard Yan Xinjue’s question, Greer Professor haha ​​laughed, 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 CERN’s love for getting 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 collisions 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 all of World’s theoretical Physics and high-energy physics labs are focused 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 extended Hadron Collider can even perform the 14TeV collision test. That is to say, each particle running in the orbit will carry the energy of 7TeV.

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 the particle. For example, the mass of 1 hydrogen atoms is about 1GeV, and the Higgs particle discovered by 12 is 125GeV.

Horizontally contrasting peers, the limit of the Shangzheng electron-positron collider is about the same as the 5GeV, which is an order of magnitude worse than the energy unit of TeV.

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

“…I don’t mean the experimental section is strange,” Lu Zhou’s fingers almost poked on the computer screen. “Did you not notice? There is an unusual impact here near 750GeV.”

“It’s not a collision phenomenon. It’s just a single two-photon signal, but it’s a bit strange why it appears in the 750GeV energy zone.” Greer Professor touch the 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?” Lu Zhou couldn’t help but stare at the anomaly on the screen.

“It’s quite common,” Yan Senior Brother nodded, “All signals generated by proton beam collisions are less than 1%. So we usually guess the conclusions, and then verify by experiment, 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, the 3 standard deviation is hereinafter referred to as “signs”, 3 times is referred to as “evidence”, and 5 times or more can be referred to as “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 3sigma, it can barely be counted as a “sign”.

A temporary characteristic peak does not indicate anything.

This particle can only be confirmed by 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 5sigma. For “discovery.”

I heard that the strict Senior Brother said so, Lu Zhou did not say anything.

Soon, the experiment continued.

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

However, Lu Zhou’s mind was still a bit uncomfortable with the point where 750GeV appeared, and attention was still pinned on the energy zone.

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

Just then, Lu Zhou suddenly felt a move, and the Greer Professor next to look at asked: “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 find 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 Lu Zhou’s question, the Greer Professor squinted slightly and replied with a puzzled expression.

“…the data collected by the CMS detector is responsible for the laboratory upstairs. If you are curious, wait a while, the experiment is over, I can take you there, but I can’t walk now.”

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

Greer Professor 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 confidential content anyway. But I have to remind you that this undisclosed Experimental data, if you want to quote in thesis is impossible.”

Standing next to it, Yan Senior Brother curiously asked: “What did you find?”

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 bump is described as random. The incident always feels a little far-fetched.”

Strict Senior Brother play with with a smile : “From the perspective of a mathematics home?”

Lu Zhou: “That’s right.”

Yan Senior Brother sighed said: “I know that your research direction is mathematics physics, but I have to remind you that although mathematics is an important tool for studying theoretical physics, not all physics phenomena must conform to the laws of mathematics. From the theory of Physics In perspective, the number of 750GeV… is really too heavy, knowing 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 signal. There may not even be a collision at all.”

After taking a shot of Lu Zhou’s shoulder, Yan Senior Brother continued, “Don’t entangle the energy zone after 10GeV. We are looking for five quark particles. If it is because of obsessive-compulsive disorder, you can rest assured that for a while. In the middle, you will never see the 750GeV phenomenon anymore.”
