"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
Soon, the experiment continued.
However, CERN does have the capital to show off. It is said that under extreme conditions, the expanded hadron collider can even achieve a 14TeV collision experiment. In other words, each particle running in the orbit will carry 7 TeV of energy.
As he said that, Senior Brother Yan cast a questioning look at Professor Greer.
"This is not called an impact phenomenon. This is just a single two-photon signal. However, it is a bit strange why it appears in the 750GeV energy region." Professor Greer touched his chin, "But it is strange, and this situation is not uncommon. , we can always observe some special signals on the ATLAS detector, but the data reflected in the statistical images may be just a 'noise'."
Then at this moment, another point suddenly jumped to the 750GeV energy region.
The conversion between TeV and GeV is 1:1000, which is equivalent to the particle beam in the collider tunnel. The energy of the collision has reached 1000GeV. The collision energy required to find pentaquark particles is 6 GeV.
Patting Lu Zhou's shoulder, Senior Brother Yan continued, "Don't worry about the energy region after 10 GeV. What we are looking for this time are pentaquark particles. If it is because of obsessive-compulsive disorder, you can rest assured that we will conduct experiments in a while , you will definitely never see the 750GeV phenomenon again.”
Then at this moment, another point suddenly jumped to the 750GeV energy region.
To put it bluntly, it’s just showing off.
Since existence below the atomic level cannot be "directly observed", in order to determine the true existence of a particle, a very important indicator - confidence is involved.
Upon hearing Lu Zhou's question, Professor Greer was slightly stunned and answered with a somewhat puzzled expression.
In high-energy physics experiments, anything less than 3 times the standard deviation is called a "sign," more than 3 times is called "evidence," and more than 5 times a standard deviation is called a "discovery." Although words such as "breakthrough progress" and "major discovery" often appear in the news, in fact, most situations are just "signs."
In order to find a particle located in the 6GeV energy region, the collision energy is increased to more than 1000GeV. This is no longer a cannon to kill mosquitoes, but a rocket to kill flies.
Imagine that theoretical physicists and high-energy physics laboratories around the world are focusing their attention here. If we don't take this opportunity to show off, wouldn't it be that the billions spent on rail expansion have been wasted
Upon hearing Lu Zhou's question, Professor Greer was slightly stunned and answered with a somewhat puzzled expression.
Professor Greer nodded: "Generally speaking, it will be archived, but it doesn't have much reference value. I can make a copy for you if you need it. It's not confidential anyway. But I have to remind you that this kind of future It is impossible for you to cite public experimental data in your paper."
After hearing what Senior Brother Yan said, Lu Zhou said nothing more.
Lu Zhou thought for a while, and finally insisted on his point of view, and said: "I always feel that there is something wrong with the data in the 750GeV energy region. Even if it is explained from a statistical perspective, this obvious bulge is described as random. The incident always feels a bit far-fetched.”
However, upon hearing Yan Xinjue's question, Professor Greer laughed and explained in a nonchalant tone.
"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
A series of green dots are spread out densely on the image, and most of the dots are concentrated in the area below the 125GeV dividing line.
"I said, the current situation on the test track is not a formal experiment. As for why it is so big, you have to understand CERN's love for getting this new toy. If it weren't for the limited budget of this experiment, they were even prepared to give it to You colleagues, please show us the collisions above the 10TeV energy region.”
After hearing what Senior Brother Yan said, Lu Zhou said nothing more.
There is a very simple way to test whether the anomaly he discovered is an illusion, that is, the same phenomenon is observed by two detectors at the same time.

If you want to catch up with this energy unit, you can only wait for the completion of Qindao's CEPC, but that will only happen ten years later.
To put it bluntly, it’s just showing off.
If you don't let the collider spin and blast the particle clusters inside, how can you let others know how awesome your machine is
There are many detectors on an orbit, among which ATLAS and CMS are the most sensitive detectors and are even used to search for dark matter.

And it's still showing off naked.
"It's quite common," Senior Brother Yan nodded. "We understand less than 1% of all the signals generated by proton beam collisions. So we usually speculate on the conclusions and then verify them through experiments. If you stay here often You’ll get used to it.”
Only by continuously repeating experiments and observing a certain particle multiple times on different detectors and different colliders, so that the confidence level of this particle on multiple detectors reaches above 5sigma, can this particle be confirmed for "discovery".
However, Lu Zhou still couldn't let go of the point where 750 GeV appeared, and his attention was still limited to that energy region.
How terrifying is this energy

Lu Zhou then asked: "Will the impact data measured during these test runs be recorded?"
"...The data collected by the CMS detector is the responsibility of the laboratory upstairs. If you are curious, I can take you there to have a look after the experiment is over, but I can't leave now."

If we compare it horizontally with its peers, the limit of the Beijing Electron Positron Collider is probably around 5GeV, which is an entire order of magnitude lower than the energy unit of TeV.
"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
In many cases, this energy unit (according to the mass-energy conversion formula) is also used to describe the mass of particles. For example, the mass of a hydrogen atom is about 1 GeV, and the Higgs particle discovered in 2012 is 125 GeV.

Then at this moment, another point suddenly jumped to the 750GeV energy region.

And it's still showing off naked.
Senior Brother Yan sighed and said: "I know 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 comply with mathematical laws. From theoretical physics From a scientific point of view, the number 750GeV... is too heavy. You must know that the Higgs particle is only 125GeV. Maybe you think you have discovered a new particle, but in my opinion it is just a two-photon signal. , there may even be no collision at all.”

Standing nearby, Senior Brother Yan asked curiously: "What exactly did you find?"
Professor Greer nodded: "Generally speaking, it will be archived, but it doesn't have much reference value. I can make a copy for you if you need it. It's not confidential anyway. But I have to remind you that this kind of future It is impossible for you to cite public experimental data in your paper."

In many cases, this energy unit (according to the mass-energy conversion formula) is also used to describe the mass of particles. For example, the mass of a hydrogen atom is about 1 GeV, and the Higgs particle discovered in 2012 is 125 GeV.
And it's still showing off naked.
"...The data collected by the CMS detector is the responsibility of the laboratory upstairs. If you are curious, I can take you there to have a look after the experiment is over, but I can't leave now."
If you don't let the collider spin and blast the particle clusters inside, how can you let others know how awesome your machine is
In order to find a particle located in the 6GeV energy region, the collision energy is increased to more than 1000GeV. This is no longer a cannon to kill mosquitoes, but a rocket to kill flies.
Lu Zhou then asked: "Will the impact data measured during these test runs be recorded?"

Imagine that theoretical physicists and high-energy physics laboratories around the world are focusing their attention here. If we don't take this opportunity to show off, wouldn't it be that the billions spent on rail expansion have been wasted
"...The data collected by the CMS detector is the responsibility of the laboratory upstairs. If you are curious, I can take you there to have a look after the experiment is over, but I can't leave now."
Professor Greer nodded: "Generally speaking, it will be archived, but it doesn't have much reference value. I can make a copy for you if you need it. It's not confidential anyway. But I have to remind you that this kind of future It is impossible for you to cite public experimental data in your paper."
Then at this moment, another point suddenly jumped to the 750GeV energy region.
"I said, the current situation on the test track is not a formal experiment. As for why it is so big, you have to understand CERN's love for getting this new toy. If it weren't for the limited budget of this experiment, they were even prepared to give it to You colleagues, please show us the collisions above the 10TeV energy region.”
And it's still showing off naked.
"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
"This is not called an impact phenomenon. This is just a single two-photon signal. However, it is a bit strange why it appears in the 750GeV energy region." Professor Greer touched his chin, "But it is strange, and this situation is not uncommon. , we can always observe some special signals on the ATLAS detector, but the data reflected in the statistical images may be just a 'noise'."

Standing nearby, Senior Brother Yan asked curiously: "What exactly did you find?"
In order to find a particle located in the 6GeV energy region, the collision energy is increased to more than 1000GeV. This is no longer a cannon to kill mosquitoes, but a rocket to kill flies.
At this moment, Lu Zhou suddenly felt something in his heart. He looked at Professor Greer next to him and asked, "Where is the data on the CMS detector?"
Standing nearby, Senior Brother Yan asked curiously: "What exactly did you find?"
Only by continuously repeating experiments and observing a certain particle multiple times on different detectors and different colliders, so that the confidence level of this particle on multiple detectors reaches above 5sigma, can this particle be confirmed for "discovery".
Lu Zhou thought for a while, and finally insisted on his point of view, and said: "I always feel that there is something wrong with the data in the 750GeV energy region. Even if it is explained from a statistical perspective, this obvious bulge is described as random. The incident always feels a bit far-fetched.”
Then at this moment, another point suddenly jumped to the 750GeV energy region.
High energy physics itself is a very mysterious thing.
Senior Brother Yan sighed and said: "I know 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 comply with mathematical laws. From theoretical physics From a scientific point of view, the number 750GeV... is too heavy. You must know that the Higgs particle is only 125GeV. Maybe you think you have discovered a new particle, but in my opinion it is just a two-photon signal. , there may even be no collision at all.”
Lu Zhou thought for a while, and finally insisted on his point of view, and said: "I always feel that there is something wrong with the data in the 750GeV energy region. Even if it is explained from a statistical perspective, this obvious bulge is described as random. The incident always feels a bit far-fetched.”
Then at this moment, another point suddenly jumped to the 750GeV energy region.
If we compare it horizontally with its peers, the limit of the Beijing Electron Positron Collider is probably around 5GeV, which is an entire order of magnitude lower than the energy unit of TeV.
Senior Brother Yan joked: "From the perspective of a mathematician?"
"...I don't mean that the energy range of the experiment is strange," Lu Zhou's finger almost touched the computer screen, "Didn't any of you notice? There is an abnormal impact phenomenon here near 750 GeV."
At this moment, Lu Zhou suddenly felt something in his heart. He looked at Professor Greer next to him and asked, "Where is the data on the CMS detector?"
Standing nearby, Senior Brother Yan asked curiously: "What exactly did you find?"
How terrifying is this energy
"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
If you want to catch up with this energy unit, you can only wait for the completion of Qindao's CEPC, but that will only happen ten years later.
There is a very simple way to test whether the anomaly he discovered is an illusion, that is, the same phenomenon is observed by two detectors at the same time.
Upon hearing Lu Zhou's question, Professor Greer was slightly stunned and answered with a somewhat puzzled expression.
Lu Zhou: "That's right."
Lu Zhou thought for a while, and finally insisted on his point of view, and said: "I always feel that there is something wrong with the data in the 750GeV energy region. Even if it is explained from a statistical perspective, this obvious bulge is described as random. The incident always feels a bit far-fetched.”
Soon, the experiment continued.
Patting Lu Zhou's shoulder, Senior Brother Yan continued, "Don't worry about the energy region after 10 GeV. What we are looking for this time are pentaquark particles. If it is because of obsessive-compulsive disorder, you can rest assured that we will conduct experiments in a while , you will definitely never see the 750GeV phenomenon again.”
Senior Brother Yan sighed and said: "I know 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 comply with mathematical laws. From theoretical physics From a scientific point of view, the number 750GeV... is too heavy. You must know that the Higgs particle is only 125GeV. Maybe you think you have discovered a new particle, but in my opinion it is just a two-photon signal. , there may even be no collision at all.”
The conversion between TeV and GeV is 1:1000, which is equivalent to the particle beam in the collider tunnel. The energy of the collision has reached 1000GeV. The collision energy required to find pentaquark particles is 6 GeV.
"It's quite common," Senior Brother Yan nodded. "We understand less than 1% of all the signals generated by proton beam collisions. So we usually speculate on the conclusions and then verify them through experiments. If you stay here often You’ll get used to it.”
"Strange?" Coming closer, Senior Brother Yan stared at the computer screen for a while, frowning slightly, "...it's indeed quite strange. Isn't the experiment we did a collision in the 1-10GeV energy range? How come the data are all Did you go to 1TeV?"
High energy physics itself is a very mysterious thing.
To put it bluntly, it’s just showing off.
