Yan Xinjue was right. After the experiment began, the emitted particle beam was stable under 5GeV. The signal captured by ATLAS is concentrated only between 1GeV - 10GeV.
Occasionally, a point appears outside the 10GeV range, but they will not deviate much.
Naturally, no data from the 750 GeV was produced.
However, Lu Zhou was still unsure.
The experiment lasted all day.
Around 12am, there was a cheer at CERN headquarters.
From the data received from the various detectors, the confidence level of the pentaquark exceeds five sigma. This means that an "invention" has been made!
Although everyone expected this, people were still excited.
In general, quarks divided into colliders are "quark-antiquark" pairs similar to K mesons and "three quark state" mesons consisting of protons and neutrons. As for the state of a single quark, since quarks are bound by the strong force of the color charge, a single quark state particle is not allowed to exist.
However, quantum chromodynamics does not prohibit the existence of single states such as "tetraquark" and "pentaquark".
For years, the main particle physics laboratory has been searching for that "singular state.
If these people are not found, it may prove a gap in the standard model. So, quantum chromodynamics may not be correct.
However, once this singular state is discovered, the entire theoretical physics community will be greatly relieved!
After the second day of the experiment, CERN invited reporters and held a high-profile press conference.
In front of media reporters, a CERN spokesperson announced the news in an excited tone.
“... We've managed to find the pentaquark particle. This is another big win for the standard model! ”
Not surprisingly, the discovery of pentaquarks will be the most significant result of this year's pentaquark research.
The CERN conference ended amid applause. This was followed by many articles on research findings.
However, for physicists, the real work is just beginning.
To better reveal the physical properties of pentaquark particles, the LHCb International Cooperation Group assigned the task to researchers in different countries to perform a full spectrum analysis on the newly discovered particles.
Professor Lu Shenjian was also involved in this work.
However, this task is not as time intensive as the calculation of B1 data.
Later, Lu Zhou heard from Yan Xinjue that this task was different from the others. Each “full spectrum analysis” paper will be signed by all researchers.
Too many co-authors will weaken the content of the thesis.
"Thousands of signatures ... My name won't even be visible. It's very motivating. "
“That's how it works for CERN. That's why I'm not suggesting you work here. No one can even win a Nobel Prize"." Yan Xinjuie said. He yawned and put down the pen before asking, "Do you want to play billiards tonight?"
Lu Zhou thought before shaking his head, "No, thank you, I'm fine. I still have to go to Professor Grayer's office. "
Last time after the experiment, Professor Grayer promised that he would take the time to help Lu Zhou sort out the experimental data.
Just now, Lu Zhou received an email from Professor Grayer, saying that the data had been sorted out and went to his office by USB.
It didn't take long to copy the data, but Lu Zhou wanted to analyze the data on the same night.
After all, he had to help Professor Lu's project during the day. He's only free during weekends and evenings.
Yan Xinjue knew what Lu Zhou was going to do and he said, "Don't tell me that about it."
Lu Zhou, "You can guess."
Yan Xinjue had a defeated look as she sighed and said, "Well, I admire your commitment, but you know that you did a useless job, right?"
Lu Zhou smiled and asked, "How do you know it's useless without doing work?"
Lu Zhou is like this. He is stubborn in mathematics and physics.
Currently, he is very interested in the characteristic peak of the 750 GeV.
Although Yan Xinjue and Professor Grayer conveyed that the peak might be nothing more than a two-photon signal and it would be ridiculous for a particle to carry that much energy, Lu Zhou disagreed.
The 750 GeV does seem a bit heavy, but it's still possible.
Lu Zhou believed that investigating the borders of any discipline required imagination.
Although the two chromodynamic quantum experts tried to persuade him, it was of no use to Lu Zhou.
How did quantum chromodynamics evolve?
Was it not developed by diverting from "common sense"?
It didn't matter if Lu Zhou was wrong because failure was part of success.
After dinner, Lu Zhou walked into the building R2 1 . Professor Grayer was waiting for him in his office.+
“Data you want is on this USB, including data from CMS detector. Honestly, this data is pretty useless. We only did the test for an hour, so it has no useful experimental results. "
Lu Zhou, "Thank you ... I just want to satisfy my curiosity. I'll still try. "
"Curious?" Said Professor Grayer. He smiled and gave her a look of encouragement as he said, "Then good luck."
