Yan Xinjue was right. After the experiment officially began, the particle beam basically stabilized below 5 GeV. The signals captured by the ATLAS detector were basically concentrated in the energy range of 1-10 GeV.
Occasionally, there were one or two exceptions that appeared outside the upper limit of the 10 GeV energy zone, but it was not too far off.
Under these circumstances, there would naturally not be 750 GeV data.
However, this result did not convince Lu Zhou, who believed that there must be something in the 750 GeV energy zone.
The experiment lasted for an entire day.
At around 12 o 'clock in the morning, the CERN headquarters dozens of kilometers away burst into cheers.
From the feedback data from the various detectors, the pentaquark particle's confidence level had exceeded 5 sigma. All the evidence pointed to the discovery of the pentaquark particle!
Although everyone had already expected this, those speculations were far less exciting than seeing it happen for real.
Generally speaking, the quarks split in the collider would either form a "quark-antiquark" pair similar to the K meson and pi meson, or they would form a "triquark state" such as the proton and neutron state. As for the single quark state, because the quark was bound by the strong force of the color charge, the single quark state was not allowed to exist.
However, quantum chromodynamics did not prohibit the existence of strange states such as the "tetraquark state" and "pentaquark state".
Over the years, major particle physics laboratories had been searching for these "strange states" on various colliders.
If these strange states were not discovered, it would prove that there might be loopholes in the standard model, and quantum chromodynamics might not be correct.
However, once these strange states were discovered, it would greatly boost the confidence of the entire theoretical physics community!
CERN could not wait to send invitations to the waiting reporters in Geneva the day after the experiment ended. They held an extremely high-profile press conference.
The CERN spokesperson stood in front of the media and announced the news in an excited tone.
"… We have successfully discovered the pentaquark particle. This is another great victory for the standard model! We are once again convinced that the path we chose is correct! "
The discovery of the pentaquark particle would become the most important research result of the year, overshadowing all other research results.
CERN's press conference ended amidst the applause. Immediately afterward, a large number of media outlets reported on this discovery.
However, for the physicists gathered here, the real work had only just begun.
In order to better reveal the physical properties of the pentaquark particle, the LHCb International Cooperation Group assigned tasks to researchers around the world to perform a full spectrum analysis of the newly discovered particle.
After the task was assigned, Professor Lu's research team also devoted themselves to this work.
However, compared to the last "joint examination" with Syracuse University, the time schedule for this mission was not as tight. It could even be said to be quite relaxed.
Later, Lu Zhou asked Yan Xinjue and found out that this was different from the previous thesis. Every "full spectrum analysis" thesis would be co-signed by all the scientific researchers.
If there were too many co-authors, the value of the thesis would be infinitely weakened. Plus, everyone was doing their own thing, so there was no need to compete with anyone. Naturally, no one was in a hurry. According to the workload assigned to each team, one month was more than enough to complete all the work.
Sitting in the hotel conference room, Lu Zhou wrote a draft on an A4 paper while he chatted with Yan Xinjue, who was also working next to him.
"More than a thousand signatures … When I think about the fact that there will be more than a thousand names on my thesis, and that more than half of the names will be in front of mine, my enthusiasm for this job will decrease a lot."
"This is how working for CERN is like this. This is a place where one's success is built on the bones of thousands of people, so I don't recommend you to come here. Although our work is also great, the Nobel Prize can't be given to everyone who witnessed history … "Yan Xinjue yawned and put down his pen. He then stretched and said," Do you want to play billiards tonight? "
Lu Zhou thought for a bit before he shook his head and said, "No thanks, I have something to talk to Professor Grayer about. I have to go to the R2 building's office."
Last time, Professor Grayer promised him that after the experiment was over, he would help Lu Zhou sort out the data from the test channel.
Just now, he received an email from Grayer saying that the data had been sorted out and that Grayer wanted him to bring the USB to the office.
Although it would not take long to copy the data, Lu Zhou wanted to use his leisure time at night to study the data.
After all, he had to work on Professor Lu Zhou's project during the day, so he could only use weekends and nights.
Yan Xinjue saw through Lu Zhou's thoughts and said, "Don't tell me it's about the last time."
Lu Zhou, "You guessed it."
Senior Martial Brother Yan had a defeated expression. He sighed and said, "Okay, I admire your persistence … Although I want to say that you are doing useless work."
Lu Zhou smiled and said, "How would I know if it's useless if I don't try?"
Lu Zhou was like this. He was like this when he was in mathematics, and it was the same when he was in physics.
He was still very interested in the 750 GeV characteristic peak.
Yan Xinjue and Professor Grayer both said that the flat protrusion could not be called a characteristic peak. There was a high probability that it was just a two-photon signal, and there might not even be a collision. Because the energy it carried was too ridiculous. It was even five times the energy of the Higgs particle!
However, Lu Zhou did not think this was the case.
The number 750 GeV might seem a bit "heavy", but it didn't mean that there wasn't a possibility of it being true.
Studying the frontier of any discipline required imagination. In Lu Zhou's opinion, the protrusion of the suspected characteristic peak was enough for him to imagine.
Even for the two experts in quantum chromodynamics, this phenomenon violated "common sense" and had no research value. However, the common sense of physics did not apply to Lu Zhou, who was a mathematician.
How did quantum chromodynamics develop?
Didn't it just subvert "common sense"?
Even if it was wrong, it did not matter. It was an attempt with no cost of failure.
After dinner, Lu Zhou went to the R2 building. Professor Grayer was waiting for him in his office.
"The data you want is in this USB, including the data collected from the CMS detector. I also asked for a copy for you. But to be honest, this data is useless. We only did the 1TeV collision for less than an hour. Other than testing the sensitivity of the detectors, we can't get any useful experimental results. "
Lu Zhou: "Thanks … I'm just trying to satisfy my curiosity. Whether it's useful or not, I still want to try it."
