Chapter 277: Satisfying Fans’ Requests
Before I knew it, Weibo already had 600,000 fans.
There are still 99+ private messages, most of which are advertisers and strange fans, and some of them directly send him papers. After the lesson learned last time, he will not read any papers or the like.
In the comment area, he also saw that many people were concerned about his progress on the Polignac conjecture. Some people complained that he was too aloof and cold, and at least talked about the recent situation.
Xu Qingzhou said that he was a little wronged. The reason why he did not speak was because he felt that he had no happiness to share with his fans and friends.
But
After thinking about it, he still found the CMS work permit for Song Yao from the photo album.
Editor's message: I'm in France, everything is going well.
[Sodium ion 1323]: I’ll go first, Xu Shen is awesome!
[Xiao Gu who is not closing]: Let me go. Did Xu Shen go to France to participate in the collider experiment?
[roay]: A liberal arts student, although I couldn’t understand it, I was greatly shocked.
Xu Qingzhou was also shocked when he looked at these comments that popped up. It should be around four o'clock in the middle of the night, Xia Kingdom time. Don't you guys sleep?
[Wang Shiba’s Little Moon]: Weibo reveals a strong flavor.
[Hahaha every day]: Xu Shen, aren’t you working on Polignac’s conjecture? Why are you doing physics experiments?
[I love mathematics]: That’s right, we mathematicians can’t be so unprofessional.
[Native Trisolaran]: What you said above is wrong. Xu Shen is good at physics. Isn’t it normal to do physics?
[Boss Yu]: As expected of Peking University, you can participate in the world's top experiments before you are even twenty.
[Xiao Nai]: Don’t be upset upstairs. Everything is related to age. People’s strength should be there.
[Man in Straw Shoes]: Although I admire Xu Shen very much, I have to say that Xu Shen must have gone through the back door this time. This is an experiment in the particle field.
[Waiting for the Wind to Come]: After all, he is the son of Beijing University. If there is a place, of course it will be given to his own people. It would be great to earn more capital for his own students.
Oh~
Quite lively.
After sharing his itinerary with netizens and briefly reading the comments, Xu Qingzhou put away his phone and opened the data analysis report for this period.
In the experiment, batches of accelerated protons collide at nearly the speed of light, creating a shower of particle fragments from an absorption device called a collimator in the collider.
After passing through a series of complex instruments, it is converted into data and appears visually in front of the researchers.
The experimental results are very good. The measured mass, decay width and spin parity of the Higgs particle are all consistent with the predictions of the Standard Model.
This is also one of the significances of the experiment, to verify the correctness of the Standard Model and fill the gaps in its understanding of the source of particle mass.
For researchers like Xu Qingzhou, the happiest thing is probably to explore the basic laws of the material world.
Thinking about it this way, no wonder those who study physics always feel that they have mastered the truth. In fact, they do master the truth.
The data report Xu Qingzhou is opening now comes from the ATLAS experiment, which is also examining the Higgs particle.
With the distribution of constant mass of the filtered two-photon events, it can be seen that the events are clustered near 125GeV, but according to all other known physical processes, only 6340 of them can be contributed here at most. .
Next, are the two-photon invariant mass spectra of the two experiments.
The computer was buzzing, and on the screen, CMSSW was processing data, filtering out the background contribution, leaving only the Higgs particle.
etc.
At this moment, Xu Qingzhou's eyes paused.
From the curve graph, it was found that there was a resonance peak similar to the Higgs particle in the screened out background.
There is a problem.
He threw the previous data into CMSSW again, and then stared at the screen.
Unfortunately, similar resonance peaks did not occur.
Or, an illusion?
But it’s unscientific. I’ve been quitting sex for almost a month, but I still have hallucinations?
Xu Qingzhou had self-doubt and tried again with the data just now.
Or not? Squinting, he rubbed his hands and picked up a piece of manuscript paper.
30 minutes passed.
Xu Qingzhou stopped again. Judging from the current calculations, it is basically certain that the resonance peak just now seems to be generated by the top quark.
According to the theoretical speculation of the Standard Model, there is indeed coupling between particles, and particles are divided into fermions and bosons according to their spins.
Among them, bosons are continuously emitted and absorbed by fermions, causing interactions between fermions, that is, bosons are particles that transmit interactions.
For example, in strong mutual coupling, protons and neutrons couple through strong interactions and maintain the stability of the atomic nucleus by exchanging gluons.
So, this is some kind of coupling between the Higgs particle and the top quark?
Xu Qingzhou couldn't help but feel a little excited. The Higgs particle was discovered too late. After the discovery, the hadron collider was shut down for operation and maintenance.
Therefore, everything about the Higgs particle remains theoretical.
There is much to be done.
Xu Qingzhou took out another piece of paper and listed what needed to be done next.
The data are screened for events that may contain top quarks.
Try to reconstruct the decay process of the top quark.
The workload of the project is huge, but fortunately, this is self-entertainment, and there is no time requirement. You can directly access the CMS experiment database and use the existing experimental data.
Just do it.
Xu Qingzhou turned on the computer and accessed the database, intending to look at previous quark research materials first.
Since he decided to try to verify the existence of the coupling between the Higgs particle and the top quark, Xu Qingzhou has lost his last rest time, but it has allowed him to regain the feeling of his life-threatening experiments.
During this period, he also received a call from Academician Ma of the Quantum Experimental Institute, saying that various tests on the quantum satellite had been completed and the results were very satisfactory.
Now just wait for the final test.
In the busy life, another week has passed and it’s time to take a break.
On the afternoon of the 9th, just after coming out of the laboratory, Zhang Changqing found Xu Qingzhou: "Junior brother, are you looking for a place to relax at night?"
"No, I have to work for Team Leader Shen tomorrow, so I can't drink." Xu Qingzhou said helplessly.
"Team Leader Shen?"
Xu Qingzhou nodded with a smile and said: "The boss, Team Leader Shen, is here and he has to pick him up."
"Academician Chu is here? It's time to pick him up."
Zhang Changqing nodded, with some regret, "Okay, now we are the only ones to have fun."
Xu Qingzhou nodded with a smile and returned to the hotel. Zhang Changqing and Chen Peipei were waiting at the entrance of the laboratory, preparing to go to Geneva together.
Looking at Xu Qingzhou's back, Chen Peipei sighed and said, "Junior brother Xu is so busy. I found that he has been reading information during his break."
"I'm probably preparing my graduation thesis."
"Hiss~ Junior Brother Xu is graduating?!"
"Yes, Peking University is planning to let the juniors graduate early, which is normal. Those undergraduates who have been crushed can finally be liberated. Think about it, if you are a senior and are crushed by your freshman, tsk tsk"
< br>
Chen Peipei hesitated to speak, as if not only the undergraduate, but also she felt like she was being crushed into scum.
Maybe only experts like Senior Brother Zhang will be better.
