Chapter 170: Perfect theory

The data is at hand, and how to deal with it becomes a problem.
Starting from the theory of quantum chromodynamics, there is no theoretical support.
However, from a statistical point of view, the sample size is too small to draw any useful conclusions.
After analyzing five full G data for five nights, Lu Zhou finally came to a conclusion.
In order to confirm whether this anomalous bump is a characteristic peak, after all, you still have to run a few laps on the hadron collider. With the current amount of data, the accumulated examples are not even 3sigma's confidence, not even a "sign" in physics, let alone "discover".
After building the car behind closed doors for five nights, Lu Zhou found Academician Lu with the research results and data from these five days.
It is impossible for him to persuade CERN alone. After all, his identity is only an intern and the weight is still too light.
After clarifying his viewpoint to Academician Lu, Lu Zhou thought that the old gentleman would not agree with his opinion, but at least he would be emotional about the discovery, but did not expect to get a negative answer.
"The Hadron Collider cannot start because of a sudden whimsy. You have to look for 750GeV particles. The collision energy must be at least 2TeV or even 2TeV. This cost is not a small number, let alone LHC. The schedule is very full. CERN still has endless experiments to do. Everyone wants to verify that his theory is correct, but the funding is limited. "
Lu Zhou did not give up on this, trying to persuade: "Professor, since the 'post-standard model era', we have not discovered any new particles. Don't you think this might be an opportunity?"
Yes, both the four-quark state and the five-quark state particles that have been found are particles that have been observed before, except that the confidence is lower than 5 sigma. They are called "signs" in academia and cannot be identified as "Find".
If the signal appearing at 750 GeV is confirmed to have a new particle, what the land boat means for physics is unclear, because he does not know what the particle will be there.
But for him personally, he can be sure that once this discovery is determined to be true, at least it will also be a Nobel Prize.
"To be honest, I'm not very optimistic," Academician Lu shook his head when he heard what Lu Zhou said, "750GeV is too heavy. From the perspective of quantum chromodynamics, this is out of theoretical foundation."
Lu Zhou emphasized: "But we have observed this signal on the CMS detector! Do you think this is just a coincidence?"
"Yes, you are right, he is not necessarily a coincidence," Academician Lu nodded and pointed to the data on the paper. "But have you ever thought about it, it may be just a two-photon generated when the gluon aggregates?" signal?"
Lu Zhou nodded: "You are right, this possibility does exist, but it is for this reason that I need to use experiments to prove that my guess is correct!"
Looking at his students becoming more and more excited, Academician Lu smiled, paused for a moment, and sighed, "I understand the excitement in your heart, but similar things have not happened before. And I personally As far as I am concerned, I would like to help you to test this result, but unfortunately, we are not a member of CERN, but a cooperating country. Neither I nor Mizuki University's Gao, here is not very talkative. Shanghai BES, this experiment cannot be done. "
Lu Zhou fell into silence.
As the old man said, the Hadron Collider belongs to someone else, and it must be a priority to do its own research. Unless you can come up with solid evidence and don't talk directly to the person in charge of CERN, at least get them interested in your theory.
However, this has fallen into an endless loop.
If experiments are not performed on this energy region, there will be no evidence at all. Unless you wait for others to do collision experiments above 1TeV, and then look for these scraps from other people's data
But when does this have to wait?
And even if you discover these things at that time, most of them have nothing to do with yourself.
After all, he couldn't stay in CERN and stared at other people's experiments. He had to finish his studies and go to Princeton to read a Ph.D.
When he arrived in his room, Lu Zhou wandered on the bed and looked up at the paper in his hands and was in a daze.
Suddenly he coughed softly and asked in a low voice.
"System, are there any particles in 750GeV?"
The system did not respond.
Is it because the physical level is not enough?
Or is it because this kind of question is also a directional question? According to his previous experience, all questions related to directionality are not within the system's answering interval.
MMP, more and more that this point is useless.
Taking a deep breath, Lu Zhou sat up from the bed.
It is too early to give up, not to mention that he is not a person who will give up easily.
Actually, there are opportunities.
CERN couldn't launch a hadron collider for one of his interns because he didn't have enough weight.
If that's the case, find someone who has enough weight to convince the person in charge of CERN for him!
Recently, so many big cattle in the theoretical physics community have gathered here, and there are still many people with this weight.
Not surprisingly, these people will stay until the end of the month, after CERN convenes the European Nuclear Research Conference to report the results of the five-quark state particle research, then gradually withdraw from here.
Now Lu Zhou has only one thing to do, and that is to perfect his theory before the end of the month.
Perfecting the theory may seem simple to say, but it is not so easy to do in practice.
If this physics problem is to be transformed into a mathematical problem, one of the key points is that he must use mathematical methods to prove that when the sample is sufficient, the bumps that appear in the 750GeV energy range will definitely form a characteristic peak.
It sounds like this is just a statistical problem, but in the absence of samples, it is almost impossible to simply use statistical tools to solve this problem.
He needs more evidence.
Then analyze the new conclusions from this evidence.
"This is the experimental data collected on the CMS detector when the LHC searched for the Higgs particles from 12 to 13 years, but you should know that the Higgs particles are only 125GeV, and we did not use collision energy when looking for this It's so big. "
In the office, Professor Greer threw the USB flash drive into Lu Zhou's hand.
After taking the USB drive, Lu Zhou sincerely said, "It's okay, I'm very grateful!"
After thinking about it, it seems that he can only ask for this one.
Although the two haven't known each other for a long time, the Professor Greer and him have unexpectedly gotten together in character. Although not optimistic about the content of Lu Zhou's research, the professor did not dissuade him, but helped him collect a lot of valuable data.
Although these documents are not confidential, they are not completely open to the public. If there is no one in CERN who knows it, it is really not easy to get these data as an intern.
Professor Greer smiled and said, "You're welcome, it's a trivial matter. Did your research progress?"
Lu Zhou nodded and said, "There is already a bit."
Professor Greer reminded: "If you want to use the hadron collider, my suggestion is to find someone with sufficient weight in theoretical physics to cooperate instead of building a car behind closed doors. After all, no matter how much your theory does In the end, it still has to be supported by LHC data. "
Lu Zhou: "That's what I planned, but before that, I want to make my theory a bit more reliable."
Professor Greer asked: "Are there any suitable goals?"
Lu Zhou shook his head: "Not yet"
He is ready to wait for the theoretical preparation to be a little more perfect, then take the papers and try them one by one using the method of wide-spreading the net ~ EbookFREE.me ~ For example, squatting on a big boss ’s lecture, wait until the lecture is over Going up with the paper.
If that doesn't work, he can't help it.
Professor Greer thought about it and asked casually: "Need I recommend you one?"
Lu Zhou froze slightly and immediately said, "Of course I need it! Do you have any good suggestions?"
Seeing Lu Zhou's eager look, Professor Greer smiled and said, "Frank Wilzek, the 2004 Nobel Prize winner in physics, is probably the best person to talk to. I know everyone. If you It might be hopeful to convince him. "
