Volume 1: Student Life Chapter 428: Lecture, are you going?
October 1st is China's National Day.
Generally speaking, students in China are excitedly spending the first day of the Golden Week holiday.
Unfortunately, Chen Zhou is now at MIT.
Today is just an ordinary Saturday.
Just like before, Chen Zhou and Yang Yiyi started their new day with a morning run.
In the dormitory, Chen Zhou habitually glanced at the desk next to him.
Yang Yiyi was not there.
Even though today is Saturday.
But Yang Yiyi was still called away by her mentor who had just returned from receiving the award and giving a speech.
Chen Zhou estimated that next, Yang Yiyi would most likely follow Professor Rainer Weiss to LIGO.
During the time when Rainer Weiss was away, Yang Yiyi can be said to have worked very hard.
Not only did he complete the task assigned by Rainer Weiss before leaving excellently.
I also added a lot of tasks to myself.
Retracting his gaze, Chen Zhou turned his thoughts to the topic of rubber balls.
"Last night, I fell asleep with mathematics, so this morning it's physics..."
Thinking of this, Chen Zhou took out the information related to the topic .
Now Chen Zhou has changed his learning mode into a rotation mode.
It's a half-day physics and half-day mathematics method.
The cross-disciplinary study of these interrelated subjects can also help regulate thinking.
However, the time to switch to rotation mode was much earlier than originally planned.
Chen Zhou originally planned to sort out the glueball theory of conventional quantum numbers and the glueball theory of those strange quantum numbers, and then adjust the plan to a rotation mode.
But now, Chen Zhou has only studied the glueball theory of conventional quantum numbers.
We are currently entering the stage of summary and feedback.
However, Chen Zhou has not yet started research on the glueball theory of strange quantum numbers.
The reason why Chen Zhou changed, or accelerated the original plan, was that he felt that there was still a long time before the next experiment on the rubber ball.
Instead of spending most of the time on the experimental topic of glue balls.
It would be better to balance it out from the beginning.
There is enough time for the experiment topic on rubber balls.
And no one can say for sure how long it will take.
And by rotating between studying physics and mathematics, maybe I'll get some inspiration because of the buff of the implications of the subjects?
So Chen Zhou made such a change in advance.
On the draft paper were the contents that Chen Zhou had recorded yesterday afternoon when he was studying the theoretical model of the rubber ball.
After taking a look at these contents, Chen Zhou's thoughts immediately connected to yesterday afternoon.
At the same time, Chen Zhou opened the collection of wrong questions.
Since the plan has changed, there is no need to catch up on time.
Chen Zhou planned to use the collection of wrong questions together.
Through the feedback from the wrong question collection, we can correct any errors that may exist in the theoretical model.
The main mechanisms for the generation of colloid balls are:
【（Ⅰ）J/Ψ or Υ radiation decay;】
【(II) Central production of mesons;】
【（Ⅲ） Proton-antiproton annihilation process;】
【(IV) Decay process of excited state to ground state of type Υ particles. 】
The main decay modes of glueballs are:
【（Ⅰ）G→gg→q▔qq'▔q'→MM′,】
【(Ⅱ)G→gg→ggg→η(η′)η(η'),】
【(Ⅲ)G→gg→q▔qq▔qq'▔q'→MM′,】
[Wherein, G represents glueball, and M (M′) represents meson. ]
Chen Zhou looked at the "mechanism of glue ball production" and "main decay mode of glue balls" that he had written on the draft paper at the beginning.
The research on the theoretical model of rubber balls during this period kept coming to my mind.
It can be said that almost all theoretical model calculations on the mass of colloid balls are corresponding studies centered around "mechanism" and "decay mode".
However, even if we know the "mechanism" and "decay mode".
Even the theoretical model calculations derived from this have reasonably predicted the mass range of the colloid balls.
However, in experiments, no definite conclusion has been reached even for the lightest scalar glueball state.
Not to mention other jellyball states with more complex internal structures and higher masses.
There is no least amount of information on experiments, only less.
Although Chen Zhouyuan has not yet reached the stage of moving from theory to experiment.
However, the results of so many years of experiments are here.
For decades, this piece of the Standard Model puzzle remained elusive.
"Starting from the 'mechanism', we built a theoretical model based on the 'decay mode' and performed theoretical calculations of the mass of the glueball."
"There are no major problems with the entire process..."
While flipping through the collection of wrong questions, Chen Zhou was sorting out the theoretical models he had studied during this period.
The content in the collection of wrong questions is not small.
But there is no point that directly overturns a theoretical model.
Basically, they are all supplements and improvements to the original models.
As for this point about the collection of wrong questions, Chen Zhou didn't know what to say.
It would be fine if he could organize these contents and write a complete paper.
Moreover, the value of this paper is not low.
If you are submitting to a journal, there is no problem in submitting to an SCI journal in the first or second zone.
After all, this is a perfection and improvement of all theoretical models for studying conventional quantum number glueballs.
Who knows, some talented physicist might get inspiration from it.
So as to truly find the rubber ball.
However, Chen Zhou felt that it was unnecessary.
This is not the final result, why send it out?
It doesn't mean much.
If I really want to publish a paper on the topic of rubber balls.
That must be when the gumball was found.
Only then would Chen Zhou write all his theoretical and experimental research into a complete paper and submit it to "Nature" or "Science".
That is, "Nature" and "Science", two top journals that countless scientists dream of.
Of course, this is all based on the fact that Chen Zhou and his research team were able to discover the glue balls.
Moreover, Chen Zhou's contribution to this research group needs to be large enough.
Chen Zhou couldn't say for sure whether he could find the legendary rubber ball.
However, compared to Friedman's arrangements for other researchers at the seminar.
Chen Zhou felt that the possibility of his unilateral victory should be even higher.
[On the particle table PDG, the number of confirmed scalar mesons is obviously more than the number expected by the quark model, and their masses are all lower than 2GeV, which means that the possibility of the existence of 0++ glueballs is very high! ]
[However, since mixing occurs between quark states and glueball states, scalar glueballs are more likely to appear in the form of a mixture with other hadron states, which makes it difficult to clearly identify them experimentally...]
In one morning, Chen Zhou completed the sorting out of the theoretical model knowledge of conventional quantum number glueball as expected.
Yang Yiyi hasn't come back yet and has been in Professor Rainer Weiss's office all morning.
Chen Zhou stretched and then stood up.
He planned to go find Yang Yiyi, and it was time for dinner.
However, Chen Zhou didn't have time to walk out of the dormitory.
His cell phone started ringing.
The person who called Chen Zhou was Liu Maosheng.
Chen Zhou pressed the answer button and asked politely, "Brother Liu, what's the matter?"
Liu Maosheng said excitedly: "There is a lecture at MIT this afternoon. Do you want to go?"
