After arriving at SLAC, Chen Zhou and Friedman had a brief encounter.

This time, only Chen Zhou and Friedman met.

Even Cross was called out by Friedman.

Therefore, the meeting between Chen Zhou and Friedman later triggered countless speculations.

No third person knows what exactly the two said and what decisions they made.

After this meeting, Chen Zhou immediately plunged into intense and exciting work.

Nervousness naturally means that time is tight.

Here at SLAC, Chen Zhou started the retreat mode according to his own research habits.

As for excitement, it means that this unknown road is really going to the end.

No one knows whether what lies ahead is the unsolvable end point or the long-awaited Nobel Prize in Physics.

Friedman also arranged a separate dormitory for Chen Zhou to ensure that Chen Zhou would not be disturbed.

Chen Zhou, who didn't attract much attention when he came to SLAC before, is now the object of SLAC's collective attention.

Therefore, Friedman must ensure Chen Zhou’s research environment.

Friedman also moved Cross's dormitory to the one next to Chen Zhou's to facilitate timely communication between the two.

Cross was quite happy about this at first.

He was very happy to be able to learn Chen Zhou's research methods up close.

But after a long time, he realized that Chen Zhou's method of seclusion and research was not at all what he had imagined for Bai Yueguang.

Cross also finally understood what Chen Zhou said on the way back, "That's a lot, it's all the documents."

In this way, after Chen Zhou started to study in seclusion and liver-explosion, Cross was forced to follow Chen Zhou's footsteps.

Cross himself has never done research like this before, this is simply too desperate!

According to Cross, project research should be a matter of combining work and rest.

Because when you have no inspiration, no matter how hard you work, it's just a waste of time.

But all his inherent thoughts were shattered in front of Chen Zhou.

Cross has never seen Chen Zhou think of a break, nor has he seen him waste time.

What he saw was all serious research, the kind of research that involves thinking.

There is no pretense at all, just sitting around and wasting time.

Cross was very impressed by this.

He guessed that Chen Zhou was probably on the plane, so he finalized the overall research idea.

Otherwise, how could Chen Zhou's research ideas be so smooth, even a little silky...

Chen Zhou didn't care that much, he had his own research rhythm.

This is not the first time he has encountered situations where time is tight and tasks are heavy.

It's just that this time it's a little bit special.

However, no matter what, Chen Zhou will make steady progress towards the established goal.

This is also the most valuable thing about Chen Zhou.

"The starting point for studying hadron spectra using the QCD summation rule is to construct appropriate physical flow operators..."

While Chen Zhou was thinking, he looked at the information in his hand.

This information is the first batch of literature compiled by Cross.

Chen Zhou and Cross's plan is to sort out the research literature on strange quantum number glue balls in each meson state in batches.

Soon, Chen Zhou finished reading the documents in his hands.

After thinking for a moment, he took out a new piece of scratch paper and began to study the 0-state strange quantum number glue ball.

Cross in the next room is also sorting out the second batch of documents.

Originally, Cross planned to work together with Chen Zhou, so that the two of them could communicate directly.

However, after experiencing Chen Zhou's desperate rhythm, it was really difficult for him to adapt.

Especially when he picked up the cup to drink water, Chen Zhou was immersed in research.

When he got up to go to the toilet, Chen Zhou was immersed in research.

When he was hungry and grabbed something to eat, Chen Zhou was still immersed in research.

In other words, no matter what he was doing, no matter when he stopped writing and stood up, Chen Zhou was always immersed in research.

This gave Cross a very sad feeling, feeling that he was holding Chen Zhou back.

Therefore, after much thought, Cross finally decided to work separately from Chen Zhou.

In this way, he is more efficient.

In fact, what Cross didn't know was that because Chen Zhou was not familiar with him before, he completed the entire data processing and completed the paper on the rubber ball experiment by himself.

But now, with him helping him organize documents and materials, Chen Zhou felt happy before it was too late. How could he think that he was holding him back?

After all, Chen Zhou finally has someone he can beat...

Back on the 7th day of SLAC, Chen Zhou analyzed the self-consistency of the glue ball flow operator based on the research on 0-strange quantum number glue balls, and proposed a glue ball flow that can self-consistently describe the physical properties of glue balls.

operator.

And on this basis, we will continue to deepen this research idea.

The self-consistent two-gluon and three-gluon peculiar glue ball flow operators are constructed.

The 0-- and 0-exotic quantum number glueball properties corresponding to the operators are studied in detail, and the corresponding energy ranges are given.

Among them, the mass of the two-gluon 0-- glue ball is about 6.3GeV, and the mass of the three-gluon 0-- and 0-glue balls is about 6.8GeV and 9.8GeV respectively.

Because these glue ball states have unique quantum numbers, they do not mix with ordinary meson states.

Many theoretical studies have shown that their mixing with multiquark states is also minimal.

Therefore, they are the most likely glue balls to be distinguished experimentally so far.

But now, Chen Zhou is not satisfied with this. He does not have time to verify step by step and make adjustments.

He only has this chance.

In other words, Friedman and SLAC only have this one chance.

Therefore, Chen Zhou began to conduct in-depth research based on the feedback from theoretical research on the wrong question collection.

What Chen Zhou needs is a sufficiently complete research theory on glue balls with strange quantum numbers.

This provides absolutely sufficient assurance for the final experimental plan.

As Cross sorted out the second batch of literature, the third batch of literature...

Chen Zhou also began in-depth research again and again, and began to search for the most likely glue ball that could be found and detected in each glue ball state.

"If you construct a model, borrow experimental data from the literature, use mathematical methods as much as possible to rationalize the mathematics, and then study 0-, 1- and 2-odd numbers under appropriate interpolation currents and within the framework of the QCD summation rule

The mass spectrum of the ball…”

Following a new idea, Chen Zhou discovered that there is a stable 0-odd ball with a mass of 4.57±0.13GeV, a stable 2-odd ball with a mass of 6.06±0.13GeV, but no stable 1-odd ball.

.

By analyzing the possible production and decay patterns of these glue balls with peculiar quantum numbers, Chen Zhou used the wrong question set to further carry out paper-based experimental research.

If possible, this could be measured in experiments at SLAC.

Half a month after Chen Zhou arrived at SLAC, Cross took the lead in completing the work of sorting out the literature.

After he finished it, Cross looked at the results of his work, and he couldn't believe it.

If this had been done in the past, he felt that he would never have been able to complete the collection of so many documents so quickly.

Suddenly, a sense of pride arose spontaneously.

Cross even had the urge to report to Friedman.

After packing up the information he had compiled and sending it to Chen Zhou, Cross stood up and stretched his muscles.

Immediately, he came to Chen Zhou.

Not long after knocking on the door, Chen Zhou opened the door.

Seeing that it was Cross, Chen Zhou walked to the desk and said directly: "Professor Cross, I have received the document you sent."

Cross nodded slightly and responded: "Okay."

Then, he just walked into the room minding his own business and saw Chen Zhou sitting at the desk again.

To be honest, Cross really admires Chen Zhou's perseverance.
To be continued...
