The flight from Yenching Capital International Airport to San Francisco takes about 12 hours.

In the past 12 hours, except for the bumpy state when the plane took off at the beginning, Chen Zhou put away his things according to the requirements of the flight attendant.

The rest of the time, his mind was all about the rubber ball experiment.

Friedman's idea, to be precise, is an all-or-nothing idea.

The landing point of this idea is the oddball, that is, the strange quantum number rubber ball.

Friedman hopes that Chen Zhou can further explore the feasibility of the strange quantum number rubber ball from this direction from the theoretical research.

The final feedback was given to this last rubber ball experiment.

Originally, Chen Zhou's paper had two major contents: a conventional quantum number rubber ball and a peculiar quantum number rubber ball.

Before Friedman encounters the current predicament of SLAC, he also intends to fully embark on the two experimental contents of the conventional quantum number rubber ball and the strange quantum number rubber ball.

However, in the current situation, they can only choose one of the most likely directions and go all-in!

In this case, Friedman chose the most adventurous direction of the peculiar quantum number rubber ball.

This is also the reason why Chen Zhou was silent for so long after hearing Friedman's idea.

Of course, this was Friedman's choice after some deliberation.

The experiment of conventional quantum number rubber balls is too common and too ordinary.

It is already difficult to accomplish such a big leap forward in the innovation and breakthrough of theoretical research content.

In the experiment, the rubber ball has never been found.

Therefore, Friedman intends to abandon this conventional direction and abandon the study of conventional quantum number rubber balls.

Admittedly, Friedman had an element of gambling.

But it has reached the current situation, rather than leaving with nothing, it is better to gamble on it.

Moreover, judging from a variety of research literature, there are many reasons to show that the research of peculiar quantum number rubber balls may be a key to open the "door to the world of rubber balls"!

At the same time, in Friedman's view, most of what is lacking in the study of peculiar quantum number rubber balls is theoretical, how to study the quality and generation of peculiar quantum number rubber balls, and the decay properties clearly.

Then, for the final experimental plan, the research direction is indicated and the search scope is narrowed.

Therefore, the direction of the peculiar quantum number rubber ball is likely to be a new winning point.

And the person who can solve this problem, Friedman thinks of Chen Zhou.

Whether it is this amazing paper handed over to him by Chen Zhou, or the paper that Chen Zhou previously published as the first author.

All of them convinced Friedman that Chen Zhou could solve the theoretical problem of a strange quantum number rubber ball.

Then the rest is whether Chen Zhou is willing or not, and whether he can go all out.

This is also the phone call from Friedman before Chen Zhou boarded the plane.

To be honest, Chen Zhou really didn't expect that Friedman would make such a choice.

In his opinion, Friedman is more likely to choose a conventional quantum number rubber ball as a final experimental plan.

Because in Chen Zhou's cognition, Professor Friedman is the kind of physicist of the older generation who has an old-fashioned appearance and a very "old" personality.

They have that old-fashioned rigor.

But now it seems that perhaps Professor Friedman, in addition to his rigor, is looking for the only beacon in the darkness.

And this is also what Chen Zhou admires.

It is also the reason why he will say that since Friedman is not afraid, he will naturally go all out.

As for the specific research in the direction of peculiar quantum number rubber balls, Chen Zhou is not too sure.

However, his intuition told him that the true body of the new hadron state of the rubber ball was most likely here.

"He seems to be a young scholar?" the flight attendants on the plane gathered together, and the object of discussion was none other than Chen Zhou.

Because Chen Zhou is so different from ordinary people who take planes.

In front of Chen Zhou, there was a bit too much scratch paper piled up.

Moreover, this is the first person these flight attendants have ever seen to finish writing the refill of the pen and fountain they carried with them on the plane.

Hearing his colleague's words, the beautiful flight attendant who had had a brief conversation with Chen Zhou glanced at Chen Zhou, and then said softly: "If he is a scholar, he must have made some surprising discoveries, which is why he is so obsessed with the work in front of him." ”

My colleague asked strangely, "How do you know?"

The beautiful flight attendant replied with a smile, "Because of his smile, it's so memorable." People with that kind of warm smile will be able to create amazing things in their work!"

Chen Zhou, who was frowning and thinking, obviously wouldn't have thought that his unintentional smile would actually bring people such a special feeling.

"The rubber sphere itself is a quantum chromodynamics (QCD) language, a special class of microscopic particles, composed entirely of gluons......"

"Because most of the rubber balls have similar quantum numbers to ordinary mesons, the researchers triggered them from the QCD summation rule......"

"Although the peculiar quantum number rubber ball has a completely different quantum number from the ordinary meson, the general method of its theoretical research is still to start from the QCD summation rule, comprehensively consider the perturbation and non-perturbation contributions, and systematically study the properties of the peculiar quantum number rubber ball......"

After Chen Zhou straightened out his research ideas, the speed of writing increased again.

And the scratch paper in front of me is also constantly consuming at a very fast pace.

In fact, the search for rubber balls is a direct test of strong interactions.

It is of great significance for the study of gluon fields and the understanding of color confinement.

The perturbation and non-perturbation that Chen Zhou thinks about are because of the strong interaction, which will become stronger with the decrease of the energy scale, resulting in the failure of the perturbation theory in the low energy region.

Therefore, it is necessary to establish a non-perturbation model to study the properties of the rubber balls.

The QCD summation rule adopted by Chen Zhou is an extremely effective non-perturbation theory.

It can equate the non-perturbation effect in quantum chromodynamics with vacuum condensation, and study the properties of rubber balls through analytical methods.

As for the reason why it is very difficult to find and identify the rubber ball, it is because the rubber ball and the conventional meson composed of quarks have the same quantum number.

In this case, the observed meson spectrum may be the result of the mixing of the rubber ball with the ordinary meson.

In general, in order to determine the rubber ball, theoretically and experimentally, it is necessary to carry out a systematic and precise study.

On the one hand, additional resonance states are found that exceed the expectations of the quark model.

On the other hand, it is necessary to measure the properties of each resonance state, such as self-selected symmetry, mass, width, and decay rate, and find anomalous properties that are difficult to explain with a simple quark model.

Here, the peculiar quantum number rubber ball has great research value.

There are some quantum numbers that cannot be explained by the traditional quark theory, that is, exotic quantum numbers.

Rubber balls can have exotic quantum numbers.

This kind of rubber ball with a peculiar quantum number will not mix with ordinary mesons, which is conducive to experimental observation.

Chen Zhou estimated that this was also the most important reason why Friedman finally chose this direction.

The plane was steadily following the voyage to San Francisco, flying.

Outside the window, it was completely dark.

This flight is equivalent to moving from "day" to "night" in the direction of the sun.

So, most of the time, the plane will fly in the night sky.

On the plane, many people fell asleep.

Only the handsome young man of Huaguo was still turning on the light, and he was concentrating on the scratch paper, seeking the desperate answer.

San Francisco International Airport, also known as San Francisco International Airport, is located on Airport Boulevard in San Mateo County, California.

Primarily serving San Francisco and surrounding cities, it is the second-largest airport in California.

Chen Zhou's direct flight from United Airlines landed at San Francisco International Airport at this moment.

Chen Zhou has also packed his luggage and belongings, the most important thing is the scratch paper he harvested along the way.

This stack of scratch paper was sorted and sorted out by Chen Zhou, and then stuffed into the second layer of the backpack along with the set of mistakes.

After the plane was parked smoothly outside the terminal, Chen Zhou got up and lined up to get off the plane.

When passing by the hatch, Chen Zhou ran into the beautiful flight attendant again.

Chen Zhou smiled politely at the other party: "Good morning, I hope today is still a good day." ”

"Good morning, I believe today will be a good day!" After the flight attendant finished speaking, she glanced at Chen Zhou and asked curiously, "Are you a graduate student at Stanford University......?"

When Chen Zhou heard this, he explained: "No, I am a researcher in the SLAC laboratory, and I am thinking about our topic all the way. ”

"That's right......" the flight attendant nodded lightly when she heard this, "I'm sure you'll get the answer soon, come on!"

Chen Zhou smiled softly: "Thank you." ”

After Chen Zhou stepped off the plane, the flight attendant heard someone on the plane talking about what Chen Zhou had just said.

"SLAC labs? Isn't that the National Accelerator Laboratory?"

"Yes, on the plane, I noticed the man, who seemed to be completely immersed in his own world. As I passed by him, I had a sneaky look twice......"

"What is he working on? What field of high-energy physics?"

"Strange Quantum Number Rubber Ball!"

"The Nobel Prize topic?"

"Yes......"

It wasn't just the flight attendant who was surprised to hear the conversation, but even everyone else was looking at the two people who were talking.

Chen Zhou's actions on the plane actually attracted a lot of attention.

But they didn't know exactly what Chen Zhou was doing.

Now after these two people say this, they really can't believe that the young and handsome person who looks like a Chinese student is actually studying a Nobel Prize-level topic?

Moreover, the SLAC National Laboratory in the San Francisco Bay Area, this is not something that ordinary people can enter, right?

Just by the name, this is a national laboratory!

Is there a national laboratory in any country where ordinary people can enter and become researchers?

Just when people were speculating about Chen Zhou's identity, a person next to the beautiful stewardess who greeted Chen Zhou suddenly said: "I remember who he is, I said how can I see it somewhere......"

The beautiful stewardess wondered, "Have you seen him?"

The man replied: "I haven't seen the real person, I've seen it in the newspaper......"

"Newspapers?"

"The news of last year's Cole Number Theory Prize, the Chinese student who won the award, is him!"

As soon as this remark came out, it immediately caused a sensation.

There are also other people who remembered the news of the Cole Number Theory Award, and immediately began to take a seat and confirmed Chen Zhou's identity.

Whether it is Chen Zhou's young face or his identity as a winner of the Kohl Number Theory Prize, he studies the topic of physics.

Again, this made them feel incredible.

The only different voice is probably that there is a young flight attendant who actually said in a way: "He's so handsome~"

Chen Zhou, who had already walked into the terminal, didn't know what was happening behind him.

At this moment, he is looking for Professor Cross who came to pick him up.

After a while, he saw Cross holding a pick-up sign.

Cross also saw Chen Zhou, and hurriedly held the card in one hand, and waved it vigorously at Chen Zhou with the other hand.

Seeing this, Chen Zhou waved at him, indicating that he had seen it.

After the two converged, they went straight to the parking lot to pick up the car.

In the car, Cross said, "Do you want to sleep for a while, I guess you haven't had a good rest on the road, right?"

Cross had heard a lot about this kind of research madness.

Friedman also specially explained to him that after receiving Chen Zhou, it was best to arrange for Chen Zhou to rest in the car.

Otherwise, he was worried that Chen Zhou had not rested on the plane, and when he arrived at SLAC, he immediately devoted himself to research work, and his body would not be able to stand it.

"I'm fine. Chen Zhou shook his head, and his thoughts once again returned to the strange quantum number rubber ball.

Cross glanced at Chen Zhou: "Okay, if you're sleepy, just sleep for a while, I'll try to drive it as smoothly as possible." ”

Chen Zhou nodded lightly: "Thank you." ”

Cross immediately waved his hand: "We should say thank you to you......"

Chen Zhou turned his head to look at Cross and didn't say anything.

After a pause, Cross continued, "Just like last time, Professor Friedman sent me to you, for the sake of this desperate direction, this time, you don't want to leave me out the whole time......"

Chen Zhou raised his head slightly and said with a smile: "Professor Cross, don't worry, even if you don't say it this time, I need your help." Although the systematic study of rubber balls, I have done it in my last paper. ”

"But now it's a more in-depth study of the peculiar quantum number rubber ball, and I still need a lot of literature to analyze, so I definitely can't do it alone. ”

When Cross heard this, he immediately said: "If you want me to do something, you can say! If you still need manpower, you also say, I will find another person!"

For Chen Zhou's ability, Cross already has a clear understanding.

If time permits, Cross feels that Chen Zhou is absolutely able to easily complete the rubber ball experiment through experimental verification again and again.

Instead of choosing an all-or-nothing direction for the final experimental plan of SLAC, as is the case now.

In terms of time, squeeze yourself to the extreme.

And even if Chen Zhou rejected Friedman, Cross felt that Friedman would not, and there was no reason to blame Chen Zhou.

They are the same, there is no reason to blame Chen Zhou.

It's just that when Chen Zhou chose to stand with them and go all out.

Cross's heart was very touched.

Although he didn't understand why Chen Zhou made such a choice.

Chen Zhou thought for a while and said, "Professor Cross, I ask you to collect and sort out all the literature related to Oddball's research." ”

Hearing Chen Zhou's words, Cross subconsciously asked, "Is that all?"

Chen Zhou said with a smile: "This is a lot, it is all the literature!"

Cross was stunned for a moment, but quickly said, "Wrap it up on me!"
