Chapter 480
Chapter 480 Desperate Direction
The flight from Yanjing Capital International Airport to San Francisco takes about 12 hours.
During these 12 hours, except for the turbulence when the plane took off, Chen Zhou put away his things according to the flight attendant's request.
For the rest of the time, he was preoccupied with the glueball experiment.
To be precise, it was Friedman's desperate idea.
The starting point of this idea is the oddball, that is, the strange quantum number glue ball.
Friedman hoped that Chen Zhou could dig out the feasibility of strange quantum number glue balls from this direction and further in-depth theoretical research.
The final feedback is on this last glue ball experiment.
Originally, Chen Zhou's thesis had two parts: conventional quantum number glue balls and strange quantum number glue balls.
Before Friedman encountered the current predicament of SLAC, he also planned to fully embark on the two experimental contents of the conventional quantum number glue ball and the strange quantum number glue ball.
However, in the current situation, they can only choose the most likely direction, and then put all their eggs in one basket!
In this case, Friedman chose the most adventurous direction of strange quantum number glue balls.
This is why Chen Zhou was silent for so long after hearing Friedman's idea.
Of course, this is Friedman's choice after some careful consideration.
The experiment of conventional quantum number glue ball is really too common and too ordinary.
Innovation and breakthroughs in theoretical research content have been difficult to complete that kind of big leap.
In experiments, no glue balls have been found.
Therefore, Friedman intends to abandon this conventional direction and abandon the research of conventional quantum number glue balls.
To be sure, Friedman was taking a gamble.
But they have already reached the current situation, and instead of leaving with nothing, it is better to gamble with all their eggs in one basket.
Moreover, judging from a variety of research literature, there are many reasons to show that the study of strange quantum number glue balls may be a key to open the "gateway to the world of glue balls"!
At the same time, in Friedman's view, most of what is lacking in the study of strange quantum number gumballs is theory, how to study the mass, generation and decay properties of strange quantum number gumballs clearly.
Then for the final experimental plan, indicate the research direction and narrow the search field.
Therefore, the direction of the strange quantum number glue ball is likely to be a new winning point.
As for the person who can solve this problem, Friedman thinks of Chen Zhou.
Whether it is this amazing paper that Chen Zhou handed over to him, or the paper that Chen Zhou published as the first author before.
All convinced Friedman that Chen Zhou could solve the theoretical problem of the strange quantum number glue ball.
Then the rest is up to Chen Zhou whether he is willing to go all out or not.
This also led to the phone call from Friedman before Chen Zhou boarded the plane.
To be honest, Chen Zhou never thought that Friedman would make such a choice.
In his opinion, Friedman is more likely to choose the conventional quantum number glue ball as the final experimental plan.
Because in Chen Zhou's cognition, Professor Friedman is a physicist of the older generation with a rigid appearance and a very "old" personality.
They have that stuffy rigor.
But now it seems that apart from being rigorous, what Professor Friedman hopes to find is the only lighthouse in the darkness.
And this is what Chen Zhou admired.
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 the strange quantum number glue ball, Chen Zhou is not too sure.
However, his intuition told him that the real body of the new hadron state, the glueball, is most likely to be here.
"He seems to be a young scholar?" The flight attendants on the plane gathered together, and the object of discussion was Chen Zhou.
Because Chen Zhou is really different from the general people who take the plane.
In front of Chen Zhou, there were too many draft papers piled up.
Moreover, this is the first time these flight attendants have seen, on the plane, give the fountain pen refill that they carry with them to the person who finished writing.
Hearing what the colleague said, the beautiful flight attendant who had a brief conversation with Chen Zhou glanced at Chen Zhou, and then said softly: "If he is a scholar, he must have discovered something surprising. , That's why I'm so obsessed with the work in front of me."
The colleague asked strangely: "How do you know?"
The beautiful flight attendant replied with a smile: "Because his smile is so unforgettable. People with that kind of warm smile will definitely be able to create amazing things at work!"
Chen Zhou, who was frowning and thinking, obviously didn't expect that his unintentional smile would bring such a special feeling to people.
"Glueball itself is the language of quantum chromodynamics (QCD), a special kind of microscopic particle, composed entirely of gluons..."
"Also because the quantum numbers of most glueballs are similar to ordinary mesons, the researchers are triggered from the QCD summation rule..."
"Although the strange quantum number jellyball has a quantum number completely different from that of ordinary mesons, the general method of its theoretical research is still based on the QCD summation rule, fully considering the perturbation and non-perturbation contributions, systematic research The properties of strange quantum number gumballs..."
After Chen Zhou straightened out his research ideas, the speed of writing increased again.
And the draft paper in front of him was also being consumed at an extremely fast pace.
In fact, looking for glueballs is a direct test of strong interactions.
It is of great significance for studying gluon field and understanding color confinement.
The perturbation and non-perturbation Chen Zhou thinks about is because of the strong interaction, which will become stronger as the energy scale decreases, which will cause the perturbation theory in the low-energy region to fail.
Therefore, it is necessary to establish a non-perturbative model to study the properties of glue balls.
The QCD summation rule adopted by Chen Zhou is an extremely effective non-perturbative theory.
It can equate the non-perturbation effect in quantum chromodynamics with vacuum condensation, and study the properties of glue balls through analytical methods.
As for why it is so difficult to find and identify glueballs, it is because glueballs and regular mesons composed of quarks have the same quantum number.
In this case, the meson spectrum observed in the experiment may be the result of the mixing of glue balls and ordinary mesons.
In general, in order to identify glueballs, systematic and precise studies are required, both theoretically and experimentally.
On the one hand, additional resonance states are found beyond those expected from the quark model.
On the other hand, it is necessary to measure properties such as self-selected parity, mass, width, and decay rate of each resonance state, and find abnormal properties that are difficult to explain with simple quark models.
Here, the strange quantum number glue ball has great research value.
There are some quantum numbers that cannot be explained by the traditional quark theory, which are strange quantum numbers.
And glueballs can just happen to have exotic quantum numbers.
This kind of glueball with strange quantum numbers will not mix with ordinary mesons, which is beneficial to experimental observation.
Chen Zhou estimated that this was also the most important reason why Friedman finally chose this direction.
The plane was flying steadily along its way to San Francisco.
It was completely dark outside the window.
This flight is equivalent to going from "day" to "night" from the direction against the sun.
So, most of the time, this plane will fly in the night sky.
On the plane, many people fell asleep.
Only that handsome young man from Huaguo, with the light on, was concentrating on the draft paper, searching for the desperate answer.
San Francisco International Airport, also known as San Francisco International Airport, is located on Airport Drive in San Mateo County, California, United States.
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, the most important thing is the draft paper he harvested along the way.
This pile of draft paper was sorted and sorted by Chen Zhou, and then stuffed into the second layer of the backpack together with the set of wrong questions.
After the plane stopped smoothly outside the terminal, Chen Zhou stood up and queued up to get off the plane.
When passing by the cabin door, Chen Zhou ran into that beautiful stewardess 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 stewardess finished speaking, she took another look at Chen Zhou and asked curiously, "Are you a graduate student at Stanford University? I see that you have been writing what..."
Chen Zhou heard the words and explained: "No, I am a researcher in the SLAC laboratory. I have been thinking about our subjects along the way."
"That's it..." The stewardess nodded slightly after hearing the words, "I believe you will get the answer soon, come on!"
Chen Zhou smiled softly: "Thank you."
After Chen Zhou got off the plane, the stewardess heard someone on the plane talking about what Chen Zhou said just now.
"SLAC lab? Isn't that the National Accelerator Laboratory?"
"Yes, on the plane, I noticed the man just now. He seemed to be completely immersed in his own world. When passing by him, I once glanced quietly..."
"What is he working on? What field of high-energy physics?"
"Strange Quantum Number Glue Ball!"
"The Nobel Prize project?"
"Yes……"
Not only was the stewardess surprised by the conversation she heard, but everyone else was also looking at the two talking.
Chen Zhou's actions on the plane actually attracted the attention of many people.
But they didn't know what Chen Zhou was doing.
Now that these two people have said this, they really can't believe that the young and handsome Huaguo student is actually researching a Nobel Prize-level subject?
Moreover, the SLAC National Laboratory in the San Francisco Bay Area is not accessible to ordinary people, right?
You can tell just by the name, this is a national laboratory!
In which country's national laboratory can ordinary people enter and become researchers?
Just when people were guessing about Chen Zhou's identity, a person next to the beautiful stewardess who greeted Chen Zhou suddenly said, "I remembered who he is, and I said he looked like somewhere..."
The beautiful stewardess asked suspiciously, "Have you seen him?"
The man replied: "The real person has never seen it, but saw it in the newspaper..."
"newspaper?"
"The news about the Cole Number Theory Award last year, the Chinese student who won the award is him!"
As soon as this remark came out, it immediately caused another commotion.
Others also remembered the news about the Cole Prize in Number Theory, and immediately started checking in, confirming Chen Zhou's identity.
Whether it's Chen Zhou's youthful face, or his identity as the winner of the Cole Number Theory Prize, he studies physics topics.
This made them feel incredible again.
The only different voice was probably that a young stewardess said in a nympho: "He's so handsome~"
Chen Zhou, who had already entered the terminal, didn't know what happened 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 reception sign.
Cross also saw Chen Zhou, and quickly held the card with one hand, while waving the other hand vigorously at Chen Zhou.
Seeing this, Chen Zhou waved his hand at him to show that he saw it.
After the two met, they went straight to the parking lot to pick up the car.
In the car, Cross said: "Would you like to sleep for a while, I guess you haven't had a good rest on the way, have you?"
Cross has heard a lot about this kind of research madman.
Friedman also specifically explained to him that after receiving Chen Zhou, it is best to arrange for Chen Zhou to rest in the car.
Otherwise, he was worried that Chen Zhou would not take a break on the plane, and he would immediately devote himself to research work when he arrived at SLAC, and his body would not be able to bear it.
"I'm fine." Chen Zhou shook his head, and his thoughts returned to the strange quantum number glue ball again.
Cross glanced at Chen Zhou: "Well, if you are sleepy, just sleep for a while, I will try to drive as smoothly as possible."
Chen Zhou nodded lightly: "Thank you."
Cross waved his hand immediately: "We should say thank you to you..."
Chen Zhou turned his head and glanced at Cross, but didn't say much.
After a pause, Cross said again: "Same as last time, Professor Friedman assigned me to you, for this desperate direction, this time, don't leave me alone..."
Chen Zhou raised his head slightly, and said with a smile: "Professor Cross, don't worry, even if you don't tell me this time, I still need your help. Although I have already completed the systematic research on glue balls in the last thesis. "
"But now it is a more in-depth study of the strange quantum number glue ball, and I still need a lot of literature to analyze, so it is definitely not enough for me alone."
When Cross heard the words, he immediately said, "If you want me to do something, just say it! If you still need manpower, you say it too, and I'll find someone else!"
Cross already had a clear understanding of Chen Zhou's abilities.
If time permits, Cross feels that Chen Zhou will definitely be able to easily pass the experimental verification again and again, and perfectly complete the rubber ball experiment subject.
Instead of choosing a desperate direction for SLAC's final experimental plan as it is now.
In terms of time, squeeze yourself to the extreme.
And even if Chen Zhou rejected Friedman, Cross felt that Friedman would not, and had no reason, to blame Chen Zhou.
The same goes for them, there is no reason to blame Chen Zhou.
However, when Chen Zhou chose to stand with them and go all out.
Cross was very moved.
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 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: "That's quite a lot, it's all the documents!"
Cross froze for a moment, but quickly said, "Leave it on me!"
