Chapter 1230

Solution...

solved?!

Director Sun and Professor Guo were a little confused. They looked at Xu mang with a serious face in surprise. They didn't understand what the sentence just said. They were reasonable. They just looked through a few words at most. As a result, academician Xu mang said that he had solved the problem.

What to solve?

How to solve the problems of klystron oscillator?

"Xu..."

"academician Xu?" Director Sun asked curiously, "you just said that you have solved all the problems? Solved those problems? Is it... Is it the problem of Professor Guo's team? This... This... There are many questions. Are you... Are you kidding? "

Xu mang shrugged his shoulders and said calmly, "the core of the problem you have encountered is that you do not know or understand the effect of scattering amplitude. I think... Professor Guo is not a person in this field, right? Are you more forced to come in? "

Professor Guo has some embarrassment. Different from what Xu mang said, he is really an expert in this field, but... He did not expect that the scattering amplitude would be involved...

"I..."

"I am in this field... But I really didn't think it was related to the scattering amplitude." Professor Guo reluctantly said: "academician Xu... What is going on?"

"Oh..."

"it's quite simple." "Scattering amplitude is one of the core physical quantities of quantum field theory. With the rapid development of quantum field theory in particle physics, the corresponding quantum field theory has also been developed. Therefore, scattering amplitude is a bridge between theory and high-energy experiment."

"I took a look at your papers."

"You seem to think of the scattering amplitude, but there's no remaining research... Using a traditional method to calculate the scattering amplitude." "In principle, it can be applied to the calculation of any cycle graph, but with the increase of the number of outer lines or cycles, the actual calculation is often very complicated," Xu said calmly

Professor Guo nodded his head and said seriously: "yes... We want to use another way to have great simplicity, but... We found that the part of maximum transcendence still exceeds simplicity and universality."

Xu mang smile: "let me guess... You used to use the tree graph amplitude formula containing any number of gluons."

After hearing Xu Mang's words,

Professor Guo was completely stunned. He didn't say that he had used those methods. As a result, academician Xu got the answer directly. This is too exaggerated, isn't it?

Sun Suo Chang, who stands on the edge, is also frightened. Although he is not an expert in this field, he knows a little bit more or less. He can analyze the method that Professor Guo used to conceive from the words of others. What strength is this.

"Yes

"We really wanted to use the tree graph amplitude formula with any number of gluons... To understand the amplitude and even quantum field theory." Professor Guo said seriously, "but we can't solve many problems."

"Of course

"Because it has something to do with the mathematical structure of amplitude in field theory." "Generally speaking, the result of loop amplitude can be expressed by Feynman integral, but the number appearing in Feynman integral is not arbitrary, but corresponds to the so-called stage in mathematics."

"So..."

"common mathematical functions will not appear in Feynman integral, such as trigonometric function, exponential function, and double log function." "It belongs to Feynman integral and is more of a multiple logarithmic function and a Riemann zeta number," Xu said

"I see!"

"I think I know what the problem is." Professor Guo was suddenly enlightened.

Xu mang looked up and said slowly, "no, you still don't know. What I said just now is just the surface, not the core... The reason is very simple, because the corresponding relationship of these amplitudes you think of only considers the external line of pure gluon."

"I ask a question!"

"In the standard supersymmetric model, in addition to gluons, there are quark particles, and the amplitudes of the lines containing quarks are equally important in physics." Xu said calmly, "so... Is there a similar maximum transcendence relationship for them?"

This...

this is too difficult to answer!

Professor Guo was lost in thought. He was thinking about how to answer Xu Mang's question.

"Er..."

"I don't think it's possible." "First of all, quarks and gluons have very different structures, quarks are fermions, gluons are bosons, and... The gauge group representations of gluons and quarks are completely different," Guo said

"Gluons belong to the adjoint representation, while quarks belong to the fundamental representation, which means that the two are quite different in color structure." Professor Guo then asked cautiously, "academician Xu... What do you think?"

"Only a simple transformation of the chromatic factor is needed, and the maximum transcendence part of quark amplitude and gluon amplitude is completely equivalent." Xu mang said with a smile: "of course... This is just my preliminary calculation. I have just calculated it in my mind and found that it is feasible."“？？？”

“？？？”

What do you mean?

I just calculated it in my mind. This is a bit of a big calculation!

Director Sun and Professor Guo are at a loss. They have some doubts about Xu Mang's words. From a rational point of view, this is impossible to achieve... But if this person is Xu Mang, it may be possible.

And it's just maybe...

"do you feel curious?" Xu mang said with a smile: "well... I will solve this problem, and then you can solve it by yourself. I will give you one month at most. If it is more than one month, and the relevant progress is still not more than 30%, I will cancel the cooperation with you and pursue the relevant responsibilities."

"Of course."

"I'm just trying to figure out who... Helped you get the project." Xu mang said calmly.

In a flash,

the atmosphere in the office congealed, and director Sun felt unprecedented pressure. As expected, academician Xu mang came here suddenly to solve this problem. This is basically over. If the investigation is carried out, many problems will be involved.

At this time,

Xu mang suddenly got up and walked quietly to the door. However, when he got to the door, he suddenly stopped and said to director Sun behind him: "director Sun... I have some things to communicate with you. I hope you can come out."

"Good!"

Looking at the two people's departure,

Professor Guo vaguely felt a bit different. He had heard that academician Xu mang had proposed a plan to change the environmental framework, and it was approved by all... But today, is his sudden arrival here related to the change of scientific research framework?

Maybe!

This Institute... Has a big problem, and this problem... I believe that there are similar situations in various institutions across the country.

...

"academician Xu?"

"You..."

"what can I do for you?" Director Sun asked.

"Oh..."

"it's nothing." Xu mang said with a smile: "I heard that there is a big crack inside you. I want to ask... What kind of crack is this crack? Don't use some lies to prevaricate me. This matter... In your city, it's not a secret thing."

"..."

"this..."

"in fact, it is due to the problem of funds for..." Director Sun carefully said: "because our funds... Only enough to maintain two or three projects."

"So little money?"

Xu Mang's face darkened and asked, "since there are so few funds... Why do you study so many people?"

"Because a few years ago, our research institute had six or seven projects... But with the passage of time, these projects were completed, but the follow-up was not followed up, which led to..." Sun sighed and said in silence: "academician Xu... We also have difficulties."

It sounds pitiful, but Xu Mang and Ben didn't sympathize with him, because it was not the case... He just received Xiaoman's wechat, and the content above made Xu mang feel helpless.

In fact,

this problem is similar to what we have known before... The root cause is that the relevant leaders blindly expand, do not consider the future prospects, take advantage of the situation of funds, set up various projects randomly, and then recruit all kinds of people... To have a strong appearance, but internal fragile feeling.

Any slight change in the environment will result in huge cracks, which cannot be made up at all.

Moreover,

any researcher has a strong sense of belonging to a research institution and has a good expectation for the future, and this premise... Depends on the fact that research institutions respect talents from all aspects, increase their sense of gain and attach importance to their ideas.

Unfortunately,

what we can see from the current situation is another scene, which leads to the phenomenon that many research institutes leave their jobs on a large scale. This also happens to explain a truth, hoping to prove themselves and gain respect.

Yeah!

Some of the vines entangled in scientific research institutions and talents will be eliminated. Then, taking this opportunity, we can straighten out all kinds of relations and realize win-win and emotional resonance.

Thinking of this,

Xu mang suddenly realized that he had left too much time for those people? Three months... Three months later, Xu Yang and Xu man are going to the nursery age!

No way!

We should be unprepared for a month. We should start to act the next day when we have a sense of crisis. And after a month, we basically belong to the type of people who are facing the attack. This kind of person has a special kind of hard head, does not hit the south wall and does not turn back.Sorry...

Xu's south wall is not made of bricks!

"Director Sun..."

"I would like to ask you... Who gave you the klystron oscillator project?" Xu Mang's expression suddenly became serious and asked seriously.

"This..."

"this..." director Sun took a look at Xu mang. After a long silence, he said, "academician Xu... I can only provide you with a list. Many people in this list have infiltrated into the project of the collider and seek their own interests in it."

Xu mang didn't feel any surprise when he heard this. On the contrary, he would be very surprised if no one made small moves in it.

"Good!"

"You give it to me now!" Xu Mang's expression is still so calm.

However,

soon... Xu was not calm.

Xu Mang: (* ~ ＾)

I really want to take them to climb the mountain!

Kill them!
