Solved?!

Director Sun and Professor Guo were a little confused. They looked at the serious-looking Xu Mang in surprise. They really understood what the sentence just meant and it made sense... They just flipped through it a few times and read a few words at most.

, as a result, Academician Xu Mang said that he had solved it.

What to solve?

Solve the difficult problems of klystron oscillator?

"Xu..."

"Academician Xu?" Director Sun asked curiously: "You... you just said you have solved them all? What problems have you solved? Is... is it a problem encountered by Professor Guo's team? This...

.This...there are a lot of questions, are you...are you kidding me?"

Xu Mang shrugged and said calmly: "The core of the problem you encountered is that you don't know or understand the role of scattering amplitude. I think...Professor Guo is not a person in this field, right? You are more of a

Were you forced in?"

Professor Guo was a little embarrassed. Unlike what Xu Mang said, he was truly an expert in this field, but...he had no idea that scattering amplitude would be involved...

"I..."

"I am in this field...but I really didn't expect it to be related to the scattering amplitude." Professor Guo said helplessly: "Academician Xu...what is going on?"

"oh..."

"It's quite simple." Xu Mang said calmly: "Scattering amplitude is one of the core physical quantities of quantum field theory, and quantum field theory is booming with accelerators in particle physics, and the corresponding quantum field theory has also been developed, so scattering

Amplitude is the bridge between theory and high-energy experiments."

"I took a look at your files."

"You seem to have thought of the scattering amplitude, but there is no remaining research...A traditional method is used to calculate the scattering amplitude." Xu Mang said calmly: "In principle, it can be applied to the calculation of any circle diagram, but then

As the number of outer lines or turns increases, the actual calculation is often very complicated."

Professor Guo nodded and said seriously: "Yes... we thought about using another method to achieve greater simplicity, but... we found that the maximum degree of transcendence still exceeded simplicity and commonality.

Adaptability.”

Xu Mang smiled: "Let me guess... you used the tree diagram amplitude formula containing any number of gluons."

After hearing Xu Mang's words,

Professor Guo was completely stunned. He didn't say what methods he used at all, but Academician Xu got the answer directly. This...is this too exaggerated?

Director Sun, who was standing next to him, also had a frightened expression. Although he was not an expert in this field, he knew something about it. Xu Mang was able to analyze what Professor Guo had used just from other people's words.

The way you envisioned it, what a strength it is.

"right!"

"We once really wanted to use the amplitude formula of the tree diagram containing any number of gluons... to understand the amplitude and even the quantum field theory." Professor Guo said seriously: "But... we cannot solve many problems in it at all.

"

"Of course!"

"Because this is related to the mathematical structure of amplitude in field theory." Xu Mang said calmly: "Generally speaking, the result of the amplitude of the loop diagram can be expressed by Feynman integrals, but the numbers that appear in Feynman integrals are not

It is not arbitrary, but corresponds to what is called stages in mathematics."

"so..."

"Common mathematical functions do not appear in Feynman integrals, such as trigonometric functions, exponential functions, and double log functions." Xu Mang said: "The more common mathematical functions that belong to Feynman integrals are polylogarithmic functions and Riemann Zeta numbers.

.”

"I see!"

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

Xu Mang raised his head and took a look, and said slowly: "No... you still don't know. What I just said is just the surface, not the core... The reason is very simple, because the correspondence between these amplitudes you think of

relationship, only the case of pure gluon outer lines is considered."

"I ask a question!"

"In the standard model of supersymmetry, in addition to gluons and quark particles, the amplitude of outer lines containing quarks is equally important in physics." Xu Mang said calmly: "Then...do they also have a similar maximum degree of transcendence relationship?

Woolen cloth?"

this...

This is so hard to answer!

Professor Guo fell into deep thought, thinking about how to answer Xu Mang's question.

"Well..."

"I think it's unlikely." Professor Guo said: "First of all, the structures of quarks and gluons are very different. Quarks are fermions and gluons are bosons. Secondly... the gauge group representations of gluons and quarks are also completely different.

.”

"Gluons are adjoint representations, while quarks are basic representations, which means they are very different in color structure." After Professor Guo finished speaking, he asked cautiously: "Academician Xu... what do you think?"

"With just a simple transformation of the color factor, the maximum transcendence part of the quark amplitude and the gluon amplitude are completely equivalent." Xu Mang said with a smile: "Of course... this is just a preliminary calculation of mine. Just now

I calculated it in my mind and found that it is feasible."

"???"

"???"

What's the meaning?

I just calculated it in my mind, this... the amount of calculation is a bit big!

Director Sun and Professor Guo were a little at a loss. They were a little confused by Xu Mang's words. From a rational point of view, this was simply impossible... but if this person was Xu Mang, it might be possible.

And that's just maybe...

"Are you curious?" Xu Mang said with a smile: "Let's do this... I will solve this problem, and then you will solve it yourself. I will give you at most one month. If it exceeds one month, there will still be no progress.

If it reaches more than 30%, I will cancel the cooperative relationship with you and will pursue relevant responsibilities."

"certainly."

"I'm just trying to figure out who... was behind it, fueling the fire and letting you get this project." Xu Mang said calmly.

for a moment,

The atmosphere in the office condensed, and Director Sun felt unprecedented pressure. Sure enough... Academician Xu Mang suddenly came here, it must be to solve this matter... It's basically over now. If there is an investigation, it will

It involves many problems.

At this time,

Xu Mang suddenly got up and walked towards the door silently. However, when he reached the door, he suddenly stopped and said to Director Sun behind him: "Director Sun... I have something that I need to communicate with you. I hope you can come out.

one time."

"OK!"

Watching the two people leave,

Professor Guo vaguely felt something strange. He had heard before that Academician Xu Mang proposed a plan to change the environmental framework, and it was unanimously approved... But his sudden arrival here today is related to changing the scientific research framework?

possible!

This institute...has a big problem, and this problem...I believe that similar situations exist in various institutions across the country.

...

"Academician Xu?"

"you..."

"What's the matter with you?" Director Sun asked.

"oh..."

"Actually, it's nothing." Xu Mang said with a smile: "I heard that there is a big crack within you. I want to ask... what kind of crack is this crack? Don't use some lies to excuse me. This matter

This matter...is not a secret matter in your city."

"..."

"this..."

"Actually, it's because of...funding issues." Director Sun said cautiously, "Because our funds...are only enough to sustain two or three projects."

"Such a small amount of funds?"

Xu Mang's face darkened and he asked, "Since there is such little funding...why do you have so many people in your research institute?"

"Because our institute had six or seven projects a few years ago... It was only as time went by that these projects were completed, but the follow-up was not followed up, which led to..." Director Sun sighed and silently

He said: "Academician Xu... we also have difficulties."

It sounds pitiful, but Xu Mang didn't sympathize with him at all, because it was not the case... He just received Xiaoman's WeChat message, and the content above made Xu Mang a little helpless.
