Massachusetts, America.

A plane landed at Boston International Airport.

Frank Verzek, who had just flown back to Boston from the Swiss headquarters in ern, took the student's car.

After the car was on the road, the old professor sitting in the co-pilot position put the laptop on the push and connected to the wireless network. Just as he was ready to take advantage of the free time to process the work email, he just received an email from across the Pacific.

Seeing the sender's name, his eyebrows picked it up with interest and opened the mail and looked up.

The doctoral student who was driving in the driver's seat, scanned the email on the screen and asked casually.

"Professor, what happened to the ern side?"

As he looked at the mail, Frank said casually.

"At present, the situation is still optimistic. The confidence level can be confirmed as sigma. The staff of ern are checking the instruments, clearing the track, opening a press conference, and leaving time for the water papers for the peers. Waiting for the beginning of October. The experiment restarts, this month we have to complete the theoretical part, I will let you live in Geneva from next month... eh?"

Seeing that the professor suddenly did not speak, the doctoral student asked: "What happened?"

"Nothing..." At the end of the message, Frank frowned and frowned. He suddenly shook his head with a smile. "It’s a very interesting point, but I don't agree."

In the mail, the young man from China wrote.

[Respected Professor Frank, I have some questions about your supplementary theory of supersymmetry. According to the Deligne tensor category theorem, it can be known that the category satisfying certain conditions must be a representation of a supersymmetric group g, so we can say that supersymmetry is a generalization of the field theory, but in your supplement In theory, it is assumed that there is an extra dimension beyond the symmetry field representation to explain the reason why the supersymmetric particle is too large. Does this contradict the Deligne tensor theorem? 】

Academic exchanges are not on the rankings of seniority, there is nothing polite, what is what, so for the problems found, Lu Zhou pointed out that there is no euphemism.

I believe that Mr. Frank's ability to propose a joint research invitation to him regardless of his age will not be considered in such a small matter.

However, the reply of the old gentleman is equally euphemistic...

Far from the Jinling on the other side of the Pacific Ocean, Lu Zhou edited the passage and the processed data in an e-mail and sent it to Frank Welzek's mailbox, leaning against the chair and stretching.

Just when he was just about to get up and go to dinner, suddenly an unread e-mail appeared in his mailbox.

Lu Zhou clicked on the e-mail to see it, and looked at the time in the lower right corner of the desktop, suddenly surprised.

Holding the grass, is this old gentleman getting up so early?

Switzerland is six hours behind Beijing time. Is it only five o'clock in the morning?

At this moment, he did not know that Mr. Frank had returned to MIT, and he did not know that he had just got off the plane. Otherwise, he would be even more surprised by the work of the old gentleman.

The reply in the email is very simple, mainly to answer his questions.

[lu: The attachment has been received. In addition, regarding your doubts, I admire your knowledge of mathematics and physics, but my suggestion is that you should review the expression of Wigner's theorem in quantum mechanics, and you will understand my theory of supersymmetry supplement. There are no problems with the assumptions made. 】

As a theoretical physics research, Wigner's theorem Lu Zhou certainly does not know, this is the cornerstone of the mathematical expression of quantum mechanics.

This theorem describes the principle of symmetry in physics systems, such as how rotations, translations, or pts change the state of the Hilbert space.

According to this theorem, elementary particles can basically be represented by the irreducible 酉 of the Lie group, and a tensor product can be made for these representations. And this operation, just in time, can correspond to the physical particle bound state.

Is it amazing?

Mathematics and physics, with a theorem as a link, organically combined.

It is this nature that provides a theoretical cornerstone for the later application of the Deligne tensor category theorem in physics.

Lu Zhou is very clear about Professor Frank's meaning. His hypothesis of supersymmetric complement theory is in line with the framework of Wigner's theorem. There is no big problem, just lack of mathematical beauty.

For example, as Lu Zhou said, it is impossible to explain the rationality of this extra dimension by using the Deligne tensor category theorem, although it is impossible to completely negate the possibility of its existence.

Lu Zhou thought about it, put his hands on the keyboard and entered his own thoughts.

[But don't you think that we can use a model that is more in line with mathematical aesthetics to explain the characteristic peaks that exist in the 750gev energy region? There is absolutely no need to introduce an extra dimension outside of a fully symmetric field to explain his source of quality, forcibly indicating that it is a supersymmetric particle... I mean, is this possible to be something we don't understand? Dark matter particles? 】

Although he originally proposed to signal the old 750gev energy zone, it may come from supersymmetric particles, but in fact he is not so persistent about supersymmetric particles.

There can be many things behind that characteristic peak. The universe itself is not built by a single set of theories.

The dark matter particles are what Lu Zhou feels most likely.

After all, this signal is weak enough. If it is not a large number of collisions, this clue may not be discovered. Dark matter is difficult to observe because it hardly interacts with other elementary particles, including photons.

After pressing the reply button, Lu Zhou was not in a hurry to eat, but leaned on the chair and waited quietly.

If the old gentleman is now returning to the mail, he probably won't have to wait too long to see the reply.

Sure enough, it didn't take long for an email to jump out.

[The possibility that you said is there, but I think it is unlikely. I can be sure that ern's equipment is not advanced enough to observe dark matter. If the signals observed on the atlas and ms detectors are dark matter, I'm sure that the characteristic peaks of the two will not be so consistent. If you have any questions, you can consult Mr. Lynn Evans. And for my theory, I can also add a supplementary explanation. 】

Lu Zhou blinked his eyes and saw the e-mail from the beginning. He didn't think about how to refute it. He also threw two unread e-mails into his mailbox.

[If there is an extra dimension of compaction, then each field in the high-dimensional space corresponds to a normal field of zero-film in the four-dimensional space, plus an infinite number of fields that are inversely proportional to the length of the compaction. And the source of this field can be used as the Fourier series of the original zero film field in the compaction dimension! 】

[Super-symmetric particles should also exist in this field. It is in this relationship that the coupling of super-symmetric particles with fermions is not low by Planck's energy, but should be raised. I think this makes sense in theory. So according to this theory, we should be able to find supersymmetric particles in the energy mark below tev, so you can have more confidence in lh. 】

Holding the grass, the typing speed is a bit faster.

However, this first email only darkened an ern device, and the last email gave him confidence in the ern collider...

What the **** is this?

I stared at the three emails and watched it for a while. The hand that Lu Zhou had placed on the keyboard did not move.

The old gentleman is so confident in his theory, and he is justified.

For a time, he was a bit dumb and didn't know what to return.
