Frank Wilzek, who had just flown back to Boston from the CERN headquarters in Switzerland, got into the student's car.
After the car got on the road, the old professor sitting in the passenger seat put his laptop on the pushchair and connected to the wireless network. Just when he was about to take advantage of his free time to deal with work emails, he happened to receive an email from across the Pacific Ocean.
"Nothing..." After reading the end of the email, Frank frowned slightly and suddenly smiled and shook his head, "It's an interesting point of view, but I don't agree with it."
Damn it, my typing speed is a bit fast.
Far away in Jinling on the other side of the Pacific Ocean, Lu Zhou edited this paragraph and the processed data into an email, sent it to Frank Wilczek's mailbox, leaned on his chair and stretched.
It is this property that provided the theoretical foundation for the subsequent application of Deligne's tensor category theorem in physics.
There can be many things behind that characteristic peak, and the universe itself is not constructed by a single set of theories.
Lu Zhou squinted his eyes and read the email from beginning to end. Before he could think of how to refute, two more unread emails were thrown into his mailbox.
What on earth is going on
According to this theorem, elementary particles can basically be represented by irreducible units of Lie groups, and tensor products can be made on these representations. And this operation can exactly correspond to the particle bound state in physics.
Lu Zhou knew very well what Professor Frank meant. His hypothesis of the supersymmetric supplementary theory was in line with the framework formulated by Wigner's theorem. There was no big problem, it just lacked mathematical beauty.
Massachusetts, America.
Frank said casually while looking at the email.
"At present, the situation is quite optimistic. If the confidence level reaches 3sigma, it can be confirmed as a sign. CERN staff are checking instruments, cleaning orbits, holding press conferences, and leaving time for colleagues to publish papers. Waiting for early October The experiment is restarted. This month we will complete the theoretical part. Starting from next month, I will let you live in Geneva... huh? "
For example, as Lu Zhou said, Deligne's tensor category theorem cannot be used to explain the rationality of this extra dimension, although the possibility of its existence cannot be completely denied.
I believe that with Mr. Frank's magnanimity in extending an invitation to him for joint research regardless of his age, he would not care about such a trivial matter.
At this moment, he did not know that Mr. Frank had returned to MIT, nor did he know that he had just gotten off the plane. Otherwise, he would be even more surprised by this old man's enthusiasm for work.
A plane lands at Boston International Airport.
Isn't it amazing
Academic exchanges are not about ranking based on seniority. There is nothing to be polite about. It is what it is. Therefore, Lu Zhou pointed out the problems he discovered without being tactful.
Although he initially proposed that the signal in the 750 GeV energy region might come from supersymmetric particles in order to convince the old man, he was actually not that obsessed with supersymmetric particles.
If the old gentleman happens to be replying to emails right now, he probably won't have to wait too long to see the reply.
[If there is an extra dimension of compactification, then every field in the high-dimensional space corresponds to a zero-brane ordinary field in the four-dimensional space, plus infinite fields whose mass is inversely proportional to the compactification length. And the source of this field can just be used as the Fourier series of the original zero-brane field in the compact dimension!]
In the email, the young man from China wrote.
Lu Zhou opened the email and looked at the time in the lower right corner of the desktop, and was suddenly surprised.
Swiss time is six hours behind Beijing time. It's only five o'clock in the morning there right now, right
After all, this signal is weak enough. If it weren't for the accumulation of a large number of collisions, this clue might not be discovered. The reason why dark matter is difficult to observe is that it hardly interacts with other elementary particles, including photons.
"Professor, how is the situation at CERN?"
For a moment, he was speechless and didn't know what to say.
[But don’t you think that we can use a model that is more in line with mathematical aesthetics to explain the characteristic peaks existing in the 750GeV energy region? There is absolutely no need for us to introduce an extra dimension outside of a well-represented symmetry field to explain the source of its mass, and forcefully explain that it is a supersymmetric particle... What I mean is, is it possible that this is a kind of dark matter that we don't understand? particle?]
[The possibility you mentioned exists, but I think it is unlikely. I am certain that CERN's equipment is not advanced enough to stably observe dark matter. If the signals observed on the ATLAS and CMS detectors were dark matter, I am sure that the characteristic peaks of the two would not appear so consistent. If you have any questions about this, you can consult Mr. Lynn Evans. Regarding my theory, I can also provide additional explanations.]
This theorem describes how symmetry principles in physical systems, such as rotation, translation or CPT operations, change the state of the Hilbert space.
The doctoral student sitting in the driver's seat glanced at the emails on the screen and asked casually.
[This kind of field should also exist for supersymmetric particles. It is precisely because of this relationship that the coupling between supersymmetric particles and fermions should be raised instead of being suppressed by the Planck energy scale. I think in theory this makes sense. So according to this theory, we should be able to find supersymmetric particles at energy scales below TeV, so you can have more confidence in the LHC.]
Dark matter particles are what Lu Zhou thinks are most likely.
[Dear Professor Frank, I have some questions about the supplementary theory of supersymmetry you proposed. According to Deligne's tensor category theorem, we can know that a category that satisfies certain conditions must be a representation category of the supersymmetry group G, so we can say that supersymmetry is a relatively natural extension of field theory, but in the supplement you proposed In the theory, it is assumed that there is an extra dimension beyond the representation of the symmetry field to explain the reason why the supersymmetric particle has an excessive mass. Does this violate Deligne's tensor category theorem?]
After pressing the reply button, Lu Zhou was no longer in a hurry to eat, but leaned on his chair and waited quietly.
[LU: The attachment has been received. In addition, regarding your question, I admire your mathematical physics skills, but my suggestion is that you'd better review the expression of Wigner's theorem in quantum mechanics, and you will understand my supplementary theory of supersymmetry. There is nothing wrong with the assumptions made.]
However, the old gentleman's reply was also tactless...
The old gentleman is so confident in his theory, and what he says is well-founded.
Hold the grass, does this old gentleman get up so early
The reply in the email was simple, mainly answering his questions.
When he saw the sender's name, he raised his eyebrows with interest and clicked on the email to read it.
However, this first email only hacked CERN's equipment, and the last email gave him more confidence in CERN's collider...
Seeing that the professor suddenly stopped talking, the doctoral student asked, "What's wrong?"
Sure enough, not long after waiting, an email popped out.
Mathematics and physics are organically combined with a theorem as a link.
Lu Zhou thought for a while, put his hands on the keyboard, and entered his thoughts.
Just when he was about to get up to eat, an unread email suddenly appeared in his mailbox.
As a researcher in theoretical physics, Lu Zhou certainly knows Wigner's theorem, which is the cornerstone of the mathematical expression of quantum mechanics.
After staring at the three emails for a long time, Lu Zhou didn't move his hand on the keyboard.
