Looking at the whiteboard dragged by the waiter, Professor Felix was stunned.

Faced with his own doubts about the fairness of the selection of the 100-year physics century question, this guy actually let people drag a whiteboard.

What the hell is he trying to do?

Is it possible to find a way to solve the problem of the origin of neutrino masses by applying the "Type-IIIseesaw mechanism" here, so as to prove that the problem you are proposing is not worth mentioning at all?

How is this possible?!

Professor Felix was almost amused by the strange idea.

If this problem were to be solved so easily, the physics community would not have been helpless against the mysterious neutrinos so far.

Not paying attention to the strange expression on Professor Felix's face, Lu Zhou, who got up from his chair, walked leisurely to the whiteboard.

"Thank you."

Throwing a tip of 100 RMB to the waiter, I saw Lu Zhou, who was standing in front of the whiteboard, casually picked up the marker hanging on it.

After thinking about it for less than half a minute, he printed the tip of the pen in his hand and unhurriedly wrote on the whiteboard.

The tip of the pen scurbled across the whiteboard, and Professor Felix stared intently.

Although there is not a lot of movement, such a large whiteboard in the café is really a bit conspicuous.

Especially the person standing in front of the whiteboard is the chairman of the IMCRC of Lu Zhou! Nobel Laureate in Physics! The creator of hyperspace theory!

Countless halos were piled up on top of his head, and it was difficult to ignore this person.

Gradually, attracted by the content on the whiteboard, many people left their seats, and with a stomach full of curiosity, they gathered in groups of three or five.

"What is Professor Lu writing?"

"The expression of the majorana mass term and the Dirac mass term should be the mass of fermions"

"No, that's not right! It's a seesaw mechanic! If I'm not mistaken...... He is explaining the mass origin of neutrinos! ”

As soon as these words came out, it was like dropping a bomb on the calm surface of a lake, instantly igniting the air nearby.

"Shhh

"Mass origin of neutrinos?!"

"Isn't it? This kind of thing...... Is it possible to explain it clearly with a whiteboard? ”

"Awesome! It's a bunker! ”

For a place like IMCRC, the café itself is a place to exchange and discuss academic issues, so no one cares if it's too noisy.

Attracted by the loud voice, more and more people gathered in this direction.

Looking at the flowing equations on the whiteboard, Professor Felix swallowed.

In order to demonstrate the embarrassment that he couldn't fully understand at this moment, he looked away and looked around, but this look didn't matter, and he was taken aback in an instant.

I don't know when it started, there was already a circle of people around the whiteboard, and it was blocked that I couldn't see the way out.

At the same time, Lu Zhou, who was standing in front of the whiteboard, had a rather calm expression on his face.

From the moment he entered the state, his attention was completely focused on the whiteboard in front of him, so he was naturally not affected by the people and voices nearby.

The realm of lv10 is very mysterious.

It was as if the line of arithmetic was not an arithmetic, but a spell woven from the words of the gods. Although it does not have the energy to call for wind and rain, it dominates and influences the laws of change in the universe.

Whenever he enters this state, Lu Zhou can't help but feel a little emotion in his heart.

It's no wonder that math grades determine the upper limit of grades in other subjects.

If he didn't have a lv10 math level to support it, I'm afraid even he would have been able to control this kind of language that communicates the universe......

In this way, time passed minute by minute, and when he squatted down in front of the whiteboard and wrote the last line of the equation, Lu Zhou straightened up and took half a step back.

Looking at the equations stuffed with a whiteboard, he nodded lightly with a satisfied smile on his face.

"Not bad."

As he spoke, Lu Zhou turned around and looked at Professor Felix, who was sitting in his chair, completely dumbfounded, and continued.

"Here are the answers you want. I think these calculations are enough to tell you why your paper is being screened out in the review meeting. ”

"Wait a minute," Professor Felix said hurriedly as he looked at Lu Zhou, who had put down the marker, and hurriedly said, "I still don't quite understand. You...... What was done? OK...... Tell me about it? ”

I hate to admit it, but that's exactly what it is.

Halfway through Lu Zhou's board book, he was completely thrown off by this smooth train of thought, and no matter how hard he tried, he couldn't keep up with his rhythm.

This sentence was recognized by many people in the vicinity, and echoing voices gradually spread around them.

Obviously, it wasn't just Professor Felix who didn't keep up with the rhythm of the Lu Zhou board book, but they were also in the vicinity, and they only knew a little bit about it.

"Of course, in fact I was about to do this," smiling faintly, Lu Zhou turned to look at the content on the whiteboard, took about three seconds to organize the language, and then spoke, "The dynamics of neutrino mass origin is a frontier hot spot in high-energy physics research in recent years, which is indeed true, but not all research directions are possible. ”

"At present, there are two possible mass terms for fermions, which are the majorana mass term and the Dirac mass term."

"If the neutrino is a Dirac particle, the mass of the neutrino can be given directly by the Yukawa interaction."

"However, our observations of phenomena such as the anisotropy of cosmic microwave background radiation suggest that the absolute mass of neutrinos should be less than 0.2 EV. Considering that the mass of the top quark is 172 gev, it is obviously very difficult and unnatural to use the Higgs mechanism alone to explain the fermion mass spectrum with such a large drop! ”

"So it's more common nowadays to think of neutrinos as majorana particles, so that we can use the Seesaw mechanism to study the origin of neutrino mass."

"That's right!" Reacting to this sentence, Professor Felix instantly became energetic, "Is there anything wrong with my paper?" Isn't that what I say? ”

Looking at the excited Professor Felix, Lu Zhou smiled and continued.

"Don't be in a hurry to rejoice, I'm not done yet, the use of the Seesaw mechanism to study the mass origin of neutrinos does have some appeal, but the TEV labeled Seesaw model will lead to the destruction of the unitivity of the lepton-flavored mixing matrix...... Have you thought about this question? ”

Whispering voices came from all around.

Obviously, Lu Zhou's statement caused a lot of controversy among the crowd.

Forced by this sentence, Professor Felix was stunned, and it took a long time before he slowly came back to his senses.

"The TEV scaled Seesaw model leads to the destruction of the unitivity of the lepton-flavored mixing matrix...... There seems to be such a debate in physics, but it's just conjecture, and how do you know it must be right?"

"It used to be conjecture," Lu Zhou raised his chin to the whiteboard behind him and said with a smile, "Now it's not." ”

An uproar spread.

The moment they heard this, the onlookers at the scene went crazy instantly.

Countless people took out their mobile phones from their pockets and snapped pictures of the contents on the whiteboard.

Although some people have been recording the whole process before, the reaction has been far less fanatical than it is now.

Settle a long-debated controversy in the physics community!?

Just use such a whiteboard?!

How can it be!

"This can't be ......" said everyone's thoughts, and Professor Felix stared blankly at the equation on the whiteboard, unable to say anything more, just repeating the phrase "This can't be." ”

If the TEV labeled Seesaw model leads to the destruction of the unitivity of the lepton-flavored mixing matrix, then the Type-IIIseesaw mechanism is not the best solution to solve the origin of neutrino mass.

So what is he doing all along?!

Thinking of this, the expression on Professor Felix's face appeared with sadness.

Although he wanted to deny Lu Zhou and wanted to stand up and loudly refute his views, his throat couldn't make a single sound of rebuttal at all.

Not a surrender to academic authority.

It's just that under the on-demand of those few sentences, he has gradually begun to understand the calculations on the whiteboard, and gradually realized that what Lu Zhou said is true.

It's just that he can't accept such a reality at all.

For nearly a decade, he has been working on the Type-IIIseesaw mechanism and trying to find the piece of the puzzle that would fill the source of neutrino mass as much as possible.

But now the facts in front of him tell him that he has only been spinning in a dead end for the past ten years, complacent about some meaningless achievements......

Looking at Professor Felix, who seemed to have lost his soul, Lu Zhou was silent for a while and sighed softly.

He could probably feel the frustration and sadness in his heart.

How many decades can there be in life?

In particular, the golden period when a person is most suitable for scientific research adds up to only twenty or thirty years.

"Sometimes...... That's it," Lu Zhou paused for a moment as he looked at Professor Felix, who was looking at him like a dead face, and continued, "Truth is always hard to accept, because it is not usually sweet words. ”

"The Seesaw mechanic may be a good idea, but a fatal flaw makes it almost impossible to reach the end of the road."

“…… What should I do. ”

"I'm afraid you have to ask yourself, after all, I'm not an expert in this area," looking at the lost Professor Felix, Lu Zhou thought for a while, and said, "If the tool is too embarrassing, try to repair it." ”

"There are a lot of problems with the Seesaw mechanic, but I'm sure it's an opportunity for you."

"Why not try tweaking the Seesaw mechanic with the LeptoGenesis mechanic? This model can well explain the problem of the asymmetry of the tiny mass of neutrinos and the number of baryons in the universe, and can be experimentally tested by gauge interaction at the Large Hadron Collider...... And these are all things that the Seesaw mechanism does not have for the time being. ”

Looking at the pupils that gradually glowed, Lu Zhou smiled faintly and said.

“…… Although I can't explain why for a while, as an alternative, I recommend that you start with this aspect and consider it more. ”

"Maybe you'll find something different."
