Chapter 1325 An Unresolved Controversy

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 century-old problem of physics, this guy actually got a whiteboard.

What is he trying to do?

Is it possible to find here the method of applying the "Type-III Seesaw mechanism" to solve the problem of the origin of neutrino mass, so as to prove that the problem raised by oneself is not worth mentioning at all?

How is this possible? !

Professor Felix was almost amused by the outlandish idea.

If this problem is really so easy to solve, the physics community will not be at a loss for the mysterious neutrino so far.

Not paying attention to the weird expression on Professor Efelix's face, Lu Zhou stood up from the chair and walked to the whiteboard in a leisurely manner.

"Thanks."

After throwing a tip of 100 RMB to the waiter, Lu Zhou, who was standing in front of the whiteboard, picked up the marker pen hanging on it.

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

The pen tip swished across the whiteboard, and Professor Felix just stared at it intently.

Although there was not a lot of movement, such a large whiteboard in the coffee shop is indeed a bit conspicuous.

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

There are countless halos piled up on the top of the head, even if you want to ignore this person, it is difficult.

Gradually attracted attention by the content on the whiteboard, many people left their seats and gathered towards this side in groups full of curiosity.

"What is Professor Lu writing?"

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

"No, no! It's the Seesaw mechanism! If I'm not mistaken...he's explaining the origin of the neutrino's mass!"

As soon as these words were uttered, it was like dropping a bomb towards the calm lake, instantly igniting the nearby air.

"hiss--!"

"The origin of the mass of neutrinos?!"

"Isn't it? This kind of thing...can be explained clearly with a whiteboard?"

"Awesome! It's a blockbuster!"

For a place like IMCRC, the coffee shop itself is a place to communicate and discuss academic issues, so no one cares whether it is too noisy here.

Attracted by the crowd's voice, more and more people gathered towards this side.

Looking at the smooth calculation formula 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 shocked instantly.

I don't know when it started, there was a circle of people around the whiteboard, and it was so 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 quite 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 naturally he would not be affected by nearby people and sounds.

The realm of LV10 is very mysterious.

The line-by-line formula seems not to be a formula, but a spell woven from the words of the gods. Although it does not have the energy to move the wind and rain, it dominates and affects the changing laws of everything in the universe.

Whenever he enters this state, Lu Zhou can't help feeling a little bit emotional.

No wonder math grades determine the upper limit for grades in other subjects.

Without the support of LV10 mathematics level, I am afraid that even he would find it difficult to control this language of communicating with the universe...

Just like that, time passed by every minute and every second. When he squatted down in front of the whiteboard and wrote the last line of calculations, Lu Zhou straightened up and took half a step back.

Looking at the calculation formulas stuffed on the whiteboard, with a satisfied smile on his face, he nodded slightly.

"good."

After speaking, Lu Zhou turned around, looked at Professor Felix who was sitting on the chair, who was completely dumbfounded, and continued.

"The answer you want is here. I think these calculations are enough to tell you why your paper was rejected in the review meeting."

"Wait a minute," Professor Felix blushed and hurriedly said as he watched Lu Zhou put down the marker pen, "I still don't quite understand. What did you do? You can... tell me ?"

As much as hate to admit it, it is the truth.

Halfway through Lu Zhou's writing on the blackboard, he was completely thrown off by the smooth flow of thinking, and no matter how hard he tried, he couldn't keep up with his rhythm.

This sentence was recognized by many people nearby, and voices of agreement gradually spread around.

Obviously, it's not just that Professor Felix didn't keep up with the rhythm of Lu Zhou's blackboard writing, it's the same with them around here.

"Of course, I'm actually going to do it," Lu Zhou smiled faintly, turned to look at the content on the whiteboard, spent about three seconds to organize the language, and then said, "Chinese It is true that the dynamics of the origin of micron mass is the frontier hotspot of high-energy physics research in recent years, but not all research directions are possible."

"Currently, fermions have two possible mass terms, the Majorana mass term and the Dirac mass term."

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

"However, our observations of phenomena such as the anisotropy of the cosmic microwave background radiation show that the absolute mass of neutrinos should be less than 0.2eV. Considering that the mass of the top quark is 172GeV, it is obvious that only the Higgs mechanism is used to explain this Fermion mass spectrum with huge drop is very difficult and unnatural!"

"So now it is more common to treat neutrinos as Majorana particles, so that we can use the Seesaw mechanism to study the origin of neutrino mass—"

"That's right!" Responding to this sentence, Professor Felix instantly cheered up, "Is there any problem with my thesis? Didn't I express it like this?"

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

"Don't rush to be happy, I haven't finished my words. It is indeed attractive to use the Seesaw mechanism to study the mass origin of neutrinos, but the Seesaw model of the TeV energy scale will lead to the destruction of the unitarity of the lepton-flavor mixing matrix... ...Have you considered this question?"

Whispering sounds spread from around.

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

Confused by these words, Professor Felix froze there, and it took a long time for him to slowly come back to his senses.

"The Seesaw model of the TeV energy scale will lead to the destruction of the unitarity of the lepton-flavor mixed matrix... There seems to be such a debate in the physics world, but it is just a conjecture, how do you know it must be right—"

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

There was an uproar.

The moment they heard these words, the onlookers went crazy.

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

Although some people had been videotaping the whole process before, people's reactions were far less fanatical than they are now.

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

Just use a whiteboard like this? !

How can it be!

"It's impossible..." Speaking everyone's thoughts, Professor Felix stared blankly at the calculation formula on the whiteboard, and couldn't say anything more, just kept repeating the phrase "this impossible."

If the Seesaw model of the TeV energy scale can lead to the destruction of the unitarity of the lepton-flavor mixing matrix, then the Type-III Seesaw mechanism is not the best solution to the origin of neutrino mass.

So what has he been researching all this time? !

Thinking of this, a sad look appeared on Professor Felix's face.

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

Not a submission to academic authority.

It was only after those few sentences on demand that he had gradually begun to understand the calculations on the whiteboard, and gradually realized that what Lu Zhou said was true.

However, he couldn't accept this reality at all.

For nearly a decade, he's been working on the Type-III Seesaw mechanism, trying his best to find that piece of the puzzle that fills in the neutrino's mass source.

But the facts in front of him now tell him that he has just 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 a life have?

In particular, the golden age for a person to engage in scientific research is only twenty or thirty years in total.

"Sometimes...that's how it is," Lu Zhou paused for a moment, looking at Professor Felix, who was ashen-faced, and continued, "The truth is always hard to accept, because it's usually not sweet words."

"The Seesaw mechanism may be a suitable idea, but fatal loopholes make it almost impossible to reach the end of this road."

"……what should I do."

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

"Although the Seesaw mechanism has many problems, I believe it is also an opportunity for you."

"Why not try to adjust the Seesaw mechanism combined with the Leptogenesis mechanism? This model can well explain the tiny mass of neutrinos and the asymmetry of baryons in the universe, and can pass the norm in the Large Hadron Collider interaction, which makes it possible to test the mechanism experimentally...and these are things that the Seesaw mechanism does not yet have."

Looking at the pupils that were gradually glowing, Lu Zhou smiled lightly and said.

"...Although I can't explain why for a while, but as an alternative, I recommend that you start from this aspect and think more about it."

"Maybe, something different can be found."
