For the world of physics, nothing big has happened in a long time.
Even the discovery of the Zcs (3985) strange hadron at high energy is actually not a big event that can shock the entire physics community.
Because this new particle has actually been predicted by various existing models, it is only a matter of time before it is discovered. For the entire physics community, it is probably equivalent to making up for an already existing particle. Do you know what shape the puzzle is.
Its greatest significance is to verify the correctness of the past standard model.
Only the discovery of supersymmetric particles, which play an important role in the basic composition of the entire universe and can reveal new theories, is enough to shock physicists around the world, just like the original Like the Higgs particle.
Of course, this kind of thing can shock the world of physics experimentally, and it can shock the world of physics theoretically. The establishment of the Standard Model is one of them. In the same way, overthrowing the past Standard Model and establishing a When the new standard model comes out, it is definitely one of them.
However, the Standard Model has always been considered the most successful theory and has not made any mistakes for decades. Therefore, most physicists do not believe that the Standard Model can be overturned under the current circumstances.
Unless they really find supersymmetric particles or verify string theory.
But it is a pity that at the end of 2020, when all physicists were ready to welcome the new year, the paper on arxiv broke their stable mentality.
…
As the most cutting-edge research center in particle physics, CERN can be said to be the first to feel any disturbance in the particle physics world.
So, at CERN at the end of December, all the researchers stopped their research work, and the top experts in particle physics had very serious expressions throughout the day.
This sudden change caught ordinary researchers and intern researchers off guard.
"Do you know what happened? Today, Professor Davidson's expression seems to have been wrong since the morning. After lunch, he went to a meeting and has not come back. He has not asked people in our group to continue their research. This is rare. Got a holiday."
Several intern researchers who came here from China gathered together and chatted.
Another person said in surprise: "Is Professor Davidson like this too?"
"Yes, is it the same for you, Professor Clear?"
"Yes, we also have a holiday, and Professor Clear also went to a meeting."
"No wonder you all have time today."
"But what happened? The collider malfunctioned?"
"Probably not, otherwise there would have been a notice, right?"
"Anyway, I remember that when Professor Devinson told us about the holiday, he also said, 'There is no point in continuing research for the time being.'"
“Physics no longer exists?”
one person joked.
A group of people suddenly opened their minds.
"Is there a sophon in the LHC?"
"The Trisolarans are coming?"
"Sir, this way."
…
After a while of joking, someone finally said the reason: "I heard... It's just what I heard. It seems that there is a new paper on arxiv that has modified the previous standard model and mathematically Still can’t find the problem.”
"That is to say - although physics still exists, it is just to be torn down and then rebuilt."
"ah?"
After hearing this explanation, several other people's eyes widened in shock.
The standard model they had studied for so long was actually modified like this?
Oh my God!
This is no less than telling them that 1+1 is not equal to 2, but equal to 3!
"Real or false? Who wrote that paper? Is it Edward Witten?"
"No, you all should know the author's name, it's Li Mu."
"Li Mu?! Isn't he studying mathematics?"
For a moment, several other people were shocked again.
As Chinese people, Li Mu's name was of course well known to them.
It's just... Li Mu actually tore down the standard model of the past and then built a new one?
What a joke!
Suddenly, at this moment, a voice came: "Hey, Chen, that Li Mu in your country is simply God!"
Several people turned around and were stunned. This man's name was Guilliman Vern. He was one of the best young researchers at CERN. He was only thirty years old and had already made many important achievements. As a result, he was not only directly hired as a researcher by CERN, but also entered the list of candidates for awards such as the Max Planck Medal and the Dirac Medal. He is quite famous in the theoretical physics community.
The person Guilliman Vern called was Chen Ming. They knew each other because they had research experience in the same group before, but even then, they had not communicated much. Now Guilliman Vern actually Did you take the initiative to say hello to them?
Fern came to sit next to them and continued with excitement: "They say physics is God's game and mathematics is God's game rules, so Li Mu must be able to communicate with God! Otherwise, he would not be interested in this game. He knows the rules so well.”
"Oh! It's so crazy!"
Listening to Fern's excited words, Chen Ming and others looked at each other in confusion. Until finally, Chen Ming asked: "Fern, are you talking about the paper Li Mu posted on arxiv?"
"Yes!" Fern nodded, "It's the paper published yesterday. I spent one night studying this paper. Believe me, after reading it, you will definitely be like me. Excited!"
"this……"
Chen Ming and others felt that they needed to take a look at this paper immediately.
Suddenly at this moment, Fern's cell phone rang and he answered the call.
"There's a meeting? Mr. Chairman, is it convened? Do you want to focus on Li Mu's paper? Okay, okay, I understand, I'll come now."
Putting down the phone, Fern patted Chen Ming on the shoulder, "It's time for me to go. I suggest you and your friends read the paper in advance. Maybe it won't be long before we all have to study this new standard model. .”
Then he left here, probably going to a meeting that would have an impact on the entire physics community.
Chen Ming and the others who stayed where they were looked at each other.
Chen Ming stood up first and said: "I'm going back first, I have to read the paper."
Several other people also stood up.
"Me too."
"Let's go."
That's what theoretical physics is like.
Based on a framework established by a general theory, all scholars are also filling in this framework. Once the theory changes, the entire framework will change accordingly, and the scholars within it We must also adapt to the new framework.
Otherwise, those who cannot adapt to the new framework will have no choice but to be eliminated.
In just a few days, Li Mu's paper turned the entire physics world upside down.
Seventy to eighty percent of physicists are a little confused.
Wake up and their standard model is going to be a thing of the past?
And the non-perturbative method they have used for so long will become a thing of the past?
As for the paper…
Many of them have seen it, but the key is that they don't understand it.
Regarding the derivation process of the new expansion, some Fields Medalists like Deligne have said: "Let’s not discuss the correctness of the conclusion of this paper. From a mathematical point of view, this is definitely a Fields Medal. The award-level results and the process are hard not to remind people of Ramanujan - oh no, probably Ramanujan here would also be amazed by this."
Even if such a big shot says this, then they should stop trying to understand this paper.
What should I do if I don’t understand?
Let’s wait until the physics community comes to a unified conclusion.
However, thinking so, the big guys in the entire physics community have already started fighting over it.
The results brought by this paper are very subversive, but precisely because of its subversiveness, it has caused controversy.
Especially in the conclusion.
The new model's calculation of the mass of the W boson has become a key point of doubt for many experts.
Just like Witten's original attitude, this is tantamount to denying the experimental results.
Physics is an experimental science. Only experimental results can deny the theory, but there can be no theory that can deny the experimental results.
However, physicists who support this new theory have only one attitude: there are no problems with the mathematical derivation of this paper, so the conclusion is very trustworthy. Maybe there are still some problems with the past measurements of the W boson mass. What's the problem?
These physicists are very pure mathematical physicists. They always believe in the decisive role of mathematics in physics, so Li Mu's paper successfully convinced them.
Including Edward Witten, also stood up to express strong support.
In just one week, he reintegrated the past M-theory based on this new expansion, which directly made M-theory more perfect.
This is also the dawn he sees, which is to realize the "downward compatibility" of M theory, that is, it is compatible with those low-energy theories, that is, theories of molecules, atoms, protons, electrons, etc. This kind of theory only needs to use Collision experiments at lower energy levels can be tested.
The biggest problem with M theory is that it cannot use pure mathematics to solve non-perturbative problems. If it is solved, M theory, as the "ultimate theory", will be able to explain those low-energy experimental results.
Now, Li Mu's Li expansion has completely made non-perturbative problems a thing of the past in mathematics, which naturally has great significance for M theory.
"Now, M-theory has been perfected again, and non-perturbative problems can no longer stop us. As long as we achieve compatibility with low-energy theories, we will not need to discover strings to prove M-theory. Any existing Experimental data will help us prove the correctness of M theory."
"Li Mu's work and Li's development are worthy of celebration and cherishment by all of us, both in the physics community and in the mathematics community."
Edward Witten's declaration attracted support from the entire string theory school.
Li Mu's theory is like a ray of light in the darkness for all string theory scholars, illuminating their hope.
So of course they all showed great support.
In this way, the fierce debate made the entire physics community lively.
Just like the debate between quantum mechanics and relativity back then.
Until the end, people turned their attention to CERN.
As a holy place in today's high-energy physics community, bringing together half of the world's high-energy physicists, CERN's views on Li's development will have absolute guiding significance.
As a result, a full month later, CERN announced something to the entire physics community.
[Based on the paper "A New Standard Model Series Expansion" published by Li Mu on arxiv on December 29, 2020, CERN scholars have had a careful discussion and now CERN has made the following announcement to the physics community: We recognize the new expansion of the Standard Model in this paper and will use it as an important guiding theory in our future research. In future scientific plans, verifying the Li expansion of the Standard Model will also be our primary goal. Finally, I hope that particle physicists all over the world will take this new theory seriously. Changes in the world of physics sometimes happen overnight, and I hope everyone can keep up with the times. 】
The announcement of CERN amazed all physicists.
Because this already means that the Standard Model under Li's expansion has been officially accepted by the physics community.
From now on, Li Mu’s name will be imprinted on the milestone in the history of physics.
…
"Li Mu, the new model you created is now being studied by the entire Institute of High Energy."
"In addition, the Institute of High Energy's prediction of the Zcs (3985) neutral adjoint state particle in your paper has also been included in the top priority for the next stage. This time, we should be able to find it."
"You kid...are awesome."
On the phone, Academician Yue Lang said his last words with emotion.
Li Mu smiled and said: "I just did it by accident. "
"Is it a coincidence?" Yue Lang laughed for a moment, and finally said nothing more. "Anyway, I'm calling you just to tell you that you have graduated from my place. I have nothing to teach you." .”
"congratulation."
