Ultimate Scholar

Yue Lang is very clear about what it means to have four times as many mass vacancies as protons, and to carry one unit of electric charge.

This is definitely a sign of a tetraquark candidate state Zcs.

He never expected that Li Mu would discover the trace they were looking for so quickly.

Of course, maybe this is just a coincidence, because one piece of data can’t explain anything, a set of collision data, the sample size is too small, it is difficult to use it to support this important discovery, and it will not be recognized by the physics community.

But it doesn't matter, Li Mu's search has provided ideas for the follow-up.

As long as they can find more identical samples from the collision data, it will be enough to prove that this thing is the target they want to find.

Yue Lang was extremely excited.

On the same day, they bought air tickets to Beijing the next day.

As soon as the next day arrived, Yue Lang took Li Mu to Shangjing.

...

Shangjing, Institute of High Energy Physics.

As the most advanced unit of high-energy physics research in China, the Institute of High-Energy Physics can be regarded as the place where all high-energy physicists in China gather the most.

After all, only here is the particle collider for them to conduct research.

Under the leadership of Academician Yue Lang, Li Mu came here for the first time, and the discussions everywhere made him feel an academic atmosphere.

Of course, Yue Lang is an academician in the field of theoretical physics in China, and there are still quite a few people who know him here.

All of a sudden, many people greeted him.

"Hello Academician Yue!"

Yue Lang nodded to these people as a response, and then without stopping at all, he continued to lead Li Mu into the research institute.

When passing the corner, they just met a person.

The man was taken aback when he saw Yue Lang, and asked, "Hey, Lao Yue, didn't you just say that you would go back to the Shanghai stock market for two weeks? Why did you come back after only three days?"

Immediately, he turned his head and looked at Li Mu: "Wait, this is... Li Mu, Lao Yue, it seems that you are here because of Li Mu when you ask for leave?"

Yue Lang waved his hand: "Don't ask so many questions, where is Old Wang, I have something very important to find him."

"Old Wang? I should be preparing for a meeting now. I'm going to the meeting room now."

"What meeting?"

"It's not about finding the four-quark Zcs, which is the most important project of our Institute of High Energy Physics this year." The person said: "After all, the existence of the hidden and charming four-quark candidate state Zcs was only considered Various models have predicted it, as long as it can be found, it will be a shock to the entire academic world.”

"Almost all high-energy physics institutes around the world have put this project on the log."

"I heard that there are many research groups at CERN who have started to look for it."

"If we start for so long and still can't find it, and someone snatches it in the end, we will lose our lord."

Speaking of this, he also sighed: "But who knows how long it will take for us to find it, CERN has attracted half of the world's particle physicists there, and our Institute of High Energy is crying every day that there is a shortage of people, so The large amount of data makes it a headache to think about it, so it’s no wonder Lao Wang wants to get CEPC out every day.”

Hearing this old friend's complaints, Yue Lang frowned, then patted him on the shoulder with a smile and said: "Don't worry, don't worry, there must be a way for the car to reach the mountain, and the boat will be straight when it reaches the bridge. Maybe we will find it in a few days?"

The man cast a glance at Yue Lang, and said angrily, "You still have such a good attitude."

Yue Lang waved his hand: "Stop talking, let's go to the meeting room first."

Then they stopped talking nonsense, and they quickly walked to the meeting room.

On the way, Li Mu also knew the identity of this person. Jiang Yuren, an academician of theoretical physics, is also a professor of the School of Physics of Qinghua University. He is a pillar-level figure in the domestic theoretical physics circle like Yue Lang.

Moreover, Jiang Yuren and Yue Lang also belong to the same research group, and both are responsible for the search for the latently charming tetraquark candidate state Zcs containing strange quarks.

Seeing Jiang Yuren's troubles from time to time, and Yue Lang's smiling face, Li Mu shook his head amusedly. It seems that his mentor is also very good at surprising people.

...

After a while, they walked into the meeting room.

There are already many people sitting in it, basically bringing together the top high-energy physicists in China.

There are several academicians sitting in the first row alone.

And when Yue Lang walked in, many people greeted him immediately.

"Hey, Lao Yue, you're back today? Hey, this is Li Mu, right?"

"Fortunately, you came early, and there is still a seat here. Come and sit. By the way, Li Mu, come and sit here too."

All the seniors in the field of high-energy physics in China expressed their goodwill to Li Mu.

However, Yue Lang was not in a hurry, waved his hands at these people, and then led Li Mu towards a person standing on the podium.

"Old King."

The man glanced at Yue Lang and said, "What's the matter? I'm just getting annoyed right now."

This person is the director of the Institute of High Energy Physics, Wang Fang, a leading figure in high energy physics in China, and has a great reputation in high energy physics in the world.

It first proposed the "Swap Method" to solve the time-symmetrical background problem in time-asymmetrical signals, which is of great significance to low-background neutrino experiments; it was the first time to completely calculate the neutron yield and energy spectrum caused by cosmic rays, It has cleared up the confusion surrounding this issue in the world for more than 20 years, and is of great significance to low-background neutrino experiments, proton decay, double-b decay, and the search for dark matter.

Moreover, in addition to his outstanding ability in academic research, he is also an excellent particle collider designer. He participated in and led the design process of several important particle colliders in Huaguo, including the Shanghai The transformation and upgrading of the electron-positron collider and the design of the Shangjing Spectrometer III were also completed under his leadership.

In the entire particle physics community, this is definitely a big cow among the big cows.

However, this is the case, and he is also having a headache for the most important research project of the Institute of High Energy at the moment.

Where is that candidate state Zcs hidden?

Yue Lang didn't have any objection to Wang Fang's impatient attitude, because they all knew that Wang Fang's character was like this, he said with a smile: "It's a very important matter, let's go outside and talk about it, and after listening to it, you shouldn't will be annoying."

Wang Fang raised his eyebrows and couldn't help guessing: "Did you find anything?"

"Let's go out and talk." Yue Lang said, and then gave Li Mu a look.

Wang Fang showed a suspicious expression, but nodded simply: "Okay, then I'll see what you want to say."

Then the three of them walked out under the eyes of hundreds of people in the meeting room.

until five minutes later.

The three of them returned to the conference room under the eyes of hundreds of people.

It's just a little different that Director Wang, who seemed to dislike everyone recently, actually showed a shocked expression on his face, as well as a kind of disbelief.

Obviously not slowed down.

That stunned look can actually appear on the face of Director Wang?

All the people present were very curious, what did they say when they went out just now?

But at this time, Wang Fang also returned to the podium.

He stretched out his hand and rubbed his neck to bring himself back to his senses for a while.

Thinking of what Li Mu told him outside just now, he couldn't help but glance at Li Mu again.

this young man...

Of course, he had also heard of the deeds that Li Mu had done before, but he felt that Li Mu and himself had nothing to do with each other, so he didn't care too much, and he might as well put that little thought into research.

But now, he suddenly had the idea of ​​snatching Li Mu from Yue Lang.

Shaking his head with a smile, then looking at the seat below again, he said, "Okay, it's time for the meeting."

"Next, let's invite Li Mu to come on stage to share his discoveries with everyone."

Wang Fang's words made everyone in the auditorium unable to react for a while.

At the beginning of this kind of meeting, it is usually to go through the process first and summarize the recent situation, so this kind of report is usually done by Wang Fang, the director.

As a result, when Li Mu stepped onto the stage, they reacted unexpectedly.

What Wang Fang said just now seems to be... Li Mu?

Everyone: "???"

"What happened?"

On the seats under the stage, Jiang Yuren and Yue Lang sat together and saw this scene, and immediately asked Yue Lang next to him: "What did you say when you went out just now?"

Yue Lang waved his hand: "You read it before you talk."

"Brothers for so many years, are you still hiding it?" Jiang Yuren said angrily, but then quickly turned his attention to Li Mu.

He faintly felt that something big was about to happen.

And the other people around were also discussing this with puzzled expressions, and eventually they all quieted down, quietly waiting for Li Mu's report.

Li Mu stepped onto the stage, and with Wang Fang's help, turned on the multimedia.

Insert the U disk into it, and then open the PPT that was temporarily made on the plane today.

On the first page, there are two sets of data.

It is the 1145th combination of 4514 sets of data.

When everyone at the scene saw the two sets of data, they were all taken aback.

"The data of the 1145th group seems to be..."

There are still many big cows present. With their sensitivity to numbers, they all found that this set of data has a sense of sight.

As the director of the Institute of High Energy, Wang Fang squinted his eyes and said directly: "It should be the energy spectrum of the final state of charm meson decay."

"It's just that the data is not very clear."

"What are we going to do next?"

Outside just now, Li Mu only showed him the results of the analysis, but did not show him the process due to time constraints.

So he was also very curious about how Li Mu did it.

The signal of Zcs...

They have been looking for almost half a year.
