What does it mean to have a mass gap of more than four times more protons, and to carry one unit of charge, Yue Lang is very clear in his heart.

This is definitely a signal for a tetraquark candidate state Zcs.

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

Of course, maybe this is just a coincidence, because one piece of data doesn't say anything, and a set of collision data, the sample size is too small to support such an important discovery, and it will not be recognized by the physics community.

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

If only they could find more of the same sample from the collision data, it would be enough to prove that this thing was the target they were looking for.

Yue Lang's heart was extremely excited.

On the same day, they bought a ticket to Beijing the next day.

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

……

Institute of High Energy Physics, Shangjing.

As the most cutting-edge unit in the study of high-energy physics 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, it's only here that there is a particle collider for them to study.

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, as an academician of the domestic theoretical physics community, there are still many people who know him here.

For a while, many people greeted him.

"Hello Academician Yue!"

Yue Lang nodded at these people, in response, and then did not stop at all, and continued to walk towards the research institute with Li Mu.

When they passed around the corner, they happened to meet a person.

这个人见到岳琅之后就是一愣，问道：“诶，老岳，你不是才说要回沪市两个周嘛，怎么这才过去没三天吧，就又回来了？ ”

Immediately, he turned his head to look at Li Mu: "Wait, this is ...... Li Mu, Lao Yue, it seems that you asked for leave to go back just for Li Mu? ”

Yue Lang waved his hand: "Don't ask so much first, where is Lao Wang, I have something very important to look for him." ”

"Lao Wang? I should be getting ready for a meeting, and I'm going to go to the conference room right now. ”

"What's the meeting?"

"It's not about finding the tetraquark Zcs, it's the most important project of the year at our Institute of High Energy Physics. This person said: "After all, the existence of the candidate state Zcs of the hidden tetraquark was only predicted by various models, and as long as it can be found, it is worth shaking for the entire academic community." ”

"Now almost all the world's high-energy physics institutes have put this project on the log."

"I've heard that there are a lot of research groups at CERN that are starting to look for them."

"If we start first and can't find it for so long, and finally get robbed by others, we will lose our adults."

Speaking of this, he also sighed: "But the devil knows how long it will take us to find it, CERN has attracted half of the world's particle physicists, and our high-energy institute is shouting every day that there is a shortage of people, such a large amount of data, it is a headache to think about it, no wonder Lao Wang wants to get CEPC out every day." ”

Listening to this old friend's complaints, Yue Lang raised his eyebrows, then patted him on the shoulder with a smile and said: "Don't worry, don't worry, there must be a road before the car reaches the mountain, and the boat will naturally go straight to the bridge, maybe we will find it in a few days?" ”

This man glanced at Yue Lang and said angrily: "You can still have such a good mentality." ”

Yue Lang waved his hand: "Don't say it, let's go to the conference room first." ”

Then, without further ado, they quickly walked towards the conference room.

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

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

Seeing Jiang Yuren's troubles from time to time at that time, as well as Yue Lang's smile on the corner of his mouth, Li Mu shook his head funny, his mentor seems to be very good at surprising people.

……

A moment later, they walked to the conference room.

There are already many people sitting in it, and basically the top high-energy physicists in the country are gathered.

There are several academicians sitting in the first row alone.

And when Yue Lang walked in, he immediately attracted many people's greetings.

"Yo, Lao Yue, are you back today? Eh, this is Li Mu, right? ”

"Fortunately, you came early, there is still a place here, come and sit, by the way, Li Mu, come and sit here."

The seniors in the domestic high-energy physics community have expressed their goodwill to Li Mu.

It's just that Yue Lang was not in a hurry, waved his hand at these people, and then led Li Mu to the person standing on the podium.

"Lao Wang."

This person glanced at Yue Lang and said, "What's the matter?" I'm struggling with it right now. ”

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

For the first time, he proposed the "Swap Method" to solve the temporal symmetric background problem in temporal asymmetric signals, which is of great significance for low-background neutrino experiments. For the first time, the neutron yield and energy spectrum induced by cosmic rays have been completely calculated, which has swept away the confusion surrounding this problem in the world for more than 20 years, and is of great significance for low-background neutrino experiments, proton decay, double-B decay, and dark matter search.

Moreover, in addition to his outstanding ability in academic research, he is also an excellent particle collider designer, and he has participated in and led the design process of several important particle colliders in China, including the transformation and upgrading of the Shangjing Positron Collider and the design of the Shangjing Spectrometer III, which was also completed under his leadership.

In the entire particle physics community, this is definitely the best of the best.

However, he is also worried about the most important research program of the Institute of High Energy at the moment.

Where is that candidate Zcs hidden?

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

王方挑了挑眉，不由猜测道：“难道你有什么发现？ ”

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

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

Then the three of them walked out under the gaze of hundreds of people in the conference room.

Until five minutes later.

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

It's just a slight difference that Director Wang, who has been looking like no one likes anyone recently, actually showed a shocked expression on his face, and there was a kind of disbelief.

Obviously, he didn't get his composure.

That stunned look could actually appear from the face of this director Wang?

For a while, everyone present was curious, what did they say when they went out just now?

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

He reached out and rubbed his neck, letting his mood come 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.

The young man ......

Before, of course, he had heard of the deeds that Li Mu had done, but he felt that Li Mu couldn't fight with himself, so he didn't care too much, so it was better to put that little thought into research.

However, now, he suddenly had the idea of snatching Li Mu from Yue Lang's hands.

Shaking his head with a smirk, then looking at the seat below again, he said, "Alright, it's meeting time." ”

"Next, let's invite Li Mu to come to the stage to share his findings with you."

Wang Fang's words made everyone in the audience not react for a while.

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

As a result, when Li Mu came to the stage, they reacted unexpectedly.

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

Everyone: "??? ”

"What's going on?"

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 just go out and say??" ”

Yue Lang waved his hand: "You can read it first." ”

"Brother for so many years, you still keep it a secret, right?" Jiang Yuren said angrily, but then hurriedly turned his gaze to Li Mu.

He had a vague feeling that something big was going to happen.

And the other people around were also talking about this with puzzled faces, and finally they all quieted down, quietly waiting for Li Mu's report.

Li Mu walked onto the stage, and then with the help of Wang Fang, he turned on the multimedia.

Plugged in the USB flash drive, and then opened the PPT that I made temporarily 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 stunned.

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

There are still a lot of big bulls present, and with their sensitivity to numbers, they all find that this set of data has a sense of immediacy.

And Wang Fang, who is the director of the Institute of High Energy, squinted his eyes and said directly: "It should be the energy spectrum of the decay end state of the meson." ”

"It's just that the data isn't clear."

"What's next?"

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

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

ZCS signal......

They've been looking for more than half a year.
