"When everyone sees the 1145th set of data, they will probably feel a little familiar."
"It's actually very simple. This set of data represents the final state of charm meson decay."
"But due to the interference of experimental errors, this set of data is somewhat unclear."
"So now we need to do a little bit of processing on it, which is noise reduction, to make it visible."
"Then without further ado, let's get started now."
Then, Li Mu began to demonstrate how he performed noise reduction.
But everyone present had the same expression as Yue Lang's yesterday afternoon.
Denoise the results? !
Is this really something you can do when you just start studying particle physics?
Everyone present was surprised by Li Mu's act of unleashing a big move right out of the gate.
When performing noise reduction from results, the most taboo thing is affecting the real data.
After all, the result they obtained is a combination of real data and noise data. The two are mixed together. It is difficult even to think about processing them. Generally, they can only combine the two through reverse derivation. Separate it slightly, and then remove the noisy data.
The technical difficulty——
Most people here didn't want to try it anyway.
Especially those ordinary researchers, associate researchers, etc. sitting in the back row, for a while, they had no other expression except opening their mouths.
If you are good at math, you can really do whatever you want.
Basically, only Yue Lang, whom he had seen yesterday, could maintain a normal state of mind.
Even Director Wang Fang on the side couldn't help but move his brows, and said with some surprise: "So that's how it is..."
If the noise reduction method is used to make the data clearer, it will indeed allow them to discover more information.
So, what kind of information would it be?
After just a few moments, Li Mu derived his noise reduction model.
Of course, it's just a matter of recreating the model in my mind, and it doesn't take much effort.
But for those present, this noise reduction model made them all shine.
"This noise reduction model... I dare say that even if it were taken to CERN, they would be jealous to death!"
Jiang Yuren stared at the model written by Li Mu and couldn't help but say.
"Lao Yue..."
As a result, before he could finish speaking, Yue Lang stretched out a hand to block his mouth.
"Let's see first, and then we'll talk about it later."
Jiang Yuren came back to his senses and immediately turned his head to Li Mu, and immediately fell into deep thought.
Because Li Mu has already optimized the first set of data.
This first set of optimized data finally made so many people present realize something.
However, Li Mu didn't waste any time and carried out all the next steps neatly.
"By substituting the first set of data into this noise reduction model, we can clearly determine that this set of collision data occurred at a center-of-mass system energy of 4.68 GeV."
"At this point we can clearly see that there is a great correlation between this set of data and the 4514th set of data."
"After simple analysis, there must be a particle signal with a mass of 3.98 billion electron volts!"
"Next, we will continue to analyze the reaction process of e+e-→K+ (DD*0+D*-D0)."
Immediately, Li Mu began to deduce. What is shown here is the physical reaction during the collision of electrons and positrons.
The positrons and negative electrons collided at huge speeds to reveal the truth of microphysics——
"There must be an enhanced structure within the quality threshold range of DD*0 and D*-D0!"
"Obviously, this enhanced structure cannot be explained by any known traditional charmed meson excited state, but it can be described by introducing a new Zcs (3985) exotic state."
"So I thought-"
"Without considering the existence of experimental errors, the unknown particle signal shown in this set of collision data must be the candidate candidate state of the cryptocharm tetraquark Zcs containing strange quarks that we are looking for."
Li Mu said the result as if it were a declaration.
There was silence in the conference room.
Everyone who had just been shocked by Li Mu's noise reduction mathematical skills was interrupted by this sudden conclusion at this moment.
The clue they've been looking for for so long?
Was it finally found today?
But this is not over yet.
Li Mu then said: "In addition, according to the trajectory inference, if behind this signal is indeed the Zcs (3985) we are looking for, this particle must have a charge."
"According to the analysis of the standard model theory, this Zcs (3985) + must also have another neutral adjoint state Zcs (3985) 0."
"So, if there is no problem with my derivation, then we should focus on finding more data on the final state of charm meson decay containing strange quarks to help us use more samples to confirm Zcs (3985) +, and look for its neutral accompanying state.”
"The above is what I want to share with you today."
"Sorry for disturbing everyone's normal meeting."
No one cares about what Li Mu said next.
In the conference room, there was still silence.
An amazing mathematical technique, a shocking analytical result, and a cutting-edge physics prediction.
After such a combination of punches, they were all a little confused.
But in the end, someone reacted.
Several academicians sitting in the first row stared with wide eyes as they looked at the analysis results Li Mu wrote on the blackboard.
"Zcs (3985)... indeed. "
"The enhanced structure that exists within the mass threshold range of DD*0 and D*-D0... is completely consistent with this set of experimental data! We have been looking for so long before, but we haven't found it yet? In this 4514th set of data, no one Have you seen it?"
"Even if you see it, you have to connect it with the 1145th set of data first. And if you want to connect with the 1145th set of data, you have to first reduce the noise of the 1145th set of data like Li Mu did. It's not that easy to say. ah?"
"If that's the case, have we really found it?"
"Could we have found this? Li Mu found this..."
"makes sense……"
The silence was finally broken, and these scholars couldn't help but start talking.
Until a moment later.
"Crack! Crack! Crack!"
A burst of powerful applause rang out, and everyone present looked towards the place where the applause came from.
This is exactly what Wang Fang is good at.
Everyone reacted immediately. With such a sophisticated analysis and shocking conclusion, why were they still stunned?
Suddenly, there was thunderous applause.
No one is not surprised, and no one is not amazed.
In the world of particle physics, amazing discoveries often come from such accidental discoveries.
But even if you want to discover it, you need enough skills and abilities.
Just like the process Li Mu is showing them now.
Maybe each of them has seen these two sets of data before. After all, everyone has a copy of these data, but now only Li Mu has managed to find the connection between these two sets of data and analyze the results.
Wang Fang walked onto the stage again with warm applause.
His previous expression, which looked like everyone owed him 8 million, now also showed a smile.
"Wonderful, so wonderful!"
"Just now outside, I just heard your result, but now I really see your analysis process, I realize how rare this result is."
"Now I begin to believe that there really are all-around geniuses in this world."
Li Mu smiled modestly and said: "I discovered it only by chance. With so many researchers at the Institute of High Energy, I believe that this result will be discovered sooner or later."
Wang Fang smiled: "Maybe, but time determines everything. You have done us a big favor."
Patting Li Mu on the shoulder, he then turned to look at the audience and announced: "This is the entire content of our meeting today."
"I don't think I need to say more about the subsequent schedule. Everyone should know that we will continue to count all the collision data and find more process data on the final state of decay of charm mesons containing strange quarks, and then follow Li Mu's instructions. Provide ideas and analyze them.”
"We want to find more Zcs(3985)+."
"The meeting is over!"
