MTL - Into Unscientific-Chapter 460 Don't worry too much about the children's play
Chapter 460 Children are just playing, don't care too much
be honest.
The volume of the electronic sound is not too loud.
But it appears extremely clear in the quiet and silent first row area at this time.
At the same time, due to wearing a simultaneous translator, the Chinese introduction was quickly translated into the native language of the participants.
For example, English.
For example Russian.
Another example.
Japanese.
“.”
After hearing the names Suzuki Keihisa, Suzuki Jiro, and Suzuki Masamune, the unsuspecting Suzuki Atsuto subconsciously shut down for a few seconds.
But soon.
This blank space was filled by a surge of anger.
He turned his head with fire-breathing eyes, and looked towards the place where the voice sounded.
I saw this moment.
About three meters away from him, Xu Yun held a mobile phone in his hand—the voice was uploaded from the mobile phone.
If you look closely, you can still see part of the black and white picture being played on the screen.
Exactly at this time.
The content of the video has been played until Emperor Hirohito issued the "Edict of Armistice" on the radio:
"Wow woof woof."
See this scenario.
Atsuto Suzuki finally couldn't bear it anymore, and opened his mouth with a neon curse:
"Bageya rua"
As a result, the voice did not fall.
Academician Pan beside him took a step forward and yelled at Xu Yun with an expression even more angry than Atsuto Suzuki:
"Xiao Xu, what are you doing?"
Xu Yun seemed to have regained his senses after hearing the words, and hurriedly pressed the pause button, and quickly explained:
“.Sorry, sorry, it’s like this. It’s not a bunch of reflective monsters recently. Ahem, the media people are promoting anti-war, so I followed suit and reflected on the dangers of nuclear weapons in the history of war.”
"Before the meeting, I found a blogger's related video. Halfway through the meeting, I just locked it and locked the screen."
"Just now I was going to search for some information about the magnitude of particles, so I turned on my phone without much thought, and then the video played automatically"
Academician Pan's face at this time is still 'remaining anger', frowning to Xu Yun:
"Retrieve information? Then why don't you use the Aurora system?"
Xu Yun's face turned bitter when he heard the words, pointing to the data terminal and saying:
"Teacher, there is only one data terminal here, who will get me?"
Academician Pan turned his head to look at the data terminal, and said in silence for a moment:
"Since that's the case, don't take this as an example, please apologize to Mr. Suzuki."
After speaking, he looked at Atsuto Suzuki at the side again, with a hint of apology on his face:
"Mr. Suzuki, I'm sorry, children are ignorant, just play with them casually, please bear with me."
Atsuto Suzuki:
“.?”
Then he didn't wait for his reaction.
Xu Yun came to him quickly, with a straight body and a standard craftsmanship:
"Mr. Suzuki, Smith Marseille! Red bean paste Smith Marseille!"
The blue veins on Atsuto Suzuki's forehead twitched violently a few times, even though he was full of dissatisfaction in his heart, he didn't know how to vent it at this moment.
After a while.
Atsuto Suzuki took a deep breath, and silently recited countless words of "calm, calm, calm, calm, calm, calm, calm" in his heart, before he forced a smile:
"It's okay, Dr. Xu, it's a good thing to know how to reflect on the past, and you shouldn't be criticized."
"Using your old Chinese saying, it is an unintentional mistake."
"I hope you can continue to maintain this concept in the future. The damage caused by war to human civilization is simply unimaginable, especially nuclear war."
After listening, Xu Yun nodded with a cute face:
"Yes, the damage is too great. Look at this Suzuki Jiro, only half of his head is left."
Atsuto Suzuki:
"?????"
Seeing that Atsuto Suzuki was about to run away again, Academician Pan hurriedly dragged Xu Yun past him, and decisively changed the subject:
"Okay, the little episode that has nothing to do with the experiment is here first, let's put the focus back to the original place, and everyone can't wait."
Witten also showed his high EQ at this time, and nodded quickly:
"Yes, yes, let's talk about academic matters first, Mr. Pan, I wonder if you can accept my suggestion?"
Heard this.
Academician Pan couldn't help showing a trace of hesitation on his face—different from the anger he pretended before, he was really hesitant at this time.
According to his original idea.
It is obviously most appropriate to carry out the re-inspection of the two particles at the same time. If one is followed by the other, the Academy of Sciences will bear a certain risk.
But on the other hand.
Atsuto Suzuki, the old Baga, was a bit annoying, but he was right in saying something.
That is, it is too troublesome to verify particles of the order of 923.8GeV, and China does not have equipment for TeV-level particle collision experiments.
The most advanced institution currently in operation in China is the Modu Light Source, with a magnitude of 3.5GeV, which belongs to the light source in the middle energy area.
The collision magnitude of HKUST Synchrotron Radiation Laboratory is 800MeV, which is a thousand times worse than 923.8GeV.
Even the Yanjing Electron Positron Collider, which has stopped taking data, has a fine range of 2-5GeV.
In the early years, Huaxia planned to invest in the establishment of a circular electron-positron collider, also known as CEPC, which is of sufficient magnitude.
But CEPC was finally rejected in the 13th Five-Year Plan period, with 5 votes in favor of high-energy fields, 5 votes against non-high-energy fields, and 1 vote of government representatives against.
Although the Institute of High Energy has obtained pre-research funds and is preparing to fight for it during the 14th Five-Year Plan, it is obviously impossible to directly put it into use at today’s press conference—the parallel world is almost the same.
Except CEPC.
Yanjing also has a 6GeV high-energy light source under construction, and Luzhou also has a 2.2GeV low-energy light source under construction.
In other words.
If the data of the Academy of Sciences Group needs to be verified, it must seek help from other institutions.
But once the 11.4514GeV particle is really discovered, how many institutions are willing to help the Academy of Sciences to verify it?
Just when Academician Pan hesitated.
Xu Yun, who had just been pulled to his side by him, suddenly approached him again, and said in a low voice:
"Teacher, I have something to tell you."
Academician Pan was taken aback for a moment.
Then he quickly glanced at the camera, and after making sure that the camera did not lock him, he said to Xu Yun:
"What's up?"
"The particle of 11.4514GeV should not exist."
“.”
Academician Pan's expression didn't change much, but his left hand that was naturally drooping by his side quietly clenched:
"How to say?"
"The value of the space angle distribution group SU3 is wrong. The 4 mass eigenstates after the spin 1/2 mixture guarantee that it must be a stable particle, then its SU3 number can never be -1, and the other is."
Xu Yun knew that time was limited, so he reported several sets of numbers concisely.
Academician Pan was taken aback again.
Xu Yun's words may sound a bit rambling to outsiders, but to a bigwig like Academician Pan, they are extremely clear.
Mentioned earlier.
The reason why the Pluto particle can be discovered is because it has some influence on the Pangu particle, just like Pluto to Uranus.
That is to say, the two are related in some aspects, which was finally discovered by Witten keenly.
This association can be reflected in various values, and the spatial angle distribution group SU3 is one of them.
Pluto particles and Pangu particles must be both stable particles, and the SU3 of Pangu particles is -1, then the Pluto particles must not be this value.
This reason is actually very simple, but it’s still the same as the previous sentence—there are too many things that big bosses need to consider today, and it is impossible to fully consider every aspect.
But Xu Yun is different.
His vision has been blessed, and he can see some blind spots in his vision that are ignored by others. This is also his biggest advantage today.
Of course.
Academician Pan didn't understand Xu Yun's request to God, but he could tell whether what Xu Yun said was true or not.
Think here.
Academician Pan's heart beat faster than usual.
The reason why he is unwilling to accept Weiteng's suggestion is mainly because he is worried that if 11.4514GeV is verified first, then Atsuto Suzuki and others may use the test report to make trouble.
Let alone the existence of particles, the pressure on the Academy of Sciences will suddenly increase.
Even if the particle is not found, Atsuto Suzuki and the others may use a certain interval signal as an example to declare that the particle 'may exist'.
But if the 11.4514GeV particles are totally fake
Then the order of the Academy of Sciences groups will become more favorable.
After all, "does not exist" and "cannot find", these are two concepts.
in particle physics.
Assuming that a particle really exists, even if you can't find it for a while, there will be some signals that can be used for reference.
Such as the Higgs particle.
Before this particle was officially discovered, CERN had captured more than 30 signal wave packets, which is also one of the reasons for CREN to persist.
But if a particle is completely absent
Then don’t talk about the signal, you won’t be able to find a single bump.
At that time, Atsuto Suzuki wanted to wash the floor, but he couldn't find a suitable whitewashing point.
at the same time.
The content of the exchange between Xu Yun and Academician Pan was also transmitted to Hou Xingyuan in the background through earphones.
The experts in the background may have a gap with Academician Pan in terms of personal ability, but the strength of the team formed is not low.
So fast.
Academician Pan heard Hou Xingyuan's reply:
"Xiao Pan, agree to Wei Teng's plan."
Academician Pan tapped his ears twice calmly, indicating that he had received the news.
Then he turned his head again and said to Witten:
"No problem, Professor Witten, we accept your proposal."
Seeing this, Wei Teng felt slightly relieved.
As long as the Academy of Sciences is willing to make concessions.
Then he thought for a moment, and pointed to the big screen that was broadcast live earlier:
"Mr. Pan, I'm afraid I have to ask the Chinese Academy of Sciences to help me connect the signal and the screen."
Academician Pan nodded sharply:
"OK."
After the Academy of Sciences has made a decision, the rest is very simple.
Atsuto Suzuki, Higgs, Tufuft, and the heads of several other institutions got together and quickly decided on the list of institutions for particle detection.
A total of seven institutions were selected, namely:
The first is the Fermi National Accelerator Laboratory, abbreviated as FNAL.
Its accelerator is 1.2 miles in diameter and can accelerate protons to 980GeV.
This is currently the second highest energy collider in human history, where the discovery of the fifth quark, the bottom quark, and the sixth quark, the top quark, came from.
The second is the Stanford Accelerator Center SLAC.
Length 3.2KM, particle energy level 15GeV.
Achievements include the discovery of tau, the discovery of the fourth quark, the charm quark, and the quark structure inside the proton and neutron.
The third is the Neon High Energy Accelerator Research Institute, KEK, and the collider used is J-PARC.
means that the charge-parity of B meson is not conserved.
The fourth is the Brookhaven National Laboratory across the sea, referred to as BNL.
The discovery of the fourth type of quark, the charm quark, and related discoveries in high-energy nuclear physics all came from this. Mr. Li Zhengdao, Mr. Yang Lao and Mr. Ding Zhaozhong all worked here.
The fifth is the German Electron Synchrotron Research Institute, referred to as DESY.
The sixth is the Budeker Institute of Nuclear Physics of the Maoxiong Academy of Sciences, referred to as BINP, the absolute front-end institution of plasma physics.
The seventh is LHC, which is the Large Hadron Collider under CERN.
During the entire process of determining the list of institutions, there was an episode.
That is, Carlo Rubia, the head of CERN, has not shown up much, and Higgs came forward to negotiate in the end.
This collision still uses lead ions, that is, the same ion beam used to verify the Pangu particle, which saves a lot of preparation time.
Half an hour later.
Responses came from major institutions:
The equipment is ready.
"Academician Pan."
Then a staff member quickly came to Academician Pan and handed a document to him:
"These are the experimental parameters of the seven institutions, please have a look."
Academician Pan thanked him, took the file and read it.
As a result, he looked at it, and he couldn't help raising his brows:
"Each beam is designed with 1270 clusters, tsk tsk, J-PARC has spent a lot of money."
The staff around him also showed a hint of anger on their faces when they heard this:
"Isn't that how it was in the small days? When verifying the Pangu particle before, it was said that the maximum number of clusters can only be 300. How shameless!"
Academician Pan smiled at him, but did not answer.
Elementary particles have a very small volume at the microscopic scale, and collisions can only occur at the spatial scale of 10^1510^-16.
But in a real collider, the diameter of the vacuum tube that carries the accelerated particles is on the order of centimeters, and it is basically impossible for them to meet—it is too open.
So during the collision.
The accelerator first ‘compresses’ the particles into an ion beam, and then injects them from the secondary accelerator into the main accelerator pipeline at strict time intervals.
Each group of such particles is called a cluster.
The higher the density of clusters in a particle beam, the shorter the collision period and the more violent the reaction.
But on the other hand.
As the cluster density increases, the equipment loss and material expenditure of the accelerator will also increase.
At the same time.
Due to the difference in collision magnitude, the upper limit of the cluster density of each accelerator is also different.
For example, in reality, there is an upper limit to the firing frequency of each firearm. Exceeding this number will cause the barrel to overheat and affect the life of the firearm.
If you compare LHC to Lu Dun 2000.
Then J-PARC is at best an ordinary automatic rifle.
At present, J-PARC has increased the number of clusters to 1270. To some extent, this has overdrawn the life of J-PARC.
It can only be said that the neon side is cruel and must find the particle.
Students who were particle colliders in their previous lives should know this.
Although the particle trajectory is a probability model, after introducing the particle density model, the probability of certain 'events' can be much more accurate.
Of course.
The exact magnitude is still terrible, generally around 10 to the 23rd power.
However, this magnitude is still controllable for supercomputing, and its practical nature is
Collision point.
For example, LHC has four collision points, and the theoretical maximum bundle crossing frequency on each collision point is 40MHz.
That is to say.
Each collision point can have up to 40 million bunches of intersections per second.
Combined with the Fermi surface data calculated by other groups, in theory, at least two of the seven institutions can get accurate results.
No matter how bad it is.
is also less than 3 times the standard deviation
signs.
Note:
Hospital hanging water, 37.5 degrees, send!
The identity of the particle will be revealed soon. There is actually a foreshadowing in Chapter 216. I don’t know if anyone can find it. I suggest you go back and review it, laughing.
