Chapter 460: Children play with each other, don’t take it too seriously
Tell the truth.
The electronic sound volume is not too loud.
But it appeared extremely clear in the silent first row area.
At the same time, due to wearing simultaneous translators, this Chinese introduction was quickly translated into the native languages of the participants.
For example English.
For example, Russian.
Another example.
Japanese.
"."
After hearing the names Suzuki Keihisa, Suzuki Jiro, and Suzuki Masaki, the unsuspecting Atsushi Suzuki's mind subconsciously shut down for a few seconds.
But soon.
This blank space was filled with a surge of anger.
He turned his head with blazing eyes and looked at the place where the sound came from.
I only see this moment.
About three meters away from him, Xu Yun was holding a mobile phone in his hand - the sound was uploaded from the mobile phone.
If you look carefully, you can still see part of the black and white picture being played on the screen.
Just at this time.
The content of the video has been played on the Yuyin Broadcasting Station where Emperor Hirohito issued the "Armistice Rescript" on the radio:
"Woof woof woof woof."
See this situation.
Suzuki Atsushi finally couldn't bear it any longer and opened his mouth with a neon curse:
"Baqiya rua"
As a result, the words remained unfinished.
Academician Pan next to him took a step forward and yelled at Xu Yun. His expression even looked angrier than Atsushi Suzuki:
"Xiao Xu, what are you doing?"
Xu Yun seemed to have come to his senses just after hearing this. He hurriedly pressed the pause button and explained quickly:
".I'm sorry, I'm sorry, it's like this. I haven't been a bunch of reflection monsters recently. Ahem, the media people are promoting anti-war, so I followed it and reflected on the harm of nuclear weapons in the history of war."
"Before the meeting, I found a related video by a blogger. Halfway through, the meeting just started, so I locked it directly on the screen."
"Just now I was going to search for some information about particle magnitudes, so I turned on my phone without thinking too much, and then the video started playing automatically"
Academician Pan's expression at this time was still 'furious', and he frowned and said to Xu Yun:
"Retrieve information? Then why don't you use the Aurora system?"
Xu Yun's expression turned bitter upon hearing this, and he pointed at the data terminal and said:
"Teacher, there is only one data terminal here, who will get me?"
Academician Pan turned his head and looked at the data terminal, remained silent for a moment and said:
"In this case, if this is not the case next time, please apologize to Mr. Suzuki."
After saying that, he looked at Atsushi Suzuki aside, with a hint of apology on his face:
"Mr. Suzuki, I'm sorry, the child is ignorant and just plays with it. Please be more considerate."
Atsushi Suzuki:
".?"
Then he didn't wait for his reaction.
Xu Yun quickly came to him, his body straight and showing a standard craftsman spirit:
"Mr. Suzuki, Smith Masai! Red bean paste Smith Masai!"
The veins on Suzuki Atsushi's forehead twitched violently several times. Even though he was filled with dissatisfaction, he didn't know how to vent it at this time.
After a while.
Suzuki Suzuki took a deep breath, and thought about countless calmness and calmness in his heart, and then barely pulled out a smile:
"It doesn't matter, Dr. Xu, it is a good thing to know how to reflect on the past and should not be criticized harshly."
"To use your old Chinese saying, it was an unintentional mistake."
"I hope you can continue to maintain this concept in the future. The harm of war to human civilization is simply unimaginable, especially nuclear war."
After hearing this, Xu Yun nodded with a cute look on his face:
"Yes, the damage is too great. Look at this Suzuki Jiro, only half of his head is left."
Atsushi Suzuki:
"????"
Seeing that Suzuki Atsushi was about to go berserk again, Academician Pan quickly grabbed Xu Yun and decisively changed the topic:
"Okay, that's it for the little excerpts that have nothing to do with the experiment. Let's put the focus back to where it started. Everyone can't wait."
Witten also showed his high emotional intelligence 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?"
Hear these words.
A hint of hesitation appeared on Academician Pan's face - unlike the anger he had pretended to do before, he was really hesitant at this time.
According to his original idea.
It is obviously most appropriate to retest the two particles at the same time. If they are done one after the other, the Academy will bear certain risks.
But on the other hand.
Although Suzuki Atsushi is a bit annoying, there is something he said that was not wrong.
That is, it is too troublesome to verify particles of the magnitude of 923.8 GeV. At the same time, China does not have the equipment to conduct TeV-level particle collision experiments.
The most advanced institution currently operating in China is the Magic City Light Source, which has a magnitude of 3.5GeV and is a medium-energy region light source.
The collision magnitude of the HKUST Synchrotron Radiation Laboratory is 800 MeV, which is a thousand times worse than 923.8 GeV.
Even the Yanjing Electron Positron Collider, which has stopped taking data, has a fine range of only 2-5GeV.
In the early years, China had planned to invest in building a circular electron-positron collider, also known as CEPC, which was of sufficient magnitude.
However, CEPC was ultimately rejected during the 13th Five-Year Plan period, with 5 high-energy votes in favor, 5 non-high-energy sector votes against, and 1 government representative opposed.
Although the Institute of High Energy has currently received pre-research funds and is preparing to fight for it during the 14th Five-Year Plan, it is obviously impossible to put it into use directly at today's press conference - the parallel world is still about the same.
Except CEPC.
There is also a 6GeV high-energy light source under construction in Yanjing, and a 2.2GeV low-energy area light source is under construction in Luzhou.
In other words.
If the data from the Academy of Sciences group needs to be verified, help from other institutions must be sought.
But once the 11.4514GeV particle is really discovered, how many institutions will be willing to help the Academy of Sciences verify it?
Just when Academician Pan was hesitant.
Xu Yun, who had just been pulled to his side, suddenly came closer to him and whispered:
"Teacher, I have something to tell you."
Academician Pan was suddenly startled.
Then his eyes quickly glanced at the camera, and after making sure that the camera was not locked on him, he said to Xu Yun:
"What happened?"
"That particle of 11.4514GeV should not exist."
"."
Academician Pan's expression did not change much, but his left hand, which was naturally hanging by his side, was quietly clenched:
"How to say?"
"The value of the spatial angular distribution group SU3 is wrong. The four mass eigenstates after spin 1/2 mixing ensure that it must be a stable particle, so its SU3 number cannot be -1, and the other thing is."
Xu Yun knew that time was limited, so he reported several sets of numbers concisely and concisely.
Academician Pan was stunned again.
Xu Yun's words may sound a bit confusing to outsiders, but to a big boss like Academician Pan, they seem extremely clear.
Mentioned earlier.
The Pluto particle was discovered because it had some influence on the Pangea particles, just like Pluto did on Uranus.
That is to say, the two are related in some aspects, which was finally keenly discovered by Witten.
This correlation can be reflected in various numerical values, and spatial angular distribution group SU3 is one of them.
Pluto particles and Pangea particles must be stable particles. The SU3 of Pangea particles is -1, so Pluto particles must not have this value.
This truth is actually very simple, but it’s still what I said before – there are too many things that the big guys need to consider today, and it is impossible to completely consider every aspect.
But Xu Yun is different.
His vision has been enhanced, and he can see some blind areas of 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 false.
Think of this.
The beating speed of Academician Pan's heart couldn't help but speed up a bit.
The main reason why he is unwilling to accept Witten's suggestion is that if 11.4514GeV is verified first, Suzuki Atsushi and others may be able to use the test report to cause trouble.
Let alone saying that the particles really exist, the pressure on the Academy of Sciences will suddenly increase.
And even if the particle is not found, Suzuki Atsushi and others may use a certain interval signal to claim that the particle "may exist".
But if the 11.4514GeV particles are completely false
Then the order of the Academy of Sciences group will become more advantageous.
After all, "does not exist" and "cannot be found" are two different concepts.
in particle physics.
Assuming that a particle really exists, then even if you can't find it for a while, there will more or less be some signals that can be used for reference.
For example, the Higgs particle.
Before this particle was officially discovered, CERN had captured more than 30 signal wave packets. It is also one of the reasons for CREN to persist.
But if a particle does not exist at all
So don't talk about signals, you won't be able to find the slightest bump.
At that time, Atsushi Suzuki wanted to wash the floor, but he couldn't find a suitable spot to wash it.
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 ear return.
The back-end experts may differ from Academician Pan in terms of personal ability, but the strength of the team they form is no less than higher.
So it's quick.
Academician Pan heard Hou Xingyuan's reply:
"Xiao Pan, agree to Witten's plan."
Academician Pan quietly tapped his ear twice to indicate that he had received the message.
Then he turned his head again and said to Witten:
"No problem, Professor Witten, we accept your plan."
When Wei Teng saw this, he felt relieved.
As long as the Academy is willing to make concessions.
Then he thought for a moment and pointed to the big screen where the previous live broadcast was:
"Mr. Pan, I'm afraid I have to ask the Chinese Academy of Sciences for help to connect the signal and the screen."
Academician Pan nodded cheerfully:
"OK."
After the Academy of Sciences made its decision, the rest was simple.
Atsuto Suzuki, Higgs, Tefft, and several other agency heads came together and quickly decided on a list of agencies that would conduct particle detection.
A total of seven institutions were selected, namely:
The first is Fermi National Accelerator Laboratory, abbreviated as FNAL.
Its accelerator is 1.2 miles in diameter and can accelerate protons to 980 GeV.
This is the second-highest energy collider in human history. The fifth quark, bottom quark, and the sixth quark, top quark, were discovered here.
The second one is the Stanford Accelerator Center SLAC.
The length is 3.2KM and the particle energy level is 15GeV.
Achievements include the discovery of the tau particle, the discovery of the charm quark, the fourth type of quark, and the quark structure inside protons and neutrons.
The third company is the Neon High Energy Accelerator Research Institute, KEK, and the collision equipment used is J-PARC.
The representative result is the charge-parity non-conservation of B mesons.
The fourth one is Brookhaven National Laboratory, referred to as BNL, across the sea.
The discovery of the fourth type of quark, the charm quark, and related discoveries in high-energy nuclear physics all came from here. Mr. Li Zhengdao, Yang Lao and Ding Zhaozhong all worked here.
The fifth one is the German Electron Synchrotron Institute, or DESY for short.
The sixth one is the Budeker Institute of Nuclear Physics of the Mao Xiong Academy of Sciences, or BINP, which is currently the absolute front-end institution for plasma physics.
The seventh one is the LHC, the Large Hadron Collider under CERN.
In the entire process of determining the list of institutions, there was an episode.
That is because Carlo Rubbia, the head of CERN, has never shown up much, and in the end it was Higgs who came forward to negotiate.
This collision still used lead ions, which is the same ion beam used to verify the Pangu particle, saving a lot of preparation time.
Half an hour later.
Replies 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 seven institutions, please take a look."
Academician Pan thanked him, took the document and read it.
As he looked at it, he couldn't help but raise his eyebrows:
"Each beam is designed to have 1,270 clusters. Gee, J-PARC has spent a lot of money on this."
Hearing this, the staff around him also showed a trace of anger:
"Isn't that what happened in my childhood? When I was verifying Pangu particles, I was told that the maximum number of clusters could only be 300. How shameless!"
Academician Pan smiled at him and did not answer.
The volume of elementary particles at the microscopic scale is very small, and they can only collide at a spatial scale of 10^1510^-16.
But in a real collider, the diameter of the vacuum tube carrying the accelerated particles is on the order of centimeters, making it basically impossible for them to meet - it is too empty.
So during the collision.
The accelerator first 'compresses' the particles into an ion beam, which is then injected 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 period of collision 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 different collision magnitudes, the upper limit of cluster density for each accelerator is also different.
For example, in reality, the firing frequency of each firearm has an upper limit. Exceeding this number will cause the barrel to overheat and affect the life of the firearm.
If the LHC is compared to Landlubber 2000.
Then J-PARC is at most an ordinary automatic rifle.
Currently, J-PARC has increased the number of clusters to 1,270. To a certain extent, this is already overdrawing the lifespan of J-PARC.
It can only be said that Neon is ruthless and must find those particles.
Anyone who worked as a particle collider in their previous life should know this.
Although the particle trajectory is a probability model, after the particle density model is introduced, the probability of certain 'events' can be much more precise.
Of course.
The precise magnitude is still terrible, usually around 10 to the 23rd power.
However, this magnitude is still controllable for supercomputing, and its practical properties are
Collision point.
For example, the LHC has four collision points, and the theoretical maximum beam crossing frequency at each collision point is 40MHz.
That is to say.
Each collision point can have up to 40 million beam crossings per second.
Combined with the Fermi surface data calculated by other groups, theoretically, at least two of the seven institutions can obtain accurate results.
No better.
It is also less than 3 times the standard deviation
sign. (End of chapter)
