Chapter 458: Children play with each other, dont take it too seriously
be honest.
The volume of electronic music 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. All he saw was this moment.
About three meters away from him, Xu Yun suddenly held 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 to Yuyin Broadcast, where Emperor Hirohito issued the "Armistice Rescript" on the radio: "Woof woof woof woof..."
See this situation.
Atsushi Suzuki finally couldn't bear it any longer and opened his mouth with a neon curse: "Hagaya rua..."
As a result, the words were not spoken.
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 lately...ahem, the media people are promoting anti-war, so I started to reflect on the harm of nuclear weapons in the history of war."
"Before the meeting, I found a related video by a blogger. When I was halfway through watching it, the meeting just started, so I locked it directly on the screen."
"Just now I was going to search for some information about particle magnitude, so I turned on my phone without thinking too much, and then the video started playing automatically..."
Academician Pan's face at this time was still angry, 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, silent for a moment and said:
"In this case... If you don't do this 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 didn't wait for his reaction.
Xu Yun quickly came to him, his body straight and he said with a standard craftsman spirit: "Mr. Suzuki, Smith Marseille! Red bean paste Smith Marseille!"
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.
"It's okay, Dr. Xu. It's a good thing to know how to reflect on the past, and you shouldn't be criticized harshly." "In your old Chinese saying, it was an unintentional mistake."
"I hope you will continue to maintain this concept in the future. The harm caused by 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 stopped him
Pulling Xu Yun away, he decisively changed the topic:
"Okay, that's it for the little excerpts that have nothing to do with the experiment. Let's get the focus back to where it started. Everyone can't wait."
Witten also showed his high emotional intelligence at this time and quickly nodded:
"Yes, yes, let's talk about academic matters first, Mr. Pan, I wonder if you can accept my suggestion?" Hearing these words.
A trace 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 800MeV, which is a thousand times worse than 923.8GeV.
Even for the Yanjing Electron Positron Collider, which has stopped taking data, the precision range is 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 vote against.
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 are willing to help the Academy of Sciences verify it? Just when Academician Pan was hesitant.
This chapter is not over yet, please click on the next page to continue reading! 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 focused on him, he asked Xu Yun: "What's the matter?"
"The 11.4514GeV particle...should not exist."...
Academician Pan's expression did not change much, but his left hand, which was naturally hanging by his side, quietly clenched: "How do you say it?"
"The numerical 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 is...
"
Knowing that time was limited, Xu Yun reported several sets of figures concisely and concisely. Academician Pan was once again stunned.
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 particle, just like Pluto did on Uranus.
That is to say, the two are related in some aspects, which was finally discovered keenly 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 the same sentence as before - there are too many things that the big guys 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 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. Thinking of this.
The beating speed of Academician Pan's heart couldn't help but speed up a bit.
The main reason why he was unwilling to accept Witten's suggestion was that if 11.4514GeV was verified first, Suzuki Atsushi and others might be able to use the test report to cause trouble.
Let alone saying that the particles really exist, the pressure on the Academy will suddenly increase.
And even if the particle is not found, Suzuki Atsushi and others may use a certain interval signal to explain the problem, thereby claiming that the particle 'may exist'.
But if the 11.4514GeV particles are completely fake...
Then the order of ranking by the Academy of Sciences will actually 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, which is also one of the reasons for CREN to persist.
But if a particle does not exist at all...
Let alone the signal, you won't be able to find the slightest bump. At that time, Suzuki Atsushi wanted to wash the floor, but he couldn't find a suitable whitewashing spot. 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 very fast.
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 and said to Witten:
"No problem, Professor Witten, we accept your plan." Seeing this, Witten 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.
Atsushi 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, and the discovery of the fifth quark, the bottom quark, and the sixth quark, the top quark, came from here.
The second one is the Stanford Accelerator Center SLAC. The length is 3.2KM and the particle energy level is 15GeV.
It led to the discovery of neutrons, the discovery of the fourth quark, the charm 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. Li Zhengdao, Mr. Yang Lao and Mr. Ding Zhaozhong all worked here.
The fifth one is the German Electron Synchrotron Institute, or DESY for short.
The sixth one is Budek Academy of Bear Science
The Institute of Nuclear Physics, referred to as BINP, is the current absolute front-end institution for plasma physics.
The seventh one is the LHC, which is the Large Hadron Collider under CERN. There was also an episode in the entire process of determining the list of institutions.
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.
This chapter is not over yet, please click on the next page to continue reading! In half an hour.
Replies came from major institutions: the equipment has been prepared. "Academician Pan."
Then a staff member quickly came to Academician Pan and handed him a document: "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 hint of anger on their faces:
"Isn't that what happened in my childhood? When I verified Pangu particles before, 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 collisions can only occur at the spatial scale of 10＾-15~10＾-16.
But in a real collider, the diameter of the vacuum tube carrying accelerated particles is on the order of centimeters, making it basically impossible for them to meet - it is too open.
So during the collision?
The accelerator must first 'compress' the particles into ion beams, and then inject 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 of the accelerator and the material expenditure will 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 the 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 very determined and must find those particles.
Those who worked at a particle collider in their previous lives should all 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 accurate.
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 property is...the collision point.
For example, the LHC has four collision points, and the theoretical highest 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 matter what happens...
Also below 3 times standard deviation....signs.
Note:
Hospitalized with water, 37.5 degrees, send!
The identity of the particle is about to be revealed. 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, lol.
