Into Unscientific

A few minutes passed.

Academician Pan handed the document back to the staff:

"Xiao Zhou, there is nothing wrong with the data, let's let the backstage do the docking."

Except for J-PARC, the data submitted by these seven institutions are relatively normal.

Although the data of clusters and the like are somewhat increased compared with the verification process of Pangu particles, they are all within the understandable category.

After all, they did not calculate dark matter themselves, and it is impossible to consume too much power to support the Academy of Sciences—the greater the power of a collider of this magnitude, the more damage it will cause.

So no one will say anything about this kind of slightly reserved situation, but Neon's practice of hiding several times the magnitude is a bit outrageous.

After getting a hint from Academician Pan.

A staff member named Xiao Zhou quickly brought the documents to the backstage and started handover with several other parties.

Although more than eight hours had passed since the opening of the press conference, the hour hand was rushing to nine hours.

But after learning that several major institutions will conduct particle inspection again, the atmosphere on the scene became much more enthusiastic.

Of course.

This also has a lot to do with the "rich experience" of the participants.

The professional environment involved in the two disciplines of mathematics and physics is very complex, so the conferences generally last for a long time.

When encountering some more humane institutions or universities, it may be divided into two sessions in the morning and afternoon, with a break of two or three hours in between.

But some organizations don't pay much attention to these things, and there are countless examples of meeting for seven, eight or even ten hours in a row-but generally it will not exceed fifteen hours.

The longest press conference in the physics world is the 2015 International Conference on High Energy Physics, which is held in Paris.

The duration is.

14 hours and 37 minutes.

From 9:00 a.m. Paris time until nearly 12:00 p.m.

So for these 'old birds'.

Long meetings are really nothing.

After all, the scene of this kind of specification conference is quite large, and you can sleep directly when you are tired. The key is to be healthy.

After receiving a reply from Academician Pan.

The programmers in the background of the press conference immediately re-established the relevant channels.

at the same time.

The headquarters of the seven organizations selected for particle collisions are also in full swing for preparations for various links at this time.

Although a lot of lead ion beams were left in the verification process of the Pangu particles before, there is no need for further production of raw materials.

But the collider, as a super-large physical experiment equipment, can't be done with just one raw material.

Calibration of superconductors, delineation of electromagnetic fields, calculation of the most efficient cross-sectional area, etc.

These are things that need to be done.

This moment.

Neon lights thousands of kilometers away.

Southern Ibaraki Prefecture.

Tsukuba City.

This is a neon city famous for the label of Research Academy City, also known as Tsukuba Science City.

Its total area is only 284.07 square kilometers, and there are no less than 50 official neon education or research institutions such as the University of Tsukuba and the Institute of Industrial Technology.

In the entire city of Tsukuba, the total number of people currently engaged in scientific research is as high as 22,000.

Among these dozens of research institutions, KEK, the research institution of Neon High Energy Accelerator, is undoubtedly the most famous one.

Founded in 1971, KEK has four large-scale facilities that are top-notch in Asia or in the world:

Pulse spallation neutron device KENS,

Asymmetric electron-positron collider KEKB,

Accelerator Test Facility ATF,

and the proton synchrotron J-PARC.

That's right, KEKB is the well-known Belle detector, which belongs to KEK-it directly contributed to the 2008 Nobel Prize in Physics for Makoto Kobayashi and Toshihide Masukawa.

As for the proton synchrotron J-PARC?

Let me introduce it with the most intuitive parameters - its energy level upper limit is 50GeV.

That's right.

50GeV.

So sometimes it needs to be admitted positively that although the little days are disgusting, their investment in scientific research is indeed worth learning.

Therefore, in the Chinese physics circle, you will often find a phenomenon:

Many people scolded the Neon people, but at the same time envied the Neon people.

The scolding is because of the feelings of the family and the country, and the envy is because their equipment is really advanced and they really dare to invest

This is why so many people miss CEPC:

That thing is expensive is really expensive, but it is also really important.

At present, the highest level of accelerator in China is only 3.5GeV, but now the front-end particle physics research is in the field of 10GeV, without sufficient level of equipment, how can it be possible to produce results?

Indeed.

To put it bluntly, particle collisions are just a matter of luck, and with equipment, you may not be able to find anything-and the probability of this situation is still very high.

But if there is no such equipment, then even the so-called "possible" does not exist.

all in all.

If Kamioka Laboratory is the brain of neon particle physics, then KEK is undoubtedly the heart of neon particle physics.

This moment.

Xiao Lincheng, who was called out from the bed by his assistant, hurried to the J-PARC accelerator control room in B3 area while wearing a coat, and found the current director of KEK, Koichiro Nishikawa, who was making related preparations:

"Xichuan-kun, how is the situation?"

Koichiro Nishikawa looked reverently at the Nobel laureate who was still working as a consultant at KEK after retirement, put his hands on both sides of his thighs, and bowed straight:

"Senior Xiaolin, the data is being imported now, and it should be almost ten minutes later."

"What about the beam tube?"

"Already in pre-launch."

"What about the gauge factor for the collision section?"

"0.000293, the minimum solid angle of the target is 1.99°."

Xiao Lincheng nodded in satisfaction:

"Yoxi."

Now 78-year-old Xiao Lincheng is in poor health. Over the years, he has been diagnosed with renal vascular-interstitial disease and pancreatic cyst, so he has been undergoing related treatment for a long time.

The reason why he stayed in Tsukuba City was because he really couldn't break away from scientific research.

The second reason is that the University of Tsukuba has a proton beam therapy center, and the current treatment level of proton beam radiation is also top-notch in the world.

not long ago.

After the calculation team started to calculate the Fermi surface data, Makoto Xiaolin went back to his room to rest because he was a little tired.

It wasn't until the experiment was about to start that he was woken up by the assistant sent by Koichiro Nishikawa.

Afterwards, Xiao Lincheng found a place to sit down, took a teacup from his assistant and took a sip.

Looking at the screen, his eyes are a little misty.

Among Neon's Nobel laureates, there are two very special ones.

The first one is Shuji Nakamura.

Of course.

The Shuji Nakamura here is not the Shuji Nakamura in "The Weak Corner Tomozaki-san", but the Neon man in reality.

Shuji Nakamura only has a master's degree and graduated from Tokushima University, where neon is relatively common. After winning the Nobel Prize, he immediately quit the neon nationality and immigrated to the opposite side of the sea, and criticized neon in various public places.

On the day Dabaobei was attacked and killed, he also reposted an emoticon of Dabaobei meeting Kennedy, which was a real traitor.

Therefore, many Neon people expressed their disapproval of this Nobel Prize winner, thinking that he is a white-eyed wolf, and some Neon hackers even hacked Wikipedia for this.

Besides Shuji Nakamura, the second special one is Makoto Kobayashi.

He is special in that

His grandfather, father, mother, and sister are all members of the Japanese Communist Party.

But maybe it's because of the influence of rebellious psychology.

Makoto Kobayashi did not become a member of the Japanese Communist Party, but showed a more right-wing tendency in politics.

So you basically don't see news about Makoto Kobayashi's participation in domestic activities, and there are few interviews and reports related to him.

There is even no autobiography or books related to him - you can even buy works by Atsuto Suzuki in China, but if you search for Makoto Kobayashi's books, you can only find a manga artist with the same name.

Be it rebellious, or really dislike Huaxia.

In short, Makoto Kobayashi's attitude towards China is not friendly.

It's just that after getting older, he is relatively not as big-mouthed as Atsuto Suzuki, and he disses a few words about Chinese physics every day when he has nothing to do. (Makoto Kobayashi has not expressed his political inclinations since he won the Nobel Prize, but his previous remarks were indeed very unfriendly, so I will continue to use them by default. At least I don’t think that a person who has been hostile to China for more than 60 years will change his attitude for no reason in his old age. .)

By the way, there is another very interesting thing.

That is, although Makoto Kobayashi is right-wing, his son has also become a member of the Japanese Communist Party. Makoto Kobayashi wanted to sever the relationship between father and son at one point.

Of course.

It is not that Nihong does not have top scholars who are friendly to China. For example, Hiroshi Amano is a very representative one, and it can only be said that the number is relatively small.

all in all.

Now it is rare to get an opportunity to dismantle the University of Science and Technology, Xiao Lincheng naturally will not choose to let it go.

After a while.

Koichiro Nishikawa walked up to him quickly, handed an execution confirmation letter in front of him, and said respectfully:

"Mr. Xiaolin, the data has been prepared."

Xiao Lincheng took a few glances at the execution confirmation letter:

"What about the academy?"

"The Academy of Sciences said that the live broadcast is ready, and we can start colliding at any time."

"What about the other institutions?"

"It's not turned on yet."

Xiao Lincheng was silent for a moment, and returned the execution confirmation letter:

"Then wait, wait for Dad to cough, wait for Fermilab to turn it on, and then we will start it."

Koichiro Nishikawa stood at attention again:

"Hay!"

Then Koichiro Nishikawa walked to the operating table with the execution confirmation letter, and started the handover with the executive staff.

Another five minutes passed.

A staff member with a Chinese character face and beard raised his right hand high:

"Mr. Nishikawa, Fermilab has started!"

See this situation.

Koichiro Nishikawa waited for another half a minute before saying:

"Then Mina-san, let's turn it on too!"

"Hay!"

after the order is issued.

The main control room began to sound one after another announcing:

"Point D1 is in place!"

"The beam tube is ready!"

"The ion beam is charging. The energy level is three zones, two zones and one zone. It has reached the baseline!"

"Collision points are being fitted in real time. 2364 theoretical scatter points have been locked"

Although each position was only less than three or four meters away from each other, these announcements were shouted hoarsely, as if Corporal Morishita had possessed a body.

By the way.

This is true - in a documentary filmed by Fuji TV for Toshihide Maskawa, there was a scene like this, which looked horrifying.

That documentary was so popular between 2008 and 2010 that Neon people were a little confused when they saw the launch of Tiangong-1:

Are Chinese people so calm when they light a fire?

Objectively speaking, this kind of practice is not about who is right and who is wrong, maybe it is some kind of difference in ideology, and each other feels a little dazed when looking at each other's actions.

Then soon.

After all instructions have been entered.

The two beams of lead ions were quickly launched towards each other, and the collision was completed at a speed close to the speed of light.

Considering the relevant properties of the 11.4514GeV particle, this time KEK also designed a very delicate link:

The beam on the left is emitted normally, and the beam on the right is emitted with a delay of 7.4 nanoseconds.

In this way.

The collision point is then slightly to the right.

In other words.

In the speed interval near the speed of light, the ion beam on the right can be regarded as a target that is far away from the bombarding particles to a certain extent—note that it is to a certain extent.

Therefore, the total energy of the system is almost equal to the energy E0 carried by the bombarding particles. At the same time, this energy can be decomposed into the energy E of the relative movement of the particles and the energy E′ of the center of mass of the two particles, that is, E0=E+E′.

Assume that there are several particles bombarding the bull's-eye per unit time and per unit area-the bull's-eye is directly regarded as a single particle.

For example, if there are 5 particles bombarding a single particle in the bullseye during the period, then record: N=5mm2s1.

N can be called flux, representing the intensity of the bombardment.

If it is represented by Nσ0(θ0, 0)Δω0Δt:

After Δt time scattering, the number of particles entering the small solid angle Δω0 in the θ0,0 direction.

Then define σ0(θ0,0) as the differential scattering cross-section, which has the dimension of area.

The previous small solid angle has been determined to be 1.99°, that is to say, only Δt is the only variable that affects the optimal value of the differential scattering cross section.

See here.

Presumably many smart students understood it for the fifth time.

That's right.

At Δt=7.4 nanoseconds, both the center-of-mass scattering cross section and the dispersed particle angle have optimal solutions.

Of course.

This optimal solution is still a probabilistic solution, and currently no one can accurately predict the trajectory of particles.

The description of the track example mentioned before is

Among the 10,000 possible tracks, KEK first ruled out 1999 impossible tracks, and then selected 3999 tracks from the remaining tracks to ensure sufficient probability.

Shhhhhh-

A large number of accelerated lead ions pass through the beam tube, and the cross-sectional area of ​​each cluster is 16×16 μm, which is thinner than a hair.

There are about 1.15×10^9 lead ions inside each cluster, and there are about 30 groups of lead ions in every two pairs of clusters that will collide strongly, erupting into a giant river crab of life.

bang bang bang—

After the collision started.

Soon lead ions completed the collision with each other.

The particles after the collision are controlled to a relatively narrow range by the magnetic confinement form, and 2300 events are formed for each collision.

Various particles are included in these instances.

Such as protons, leptons, W bosons, etc.

half an hour later.

A list of more than 1.28 million cases was brought together to the supercomputer background and quickly screened.

Makoto Kobayashi sat on the chair leisurely. He had also calculated the magnitude of this particle before, and the result was exactly the same as that of Suzuki Atsuto and others.

Coupled with the same results of several other Nobel Prize winners, Makoto Kobayashi even began to ponder the name of this particle in his heart.

The magnitude of 11.4514GeV.

Or is it called Beast Particle?

Or the Koji particle?

And just when Xiao Lincheng's thoughts diverged.

On the main console not far away, Nishikawa Koichiro's exclamation suddenly sounded:

"Nani? The information is false? That particle doesn't exist?"
