Chapter 171 Restarting the Collision Experiment

On October 10, when the workers who had spent the National Day holiday returned to work, Xu Chuan, who was thousands of miles away, also welcomed the restart of the LHC Large Intense Particle Collider.

The ten-day overhaul and maintenance was finally completed and entered the final preparation stage.

Countless physicists gathered at CERN, waiting for this experiment.

On the one hand, everyone is waiting to see whether the latest collision data can correctly verify the "ideal search decay channel for the Higgs and the third-generation heavy quark Yukawa coupling" calculated by Xu Chuan.

If it succeeds, it will be a major change for CERN, or for the entire high-energy physics community.

It is so cool to perfectly integrate mathematics into physics and control the information of particle collisions with mathematics.

For the high-energy physics community, if this method succeeds, it will be worth promoting.

Any laboratory will do it if it spends some brainpower to save millions or even tens of millions of collision research funds for the collider.

Just like the first person to eat crabs, although it may be difficult, as long as someone does it first, it is always much easier for the latecomers.

On the other hand, the data generated by high-energy particle collision experiments that explore certain particles or object phenomena are not necessarily all about the target particles or target phenomena.

In the random collision of particle beams, there will always be some strange or new things that have never been discovered.

Although most of the new discoveries are useless, this cannot resist the curiosity of physicists about the new world.

Especially now that the last piece of the standard model has been completed, the physicists are more eager to discover things beyond the standard model.

Whether the data generated by the collision experiment is useful or beyond the standard model needs to be determined after discussion by physicists.

It can even be said that for CERN researchers and physicists from various countries, the second aspect is more attractive.

If a new discovery is confirmed to have great value, it may even change CERN's established research plan and become the next research target of the Large Hadron Collider.

Like the Higgs particle, it has always been one of CERN's main research goals in the 21st century.

Not only to complete the standard model, but also to explore and discover things like the origin of mass, the Higgs field, dark matter and dark energy.

The Large Hadron Collider (LHC) has entered the final preparation stage. The Swiss and French troops stationed at CERN are very skilled in persuading tourists or environmental protection organizations who come to "tour" to leave.

Then they pull out the "talents" who sneaked into CERN from nowhere or even into the underground collider track.

There is no way, because the previous head of CERN was a "cute".

In 2007, when the LHC had not been upgraded, the head of the European Atomic Energy Laboratory was not the current Professor David Gross, but another cute kid who liked to joke.

He once proudly boasted at a public press conference that the LHC had created a micro black hole.

Although he later explained that this micro black hole can only exist in the collision channel for less than 0.000001 seconds after it appears, and it does not cause any harm to the earth, it still made a big news at the time.

There were many media reporters present at the time. This should have been a boast of the powerful performance of the LHC equipment, but it was finally distorted into various versions of news by these unscrupulous media.

News like "CERN creates black holes, the earth is about to be swallowed up, and humanity is about to be destroyed" and "The Large Hadron Collider is creating black holes, which may grow and swallow up the earth." were all over the Internet and various newspapers at the time.

This immediately caused panic among ordinary people in Europe who "did not read much."

In addition, some people who were bored collected some earthquakes and floods that occurred around the world when the LHC was started.

After comparing the time, Western people became more and more convinced that the LHC would destroy the earth and cause the destruction of mankind.

Then they began to march and protest in the streets.

Some people who were not afraid of death would even try every means to sneak into the underground of CERN to destroy the Large Hadron Collider.

This phenomenon, let alone now, will still exist in CERN even in another ten years.

Therefore, Switzerland and France later arranged troops to be stationed here, and before each experiment was started, they would clear the area first.

In order to prevent any idiots from sneaking into the underground collider.

Not to mention destroying the Large Hadron Collider, even being hit by the running accelerator is a big deal.

Not everyone is Anatoly Bugorsky, who survived to old age after being hit by a high-energy particle beam in a particle accelerator.

Normally, if a high-energy particle beam flying at almost high speed in the Large Intense Particle Collider hits a particle, the grave will be covered with grass next month.

If such an accident occurs in the LHC, it will probably be shut down by protests, or at least for a period of time.

Even if it is not CERN's responsibility, there are warning signs around the Large Intense Particle Collider.

Of course, this unexpected black hole accident did not bring all bad news to CERN.

Ordinary people may be panicked by the fact that a collider can create a black hole, but it is different for the country.

Part of the reason for the subsequent upgrade of LHC comes from this.

After all, black holes have great appeal to the country.

At 9:30 in the morning, the collision experiment of the Yukawa coupling phenomenon between Higgs and the third-generation heavy quarks started on time.

Huge currents flowed into the Large Intense Particle Collider from the lines. Superconducting magnets that are ultra-low temperature frozen by liquid nitrogen and helium generate a circular strong magnetic field, and then use the electric field to accelerate charged particles.

The accelerated charged particles will be affected by the Lorentz force when moving in the magnetic field. The Lorentz force makes the charged particles move in a circle, thereby achieving repeated acceleration to approach the speed of light.

This is the principle of operation of the collider.

However, microscopic particles are also limited by the relativistic effect, and their speed can only approach the speed of light, but cannot reach the speed of light.

Moreover, as the speed increases, the relativistic mass of the particles increases, and the mass-to-charge ratio becomes larger, making acceleration more and more difficult.

In addition, this principle determines that only charged particles can be accelerated in the collider, such as electrons, positrons, protons and antiprotons, etc.

Only things that can be affected by a strong circular magnetic field can be used for collision experiments.

This is actually somewhat similar to controlled nuclear fusion technology.

Controlled nuclear fusion actually uses super-strong magnetic fields or similar technologies to control the ultra-high temperature plasma in the reactor and then generate electricity.

Of course, this is just from a basic point of view. In terms of actual details, the gap between the two is still quite large.

Two beams of high-energy light carrying more than a trillion electron volts continue to move forward, accelerate, and collide at the intersection in a 27-kilometer-long acceleration pipeline, producing fierce and shining light.

These lights are captured by detectors deployed at the intersection, and then evolved into data and energy spectrum images.

With the operation of the LHC, a large amount of collision experiment data appears every minute and every second.

Xu Chuan is still very interested in the first collision experiment that can be regarded as the leader after his rebirth.

He followed the CERN team members and stood in the front-line laboratory. Standing beside him were three leading academicians from Nanjing University, Huazhong University of Science and Technology, and Jiaotong University.

This is the first line of receiving particle collider collision data. Any data captured by the detector will be presented on the display screen here.

If you are familiar with the high-energy field and mathematical analysis, these initial data are enough for you to notice something.

In this regard, Xu Chuan will not be modest.

Not to mention the first or second in the world, at least in the top five.

After all, he discovered so many things through this collider under his feet in his previous life.

Axion particles, dark matter, dark energy, inert neutrinos, etc. In the next ten years, he relied on these discoveries and corresponding theories to be hailed as the first person in contemporary physics.

Even if you look at the entire modern history, the only three big guys who can rank ahead of him are Newton, Einstein and Maxwell.

Newton opened a new era of physics with classical mechanics, the era of classical physics.

Einstein used relativity as a major pillar of modern physics and opened a new era of modern science and technology.

And Maxwell opened the information age with classical electromagnetism.

As for him, he overturned the traditional rules of physics based on the theory of dark matter, dark energy and gravitons, and rewrote people's understanding and definition of matter.

Although he did not have time to continue his research after that, and even before he could study how to capture and use dark matter and dark energy, he was sent back to his hometown.

But the achievements he created are still dazzling to the whole world.

On the display screen of the front-line laboratory, the data generated by the particle collider under his feet depicted signal points one by one.

Xu Chuan stared at the screen with interest, staring at the familiar data on it.

If it was in the previous life, he might still be confused in the large amount of signal data.

After all, these data are only initial data, which have only been processed initially, dense, tedious and repetitive.

But after rebirth, I don't know if it is related to his major in mathematics in this life, his sensitivity to mathematics has increased a lot.

This is indeed an unexpected surprise.

Because whether it is mathematical research, physical research, or material research, it requires a high level of mathematical ability as a foundation.

Of course, it is almost impossible to rely on this sensitivity to find the data of the Yukawa coupling phenomenon of Higgs and the third-generation heavy quarks from the front-line laboratory.

After all, these data have not been processed by supercomputers, and they contain various impurities and useless data.

Xu Chuan also understood this, so he stopped paying attention after looking at it for a while.

The collision experiment was restarted in October, and the experiment on the Yukawa coupling phenomenon of Higgs and the third-generation heavy quarks lasted for two full days.

In these two days, the collider generated trillions of data, and most of these data will be discarded after being screened by the supercomputer.

The remaining part will be sorted again and sent to the database for physics experts to apply for use.

For this experiment, the first batch of applicants for collision data are naturally three universities in China.

This is already scheduled.

After all, the most ideal search decay channel for the Yukawa coupling of Higgs and the third-generation heavy quarks was calculated by Xu Chuan, and he has certain rights of suggestion and handling.

However, in addition to the three universities in China, other universities and laboratories have also applied for collision data and have been approved.

This may make people feel a little biased, but it is a very normal thing at CERN.

If the most ideal search decay channel for the Yukawa coupling between Higgs and the third generation of heavy quarks is studied this time, it is American scholars or European scholars.

When they obtain the right to use the first batch of data, China can also apply for the first batch of experimental data for processing.

Of course, whether it can be grabbed is not certain.

After all, CERN has so many physicists, and everyone will apply for projects of interest. After the application, CERN will allocate according to your contribution and previous research.

In addition, the data calculated by two or three different research institutions can be used to verify each other to ensure the correctness of the data.

Although the first group that submits the acceptance report and is approved will always obtain the right to sign, it is so realistic and cruel at CERN.

At the end of the experiment, the collision data processed by the supercomputer was sent to the group that applied for the experimental data.

In addition to Nanjing University, Huazhong University of Science and Technology, and Jiaotong University, the personnel of the Fermi National Accelerator Laboratory in the United States and the German Electron Synchrotron Accelerator Institute also applied for the collision data this time.

After all, with Xu Chuan's theoretical calculation data, the probability of discovering the Yukawa coupling phenomenon between the Higgs and the third-generation heavy quarks is very high, and there is no reason not to come in and share a piece of the pie.

If the three groups are calculated according to their strength, the Fermi National Accelerator Laboratory in the United States ranks first, the German Electron Synchrotron Accelerator Institute ranks second, and the three universities in China rank third.

However, relatively speaking, Nanjing University has the experience of analyzing the Yukawa coupling collision data between the Higgs and the third-generation heavy quarks. In addition, Xu Chuan is also the author of the theoretical calculation data, which can be said to be destined to be the other two laboratories and institutes.

After the data was distributed, the scientific research team formed by the three domestic universities immediately started work.

Three academicians + one Fields Medal candidate + several CERN researchers are a super luxurious lineup, plus there are always doctoral students, postdoctoral fellows, and even university professors as backup energy, which is destined to make the experimental data analysis data fly.

Working overtime, in just less than a week, the complete Daritz diagram was drawn.

After the Daritz diagram was drawn and checked and confirmed, Xu Chuan and the three academicians did not even have time to celebrate, and immediately submitted an application for the acceptance report meeting to CERN.

Although I know that the other two laboratories cannot produce results so quickly, I am still worried.

After all, if other laboratories grab the results of this time, it will be a pitfall.
