Chapter 170: Restart the Collision Experiment

On October 10, when the migrant workers who had spent the National Day returned to work, Xuchuan, thousands of miles away, also ushered in the restart of the LHC Large Strong Particle Collider.

The 10-day overhaul and maintenance was finally completed and the final stage of preparation began.

Countless physicists gathered, waiting for this experiment.

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

If successful, it will be a major revolution for the entire high-energy physics community.

Mathematics is perfectly integrated into physics, and it is cool to control the information about the collision of particles in mathematics.

For the high-energy physics community, if this approach is successful, then it has value in generalizing.

Spend some brainpower to save millions or even tens of millions of dollars in collision research for the collider, and any lab will do it.

Just like the first person to eat a crab, although it may be difficult, as long as someone does it first, it is always a lot easier for the latecomer.

On the other hand, high-energy particle collision experiments are about exploring a certain particle or object phenomenon, and the data produced is not necessarily all about the target particle or target phenomenon.

In the random collision of particle beams, something strange or something new is created that has never been discovered before.

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

Especially now that the last plank of the Standard Model has been filled, the physics community is more eager to discover something beyond the Standard Model.

Whether the data produced by the collision experiments are useful or not, and whether they are outside the Standard Model, needs to be discussed by physicists to determine.

It can even be said that for researchers and physicists from all over the world, the second thing is more attractive.

If a new discovery is confirmed to be of great value, it may even change the established research plan and become the next research target of the Large Intense Particle Collider.

Like the Higgs particle, it has been one of the main research targets in the 21st century.

It is not only the completion of the Standard Model, but also the exploration and discovery of the origin of mass, the Higgs field, dark matter and dark energy.

......

The Large Strong Particle Collider (LHC) is in its final stages of preparation, and the troops stationed in Sweden and France are very skilled in dissuading tourists and environmental groups who come to visit.

Then the 'talents' who don't know where to get in, or even dive into the orbit of the underground collider, are pulled out.

No way, who made the previous person in charge a 'little cutie'.

In '07, before the LHC was upgraded, the head of Euratom was not the current Professor David Gross, but another cutie who liked to joke a little.

At a public press conference, he proudly showed off that LHC had created a miniature black hole.

Although he later explained that this kind of miniature black hole can only exist in the collision pipe for less than 0.000001 seconds after its appearance, and does not pose any harm to the earth, it still made big news at the time.

There were many media reporters present at the time, and this discourse that should have been a show off the powerful performance of LHC equipment was finally distorted into various versions of the news by these unscrupulous media.

What "make black holes, the Earth is about to be swallowed, humanity is about to be destroyed" "The Large Hadron Collider is making black holes that could grow and swallow the Earth. This kind of news was all over the Internet and various newspapers at the time.

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

In addition, some idle and boring ones have collected some earthquakes, floods, and disasters that occurred all over the world when LHC was activated.

As time passed, the people of the West became more and more convinced that LHC would destroy the earth and cause the destruction of mankind.

Then began to march all over the streets, protesting.

Some people who are not afraid of death will even try their best to sneak into the underground to destroy the large strong particle collider.

This phenomenon, let alone now, will still exist even if it is another ten years.

Therefore, Sweden and France arranged for troops to be stationed here, and before each experiment was opened, a clearance was carried out.

lest a fool sneak into the underground collider.

Not to mention the destruction of the large strong particle collider, or the bombardment of a running accelerator, is a big deal.

Not everyone is Anatoly Bugsky, who survives into old age after being hit by a high-energy particle beam in a particle accelerator.

Normally, a beam of high-energy particles flying at near high speed in a large strong particle collider pierces and collides, and the grave will be overgrown with grass next month.

In the event of such an accident, the LHC will probably be protested and shut down, at least for a period of time.

Even if that's not the responsibility, warning signs are written around the Large Strong Particle Collider.

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

The collider can knock out a black hole, and the general public may panic, but for the country it is different.

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

After all, for the national level, black holes have a huge attraction.

......

At 9:30 a.m., the collision experiment on the coupling phenomenon of Yukawa between Higgs and the third-generation heavy quark began on time.

Huge currents poured from the line into the large strong particle collider. Superconducting magnets, which are frozen at ultra-low temperatures by liquid nitrogen and helium, generate a strong annular magnetic field, and then use an electric field to accelerate the charged particles.

The accelerated charged particles move in a magnetic field by the Lorentz force, which causes the charged particles to move in a circular motion, thus accelerating repeatedly to approach the speed of light.

This is the principle on which the collider operates.

But microscopic particles are also limited by relativistic effects, and their speeds can only keep approaching the speed of light, but cannot reach it.

And as the velocity increases, the relativistic mass of the particle increases, and the mass-to-charge ratio becomes larger, making acceleration more and more difficult.

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

Only things that can be affected by a strong magnetic field in a ring can be used in collision experiments.

This is actually somewhat similar to controlled nuclear fusion technology.

Controlled nuclear fusion is actually controlled by ultra-high temperature plasma in the reactor through ultra-strong magnetic fields or similar technologies, and then realizes power generation.

Of course, this is only from the basics, and 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, are constantly advancing, accelerating, and colliding at the intersection in the 27-kilometer-long acceleration pipeline, producing a fierce and shining light.

These rays are captured by detectors deployed at the intersection and then evolved into data and spectral images.

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

Xu Chuan is still quite interested in the first collision experiment that can be regarded as the dominant after being reborn.

The team he followed stood in the front-line laboratory, and there were three leading academicians of Nanjing University, China University of Science and Technology, and Jiaotong University.

This is the first line of received particle collider crash data, and any data captured by the detector is shown on the display here.

If you're familiar with high-energy domains and mathematical analysis, these initial data are enough to give you a sense of something.

And in this regard, Xu Chuan will not be modest.

Not to say that it is the first or second in the world, it is at least in the top five.

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

Axial particles, dark matter, dark energy, inert neutrinos..... In the next ten years, he will be known as the first person in the field of contemporary physics with these discoveries and corresponding theories.

And even throughout modern history, he can be ranked ahead of Newton, Einstein and Maxwell.

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

Albert Einstein used the theory of relativity as a major pillar of modern physics, ushering in a new era of modern science and technology.

Maxwell, on the other hand, ushered in the information age with classical electromagnetism.

As for him, based on the theory of dark matter, dark energy combined with graviton, he subverted the traditional rules of physics and rewrote people's cognition and definition of matter.

Although after that, he didn't have time to continue researching anything, or even how to capture and use dark matter, dark energy, and was sent back to his hometown.

But the achievements of the creation continue to shine in the world.

......

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

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

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

After all, these data are only initial data, and they have only undergone preliminary processing, which is dense, cumbersome and repetitive.

But after being reborn, I don't know if it has something to do with majoring in mathematics in this life, and his sensitivity to mathematics has improved a lot.

It was an unexpected surprise indeed.

Because whether it is mathematical research, physics research, or materials research, it requires a lot of mathematical ability as the foundation.

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

After all, this data has not been processed by supercomputers, and it contains all kinds of impurities and useless data.

Xu Chuan also understood this, so he didn't pay attention to it after watching it for a while.

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

In the past two days, the collider has generated trillions of data, the vast majority of which will be sifted by supercomputers and discarded.

The rest will be reorganized and sent to the database for use by physics experts.

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

It's something that's already booked.

After all, the most ideal search for decay channels coupled between Higgs and Yukawa of the third-generation heavy quark was calculated by Xu Chuan, and he had a certain right to suggest and deal with it.

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 seem a bit biased, but it's a normal thing.

If this research shows that the most ideal search for decay channels is the coupling of Higgs and Yukawa, the third-generation heavy quark, it is a scholar from the United States or a European scholar.

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

Of course, it is not certain whether you can grab it or not.

After all, there are so many physicists, and everyone will apply for projects of interest, and after applying, they will be allocated according to your contributions and previous research.

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

Although the right of authorship is always the first team to submit the acceptance report and get it, it is so realistic and cruel.

.......

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

In addition to the three universities of Nanjing University, China University of Science and Technology, and Jiaotong University, there are also personnel from the Fermi National Accelerator Laboratory and the Germanic Electron Synchrotron Research Institute who applied for the collision data this time.

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

Of the three groups, if calculated according to strength, the Fermi National Accelerator Laboratory in the United States ranked first, the Electron Synchrotron Research Institute in Germania ranked second, and the three universities in China ranked third.

However, NYU has previous experience in analyzing the coupling collision data between Higgs and Yukawa, a third-generation heavy quark. In addition, Xu Chuan is also the author of theoretical calculation data, which can be said to be destined for the other two laboratories and research institutes to accompany him.

.......

After the data were distributed, the three domestic universities formed a scientific research team and immediately started the work.

Three academicians + a Fields Medal candidate + several are the super luxury lineup of researchers, plus there are doctoral students, postdoctoral fellows, and even university professors as backup energy at any time, which is destined to fly fast for the data analysis data of this experiment.

In less than a week, the complete Darritz diagram was drawn.

After the drawing of the Daritz diagram was completed and checked to confirm that it was correct, Xu Chuan and the three academicians did not even have time to celebrate, and submitted an application for the acceptance report meeting as soon as possible.

Although I knew that the other two labs would not be able to produce results so quickly, I was definitely still worried.

After all, if other labs steal the results of this time, it will be a fool.
