On October 10, when the workers who had spent the National Day returned to work, Xuchuan, thousands of miles away, also welcomed the restart of the LHC Large Strong Particle Collider.
The ten-day inspection and maintenance was finally completed and the final preparation stage was entered.
Countless physicists gathered, waiting for this experiment.
On the one hand, everyone is waiting to see whether the latest collision data can correctly verify the 'optimal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks' calculated by Xu Chuan.
If it succeeds, it will be a major change for, or for the entire high-energy physics community.
Mathematics is perfectly integrated into physics, and it is so cool to control the information of mathematical calculations of particle collisions.
For the high-energy physics community, if this method can be successful, then it has the value of promotion.
Spend some brainpower to save millions or even tens of millions of collision research funds for the collider. Any laboratory 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 will always be much easier for those who come after.
On the other hand, it is a high-energy particle collision experiment that explores certain particles or object phenomena. The data generated are not necessarily all about the target particles or target phenomena.
In the random collision of particle beams, there will always be something strange or something new that has never been discovered before.
Although most of the new discoveries are useless, this cannot stop physicists from being curious about the new world.
Especially now that the last plank of the Standard Model has been completed, the physics community is even more eager to discover things beyond the Standard Model.
Whether the data generated by the collision experiment is useful and whether it is something beyond the standard model requires discussion among physicists before it can be determined.
It can even be said that for researchers and physicists from various countries, the second aspect 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 Strong Particle Collider.
Just like the Higgs particle, it has always been one of the main research targets in the 21st century.
It not only completes the standard model, but also explores and discovers the origin of mass, the Higgs field, dark matter and dark energy.
...
The Large Strong Particle Collider (LHC) has entered the final stage of preparation. The troops stationed in Switzerland and France skillfully persuaded tourists or environmental protection organizations who came to 'visit' away.
Then we will find out the 'talents' who have got into it from nowhere, or even sneaked into the orbit of the underground collider.
There is no way, who made the previous person in charge a "little cutie".
In 2007, before the LHC was upgraded, the head of the European Atomic Energy Laboratory was not the current Professor David Gross, but another cute kid who liked to joke a bit.
He once proudly showed off the creation of a miniature black hole by LHC at a public press conference.
Although he later explained that such a miniature black hole could only exist in the collision tube for less than 0.000001 seconds after its appearance and would not cause any harm to the earth, it still made big news at the time.
There were many media reporters present at the time. This was supposed to be a statement about showing off the powerful performance of the LHC equipment, but it was finally distorted into various versions of news by these unscrupulous media.
News such as "The Earth is about to be swallowed up and mankind is about to be destroyed by creating black holes," and "The Large Hadron Collider is creating black holes, and these black holes may grow and swallow the Earth." were all over the Internet and various newspapers and periodicals at that time.
This immediately caused panic among ordinary people in Europe who had not read much.
Coupled with some boredom, I collected some earthquakes, floods and other disasters that occurred around the world when LHC was started.
As time goes by, Western people believe more and more that LHC will destroy the earth and cause the destruction of mankind.
Then the streets started to be filled with demonstrations and protests.
Some people who are not afraid of death will even try every means to sneak underground to destroy the Large Strong Particle Collider.
This phenomenon, let alone now, will still be there even in ten years.
Therefore, Switzerland and France arranged for troops to be stationed here, and the area was cleared before each experiment started.
Lest some idiot sneaks into the underground collider.
Not to mention destroying the Large Strong Particle Collider, even being bombarded by a running accelerator is a big deal.
Not everyone is Anatoly Bugsky, who was hit by a high-energy particle beam from a particle accelerator and survived into old age.
Normally, if the high-energy particle beam flying at almost high speed in the Large Strong Particle Collider collides, the grave will be covered with grass next month.
Once such an accident occurs to the LHC, I am afraid it will be protested and shut down, at least for a period of time.
Even if this is not his responsibility, there are warning signs written all over the area near the Large Strong Particle Collider.
Of course, this unexpected black hole incident did not bring all bad news.
The collider can create a black hole, and ordinary people may feel panicked, but it is different for the country.
The subsequent upgrade of lhc was partly due to this.
After all, for the national level, black holes are a huge attraction.
...
At 9:30 in the morning, the collision experiment on the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks started on time.
Huge current flows from the circuit into the large strong particle collider. Superconducting magnets that are ultra-low temperature frozen through liquid nitrogen and helium generate a ring-shaped strong magnetic field, and then use the electric field to accelerate charged particles.
The accelerated charged particles will experience the Lorentz force when moving in the magnetic field. The Lorentz force causes the charged particles to move in a circular motion, thereby achieving repeated acceleration to approach the speed of light.
This is how the collider works.
However, microscopic particles are also limited by the relativistic effect, and their speed can only continue to approach the speed of light, but cannot reach the speed of light.
Moreover, as the speed 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 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 ring magnetic field can be used in collision experiments.
This is actually somewhat similar to controllable nuclear fusion technology.
Controlled nuclear fusion actually uses ultra-strong magnetic fields or similar technologies to control ultra-high-temperature plasma in the reactor, and then generate electricity.
Of course, this is just based on the basics. In terms of actual details, the gap between the two is quite large.
.....
Two beams of high-energy light carrying more than one trillion electron volts continue to advance in the 27-kilometer-long accelerating tube, accelerate, and collide at the intersection, producing a fierce and shining light.
These lights are captured by detectors deployed at the intersection, and then evolved into individual data and a pair of energy spectrum images.
With the operation of LHC, a large amount of collision experiment data appears every minute and every second.
Xu Chuan was quite interested in the first collision experiment that he could be regarded as leading after his rebirth.
The team members he followed stood in the front-line laboratory. Standing next to him were the three leading academicians from Nanjing University, Hua University of Science and Technology, and Jiaotong University.
This is the first line of received particle collider collision data, and any data captured by the detector will be presented on the display 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 ranking first or second in the world, but at least in the top five.
After all, he discovered so many things through the collider under his feet in his previous life.
Axial particles, dark matter, dark energy, sterile neutrinos, etc. In the next ten years or so, he will be known as the first person in contemporary physics with these discoveries and corresponding theories.
And even if we look at the entire modern history, the only three people who can be ranked in front of him are Newton, Einstein and Maxwell.
Newton created a new era of physics with classical mechanics, the era of classical physics.
Einstein used the theory of relativity as a pillar of modern physics and ushered in a new era of modern science and technology.
】
Maxwell ushered in the information age with classical electromagnetism.
As for him, he subverted the traditional rules of physics and rewrote people's understanding and definition of matter based on the theory of dark matter and dark energy combined with gravitons.
Although after that, he had no time to continue to study anything, or even to study how to capture and utilize dark matter and dark energy before 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 underfoot depicts signal points one by one.
Xu Chuan stared at the screen with interest, staring at the familiar data above.
If it was a previous life, he might still be confused among the large amount of signal data.
After all, these data are only initial data and have only undergone preliminary processing, which is intensive, tedious and repetitive.
But after his rebirth, I don't know if it was related to his majoring in mathematics in this life, but his sensitivity to mathematics has improved a lot.
This is indeed an unexpected surprise.
Because whether it is mathematical research, physical research, or materials research, they all require a high level of mathematical ability as a foundation.
Of course, it is almost impossible to rely on this sensitivity to find data on the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks from front-line laboratories.
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 watching it for a while.
The collision experiment was restarted in October, and the experiment on the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks lasted for two full days.
In the past two days, the collider has produced trillions of computational data, and most of this data will be discarded after screening by supercomputers.
The remaining parts will be sorted again and sent to the database for application by physics experts.
For this experiment, the first batch of applicants to apply for collision data were naturally three universities in China.
This is something that has already been scheduled.
After all, the most ideal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks was calculated by Xu Chuan, and he has certain rights of suggestion and processing.
However, in addition to the three universities in China, there are also other universities and laboratories that have also applied for collision data and been approved.
This may make people feel a little biased, but it is a normal thing now.
If the most ideal search decay channel for the Yukawa coupling of Higgs and third-generation heavy quarks is discovered this time, it will be American or European scholars.
When they obtain the right to use the first batch of data, Hua can also apply for the first batch of experimental data for processing.
Of course, it’s not certain whether you can grab it or not.
After all, there are so many physicists, and everyone will apply for projects that interest them. After application, you will be allocated based on your contribution and past research.
In addition, data calculated by two or three different groups of research institutions can be used to verify each other to ensure the correctness of the data.
Although only the first team that submits the acceptance report and gets it approved will always get the right to sign, this is such a reality and cruelty.
.......
At the end of the experiment, the collision data processed by the supercomputer were distributed to the group that applied for the experimental data.
In addition to NTU, Hua University of Science and Technology, and Jiaotong University, those who applied for collision data this time include personnel from the Fermi National Accelerator Laboratory and the German Electron Synchrotron Institute in the United States.
After all, with Xu Chuan's theoretical calculation data, the probability of discovering the Yukawa coupling phenomenon between Higgs and third-generation heavy quarks is very high. There is no reason not to come in and get a share of the pie.
In terms of strength among the three groups, America's Fermi National Accelerator Laboratory ranks first, the German Electron Synchrotron Institute ranks second, and China's three universities rank third.
However, relatively speaking, NTU has previous experience in analyzing data from the Yukawa coupling collision of Higgs and 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 dominate the other two laboratories and
The research institute is here to accompany you.
.......
After the data was distributed, a research team formed by three domestic universities began work immediately.
There are three academicians, one Fields Medal candidate, and several other researchers. In addition, there are always doctoral students, postdocs, and even university professors as backup energy sources. It is destined that this experimental data analysis can
Almost flying.
Working overtime, the complete Dalitz diagram was drawn in less than a week.
After the Dalitz diagram was drawn and checked to confirm that it was correct, Xu Chuan and the three academicians did not even have time to celebrate, and immediately submitted an application for the acceptance report meeting.
Although I know that it is impossible for the other two laboratories to produce results so quickly, I am definitely still worried.
After all, it would be a scam if other laboratories stole this result.
