Chapter 171 Restarting the Collision Experiment
On October 10, when 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 at CERN, 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 CERN, 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 collider scientific research funds, and 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 piece 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 needs to be determined by physicists through discussion.
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 be of great value, it may even change CERN's 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 CERN's 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 preparations. The Swiss and French troops stationed at CERN have skillfully persuaded tourists or environmental protection organizations who came to 'visit' away.
Then find out the 'talents' who got into CERN from nowhere, or even sneaked into the orbit of the underground collider.
There is no way, who made the previous person in charge of CERN 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.
At a public press conference, he proudly showed off that the LHC had created a miniature black hole.
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 "CERN is creating black holes, the earth will be swallowed up, and humanity will be destroyed soon" 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 the LHC was launched.
As time goes by, Western people increasingly believe that the LHC will destroy the earth and cause the destruction of mankind.
Then the streets began to march and protest.
Some people who are not afraid of death will even try every means to sneak into the underground of CERN to destroy the Large Strong Particle Collider.
This phenomenon, let alone now, will still exist at CERN 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 survives into old age after being struck by a high-energy particle beam from a particle accelerator.
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 in the LHC, I am afraid it will be protested and shut down, at least for a period of time.
Even though this is not CERN's responsibility, there are warning signs written near the Large Strong Particle Collider.
Of course, this unexpected black hole incident did not bring all bad news to CERN.
Colliders can create black holes, and ordinary people may be panicked, but it is different for countries.
The subsequent upgrade of the 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 currents flowed from the wires into the Large Strong Particle Collider. Superconducting magnets that are cryogenically frozen using liquid nitrogen and helium generate a strong ring-shaped magnetic field, and then use the electric field to accelerate charged particles.
The accelerated charged particles moving in the magnetic field will experience the Lorentz force. The Lorentz force causes the charged particles to move in a circular motion, thereby achieving repeated acceleration close to the speed of light.
This is how 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 only based on the basics. In terms of actual details, the gap between the two is still quite large.
Two beams of high-energy light carrying more than one trillion electron volts continue to advance and accelerate in the 27-kilometer-long acceleration tube, 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 the 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.
He followed the CERN team members and stood in the front-line laboratory. Standing beside him were three leading academicians from Nanjing University, Hua University of Science and Technology, and Jiaotong University.
This is the first line of data received from the particle collider, and any data captured by the detector will be displayed 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 based on 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 ushered in 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 he was sent back to his hometown before he had time to continue studying anything after that, or even before he could study how to capture and utilize dark matter and dark energy.
But the achievements he created are still dazzling 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 were a previous life, he might still be confused among the large amount of signal data.
After all, these data are only initial data, which have only undergone preliminary processing, which is dense, cumbersome 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 high mathematical abilities 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 data, and most of this data will be discarded after being screened 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 optimal search decay channel for the coupling of Higgs and third-generation heavy quark Yukawa was calculated by Xu Chuan, and he has certain rights of suggestion and processing.
However, in addition to the three universities in China, other universities and laboratories also applied for collision data and were approved.
This may seem a bit biased, but it is a normal thing at CERN.
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, Huaguo 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 at CERN. Everyone will apply for projects that they are interested in. After applying, CERN will allocate them 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 group to submit an acceptance report and get it approved will always get the right to sign, this is so realistic and cruel at CERN.
At the end of the experiment, the collision data processed by the supercomputer was distributed to the team 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, the Fermi National Accelerator Laboratory in the United States ranks first, the German Electron Synchrotron Institute ranks second, and three universities in China 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, so it can be said that the other two laboratories and research institutes are destined to accompany him.
After the data was distributed, a research team formed by three domestic universities began work immediately.
Three academicians + one Fields Medal candidate + several CERN researchers are a super luxurious lineup. In addition, there are always doctoral students, postdoctoral fellows, and even university professors as backup energy sources, which is destined for this experiment. Data analysis can make data fly quickly.
After working overtime, the complete Darize 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. They immediately submitted an application for the acceptance report meeting to CERN.
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 shame if other laboratories stole the results.
