Although he didn't succeed, the night was not without success for Lu Qiujian. At least after a night of fun in the bar, he quickly became involved with the senior players on the team; although he only participated in tactical training

There was a slight dissatisfaction, but after seeing Lu Qiujian's incredible performance in the joint training, Kahn, Ballack and others accepted the fact that he was already a member of Bayern.

The first round of this year's Bundesliga started in early August. Lu Qiujian explained to Magath that his school was relatively busy, and his debut would probably have to wait until the first home game at the end of August or early September; Magath was helpless.

Agree.

On the one hand, the reason for asking for leave is that he is busy with the school's research work, but on the other hand, it is not suitable to mention it. Mid-August is the beginning of the Olympic Games, and his not participating in the Olympics has accumulated a lot of negative effects; if Yao

Ming led the Chinese men's basketball team to fight hard in Greece, but he was abusing the situation with Bayern, allowing people with ulterior motives to interpret it. This is very bad for him.

I'm afraid the majority of fans don't feel the same way. They only think that since they have time to play for Bayern, why can't they go to Greece to participate in the Olympics? They also don't understand that Lu Qiujian's laboratory work is relatively heavy and it is basically impossible.

The reason why I have time to go to Greece for a half-month campaign.

So I might as well not participate in competitions at all during this period, and work hard to write two papers, so that I can have something to say after I make my debut in the Bundesliga in September.

As for Magath, there is another reason. Lu Qiujian only has 90 days of work-study time every year, and he is strong enough. It is better to wait until the middle and late stages of the season to use this precious weapon. If it is not easy,

We have entered the knockout stage of the Champions League, but Lu Qiujian's work-study time has run out. How can he be depressed to death?

In addition to the above reasons, while Kahn, Ballack and others were actively training and ready to start the new season, Lu Qiujian was sitting in front of the computer in the physics laboratory of the University of Munich, quickly processing various data.

At the current stage of the development of physics, people are paying attention to both the macroscopic and microscopic aspects. On the macroscopic aspect, there are equipment such as the Hubble Space Telescope to observe changes in the universe, and on the microscopic aspect, large colliders such as the LHC break the solid core of particles.

Produce smaller stable and unstable particles. Then observe and study these particles. In short, we use higher energy physics to detect smaller substances.

So why doesn't Lu Qiujian quickly find a collider and start testing? On the one hand, the collider consumes a huge amount of energy each time it is run. At the same time, the collider needs to be maintained and repaired after the test. The high cost of testing makes CRN a wealthy person.

The research center cannot conduct experiments frequently.

On the other hand, each test will generate a large amount of data, and it will take a long time to analyze and study these data; for example, let’s take the LHC as an example. The entire LHC is the Large Hadron Collider, which is the largest in the world.

The highest-energy particle accelerator is a high-energy physics device that accelerates protons into collisions.

The LHC's ring tunnel is 27 kilometers long, and the total weight of the equipment exceeds 50,000 tons. The strong magnetic field generated by the superconducting electromagnet cooled to close to absolute zero accelerates the proton beam in the ring tunnel. Finally, it reaches the level of 100 billion electron volts.

The energy collides and smashes the particles, and the energy and momentum of a bunch of initial and final state particles are recorded by five detectors: the detector, the trajectory tracker, the electromagnetic energy storage device, the hadron energy storage device, and the muon detector.

.

Then there is the data analysis work that Lu Qiujian is currently doing, "reverse" the process mentioned above for these final state particles, and "reconstruct" the intermediate state particles. Of course, the specific process is very complicated and obscure, and what everyone needs to know is

These experiments are all looking for microscopic particles that have not yet been discovered, and these particles will be reflected in the data that Lu Qiujian is currently processing.

If you can find something strange in this vast sea of ​​data, then congratulations, you have discovered something that countless physicists have been waiting for. Honors and praise will come to you quickly; of course, the premise is that your discovery is accurate

Correct. It is not a problem with the experimental equipment or an error in your analysis.

Ting Zhaozhong won the Nobel Prize with Richter in 1975 for the discovery of the j particle, and Pell and Reines won the Nobel Prize in 1995 for the discovery of the t lepton and neutrino. These are all the results of this kind of experiment.

So what is the particle that people most hope to discover today? There is no doubt that it is the Higgs boson, which is commonly known as the God particle.

In 1964, British physicist Peter Higgs published an academic theoretical article proposing the existence of a particle field and predicting the existence of a boson that can attract other particles and thereby produce mass. He believed that this boson

Chromons are the source of mass of matter, and are the basis for the formation of mass such as electrons and quarks. Other particles swim in the field formed by such particles and generate inertia, thereby forming mass and constructing the world.

Why is the God particle so important? Because it is considered to be the particle that gives the universe mass. It is also related to the final gap in the Standard Model of high-energy physics.

There is such a cartoon, the palace representing matter and interaction is composed of three basic pillars dynamic model, they are space-time dynamics (Einstein field equation), quantum gauge field (Yang-Mills equation), qcd mass generation

Mechanism (Higgs mechanism).

Among them, the pillars representing space-time dynamics and the quantum gauge field are solid and perfect, but the one representing the Higgs mechanism was depicted by the cartoonist as a crutch used by disabled people.

This cartoon vividly illustrates that the biggest problem with the incompleteness of the matter and interaction model lies in the Higgs mechanism.

There are many reasons why the Higgs mechanism is portrayed like this. First of all, it looks ugly and does not conform to the aesthetics of most physicists! Being affected by image problems not only happens in the film and television circles, but also in the physics community.

; Just like the Einstein field equations, another basic pillar, they are beautiful, so even if there are various problems, such as they cannot be solved, such as there must be a singularity failure, for example, dark energy must be introduced to explain the appearance of our universe.

, or countless people love it, protect it, and believe in it.

In addition, the Higgs mechanism also has shortcomings such as symmetry breaking, structural problems, etc., but the most important thing is the lack of tangible evidence! That is the discovery of the Higgs boson.
