Chapter 219: Liu Feng's Ambition
5 quark state particles and 1.1346TeV resonance state particles, who has more influence, if Liu Feng does not know what kind of particle the latter is, maybe he is more inclined to the latter, and he will never behave so lightly.
However, the fact is that the latter is just a high-quality particle formed in a special state, and what can it do other than to show that there is indeed a new physics, which is not a fact.
The discovery of 5-quark particles is different.
What is the point of looking for particles with 5 quark states, or more than 3 quark states?
To explain this, we have to start with quarks.
Quark is a kind of basic particle, which has the properties of mass, electric charge, color charge, and also has several existence properties such as upper quark, lower quark, odd quark, charm quark, top quark, and bottom quark.
Due to the quark confinement effect, quarks have never been observed to exist alone, and several quarks can work together to form composite particles, called hadrons.
Hadrons that are made up of one quark and one antiquark together are called mesons.
Hadrons that are made up of three quarks are called baryons.
However, until now, in the world of high-energy physics, the particles we have seen have been in the three-quark state (such as protons and neutrons) and the two-quark state.
According to the principle of quantum chromodynamics of the Standard Model, it is not excluded that there are polyquark states composed of 4 or more quarks, so this kind of polyquark particles are also called "peculiar hadrons" by scientists.
Although the "peculiar hadron" has been predicted for a long time, scientists have been exploring the possibility of its appearance, and there are even several suspected "peculiar hadron" discoveries:
For example, in 97, theoretical physicists Makqin Polyakov, Viktor Petrov and Dmitry Tyaknov of the Institute of Nuclear Physics of the St. Petersburg Academy of Sciences predicted the existence of a five-quark particle consisting of two upper quarks, two lower quarks and one odd quark, and named this particle Θ+;
Then in 2000, several experiments claimed that the five-quark state was revealed.
In particular, in 2003, the "Spring-8 Laser Electron Photon Experiment" completed by the Spring-8 Synchrotron Radiation Facility in Dongying showed a resonance state with a mass of 1.540 MeV and a significant difference of 4.6σ, and the results obtained were consistent with the theoretical predictions of Polyakov et al. in '97.
But before that, the "peculiar hadron" was still in the "science fiction" stage as a whole.
According to the theories of high-energy physicists, quarks are bound together by a strong force that causes all the color charges to cancel each other out.
Thus, in the meson, the quark must be paired with the anti-quark of the anti-color charge, and in the baryon, the three quarks must choose a different color charge from each of the three color charges, for example, red, blue, and green.
In a five-quark particle, the color charges must cancel each other out, and the only possible combination is to have one quark of one color, another quark of another, two quarks of the third color, and the last quark the anti-color of the third color.
If the existence of pentaquark particles can be discovered, then mankind's understanding of strong interaction forces will be further refreshed and expanded.
Even these "exotic hadrons" and "antimatter" outside of the Standard Model theory have always been regarded by scientists as a breakthrough in a series of major problems involving both the micro and the macro.
If they are found, it will mean that there are strange substances in the universe, and many of the existing basic theories of physics and astronomy will have to be significantly revised, so as to further understand the origin and development of the universe.
These dazzling "unusual" substances challenge the human perception of the origin of the world, and allow us to examine the inherent existence from another perspective.
Of course, these are all meanings for today's physics community, but for Liu Feng, why did he go to great lengths to find these particles?
Not to mention the status he has achieved in the chemical community, especially in the area of reverse osmosis membrane materials, even if he can't make a single achievement from today, he can lie down and gain a series of major reputations and benefits;
It is said that through his continuous absorption of high-energy physics knowledge and the analysis of the working principle and composition of the Beijing Positron Collider and the LHCb Large Hadron Collider at CERN, he has been able to simulate the working environment of the Super Collider and conduct collision experiments by himself.
That's right, in terms of experimental hanging, with the help of the ability to control the particles of the microscopic world, through the continuous simulation in the past few months, failure after failure, and exceeding the limit of the body's load again and again, he finally safely developed another practical plug-in - the Super Collider simulation experiment!
The title of 'Little Prince of Experiments' has finally crossed from chemistry to physics.
Of course, it also made Liu Feng's control of the microscopic world double from controlling about 10 cubic objects to now being able to control 20 cubic meters, and the control distance has also increased from about 10 meters away from the body to 20 meters.
Originally, since the last time he could manipulate chemistry experiments, his ability had suddenly increased by a factor of 10, from 1 cubic to 10 cubic meters;
However, the further he went, the less his ability grew stronger, and no matter how much he worked on his ability at 10 cubes, his ability control barely grew.
It wasn't until the moment he was able to perfectly simulate the crash experiment of the Super Collider that it grew from 10 cubic meters to 20 cubic meters in an instant, as if his ability was inherently used to simulate scientific experiments......
Back to the point.
The reason why Liu Feng still has to look for these 'obvious' new particles is, on the one hand, because of the battle of will.
At the beginning, he witnessed the discrimination of theoretical physicists in China abroad, and wanted to fight for the high-energy physics community in China and prove that Chinese people are no worse than anyone else!
On the other hand, he did not mean to 'fertilize and fuel' the high-energy physics of the whole world.
The Standard Model theory proposed by Yang Lao has dominated the field of high-energy physics for more than half a century.
Until now, however, the high-energy physics community on Earth has been almost still circling within the framework of his old man.
4 quark state particles have not yet been discovered, and the presence of Higgs dice has not been confirmed......
If we wait for those people to collide step by step and accumulate little by little, I don't know how many years it will take to make a substantial breakthrough!
Not to mention the need to look for dark matter and antimatter beyond the Standard Model.
Anyway, Liu Feng can't wait for the rapid development of basic physics on the earth.
The reason why he keeps introducing new particles is to draw a perfect end to the Standard Model theory!
Then, the new theories he summed up were released one after another, and high-energy physicists from all over the world were gathered to confirm the correctness of the new theories for him, and then promoted the rapid development of the basic physics of the entire earth.
This is Liu Feng's purpose, and it is his ambition!
On the contrary, whether he won the award or not, it didn't matter to him at all, and he didn't care about it anymore;
Some things can be done according to the trend, but he always doesn't believe that all scientists on the earth are blind......
This search for 5 quark state particles should be regarded as the first step he took to promote the rapid development of high-energy physics!
