Chapter 475 Higgs Boson

According to the Standard Model, the common models around us are basically composed of elementary particles.

A pair of positive and negative quarks form a meson, three quarks can form a baryon (for example, neutrons and protons are baryons, both are composed of three quarks), protons and neutrons can form the nucleus, and the nucleus plus electrons form an atom.

Atoms and atoms form molecules, and molecules and atoms can form all kinds of materials around us.

As the "God particle" that gives quality to other particles, the importance of the Higgs particle can be said to be self-evident. The Higgs particle is also unstable, and it will decay into other particles.

Scientists can deduce the nature of the Higgs particle itself by studying the products of the decay of the Higgs particle.

In 2012, people finally discovered the Higgs particle by studying two-photon products and other lepton pair products.

The physicist Higgs himself also won the Nobel Prize in Physics in 2013 for proposing the "Higgs Mechanism" named after him.

In 2012, people discovered the Higgs particle in two-photon products and other lepton pair products. After the discovery of the Higgs particle, in order to further study its properties, scientists need to measure the Higgs particle Various decays.

As the Xinhua News Agency said in the report, the Standard Model predicts that most of the Gus particles should decay to the bottom quark. This decay accounts for 60% of the Higgs decay, which means that this decay should be very common. However, it was not until 2018, six years later, that people announced the discovery of the bottom quark pair decay of the Higgs particle.

At that time, a neutral boson (Z) and a Higgs particle (H) produced by the collision of protons at that time, H decayed into a pile of bottom quarks (B), and Z decayed into a pair of positive and negative electrons (E+ E).

And this decay is too complicated. Scientists need to select a very small number of signals from a huge amount of data.

If in 2012, a teenager is looking for a **** table in a school hall with a capacity of 1,000 people, then in 2018, he will probably find his girlfriend at a concert with a capacity of 30,000 people.

In 2012, the young people also had a lot of background in the decay process, and in 2018, the background in the quark collision process was much more.

The summary of the proton collision process on the Large Hadron Collider, there are too many processes that can produce bottom quark pairs. Scientists have to distinguish from the massive data which bottom quarks come from the decay of the Higgs particles. .

The most difficult part of this discovery is to separate very few signals from a large number of backgrounds.

Scientists at the European Nuclear Center have been collecting experimental data until they finally have accumulated enough data to make the Higgs particle's decay signal at the bottom quark reach five times the standard deviation.

So at that time, a physicist could finally announce that this was a discovery "". If you want to know that the high energy physics article is to be used as a title, the significance of the signal must reach more than five times the standard deviation.

This discovery is very important, because it can be used to test the Standard Model or discover new physics, so the European Nuclear Center's discovery tells humans that the measurement results of this decay process are consistent with the predictions of the Standard Model.

This discovery is a milestone event in the process of exploring the Higgs particle. Up to now, the LHC has observed the coupling of the Higgs particle with the three generations of quarks, leptons and other major decay modes.

The Higgs particle has a very close relationship with the formation of the mass of objects in space. With mass, the particles will combine to become atoms.

Only when there are atoms can there be molecules, and when there are molecules to build objects, the "Higgs boson" is considered to be a particle that has shaped everything in the world.

Without it, there would be no world that people can see, so this is why it is called the "God particle".

The impact on humans is that such particles can be used to "build everything", and at the same time, the weight can be reduced without changing the nature of matter.

In terms of industry, a large mountain of iron can reduce it to less than one ton, and a fighter jet can reduce its weight to only one-tenth of its usual size, greatly improving its endurance.

Or maybe... to lose weight, using high-energy physics to lose weight.

You can also use the Higgs boson to make your favorite sports cars, yachts, mansions, etc., various substances.

You only need molecules of sufficient mass and enough energy to make any kind of substance constructed from molecules.

Liquid metal can also be used. The high-strength materials that Ye Fan needs can also be solved by the Higgs boson.

It is like reducing the weight of a planetary engine so that it does not directly crush the continental plates, and at the same time constructing a new type of high-strength metal, which can satisfy the future human escape.

It's just a pity that the research on the "God particle" has not broken through the substantive stage until now, and it still only stays at the theoretical stage of the particle collider.

In other words, human beings don't know how to use this kind of particles, and they are also exploring the various properties of this kind of particles and their decay.

According to the official budget of the country, it will take at least three hundred years for this technology to be substantively applied and deployed on a large scale.

It was like the DC and AC invented by Edison and Nikola Tesla at that time~www.wuxiaspot.com~ The resistance theory system invented by Ohm, until modern times, hundreds of years later, began to glow, the whole world Begin to apply related technologies on a large scale.

However, the advanced vision they put forward at the time did not spread on a large scale.

In other words, the level of social productivity at that time could not meet the need to promote this idea.

The same is true of substituting the Higgs boson into modern life. Although the thing is good, it is not needed now, nor can it be used.

Therefore, the town government directly cut down the relevant budget at the time, and at the same time did little effort to maintain the particle collider.

For so many years, the things collided by the particle collider are good in many respects, but they are things that can only be used decades later and hundreds of years later.

The town government of Qiguo didn't want to continue to burn money, burned for decades or hundreds of years, it is not good to say that, then the country will not necessarily exist.
