What is the Higgs boson?
The physics of elementary particles – not as popular as a politician or celebrity gossip, but one of its members still managed to gather the laurels. It is, of course, about the Higgs boson. July 4, 2012 CERN team announced that they had found a particle for which it was built the Large Hadron Collider. Particle, say, exactly in line with expectations of physicists concerning the Higgs boson, or as it is ungrammatical press dubbed – “God particle.” The Higgs boson is responsible for mass and excites minds. What is it?
Of course, the secret to the hype that we are a little closer to solving the mystery of the universe. Well, or want to believe so. We recently wrote about the fact that CERN physicists really find the Higgs boson , so no doubt that this is the boson remains. Another question that for his detailed study would have to build some more expensive colliders.
In order to understand what is the Higgs boson, we have to turn to one of the most famous theories describing how the work space: the Standard Model. This model came to us in the form of physical particles, fields, which gradually filled the physics building blocks as the study of the universe. It’s been happening for centuries and people have made substantial progress. First, we discovered atoms, then protons, neutrons and electrons, and finally – the quarks and leptons (more about them later). Yes, you can wipe all the pieces off the board and give quantum mechanics , but physicists stubbornly cling to the Standard Model, many of them already hate her and want to refute that will find a more comfortable and beautiful theory of how the world is constructed of elementary particles. But so far without success, and the discovery of the Higgs boson even drew off a thorough review of the SM.
As they say, hedgehogs cried and injected, but continued to eat the cactus. After all, the standard model gives us a deep understanding of the types of matter and energy, deeper than any physical theory.
The standard model was developed in the 1970s. That’s the whole point of CM in a few sentences: our universe is composed of 12 different particles of matter and the four forces. Among these 12 particles are six quarks and six leptons. Quarks form protons and neutrons, and the family of leptons include the electron and the electron neutrino – neutrally charged his antagonist. Scientists believe that the leptons and quarks are indivisible: they can not be broken down into smaller particles. Along with these particles, the Standard Model describes the four fundamental forces: gravity, electromagnets, strong and weak interactions.
As a theory, the standard model is working well, despite her inability to fit in gravity. Because of this, physicists predicted the existence of certain particles before they were discovered experimentally. And now, on the horizon appeared the Higgs boson. Find out how this particle fits into the Standard Model and the universe as a whole.
Higgs boson: the last piece of the puzzle
Scientists believe that each of the four fundamental forces of the particle has a corresponding (or bosons), which acts on the matter. It is hard to understand. We tend to think of power as a mysterious air, which is beyond being and non-being, but in reality the force is as real as matter itself.
Some physicists describe as bosons scales associated with elastic particles of matter that generates them. Using this analogy, we can imagine bosons constantly detonates with gum while tangling with other bosons in the birth of power.
Scientists believe that each of the four fundamental forces have their own specific bosons. Electromagnetic field, for example, pass through matter, the electromagnetic force of the photon. Physicists think that the Higgs boson is the same function, but it will give a lot.
But can the mother be without mass of the Higgs boson? According to the Standard Model – no. But physicists have found a solution. What if all the particles do not have their own weight, but they get it, passing through a particular field? This field is known as the Higgs field, have different effects on different particles. Photons can sneak past, but the W-and Z-bosons are bogged down in mass. In fact, the assumption of the existence of the Higgs boson says that everything has mass, interacts with the ubiquitous Higgs field, which occupies the entire universe. And as in other fields, described by the Standard Model, the Higgs particle, need their own vehicle, to influence other particles. It is called the Higgs boson.
July 4, 2012, scientists working on the Large Hadron Collider, announced that it opened a particle that behaves like the Higgs boson. You can exhale – think of physics, but it turned out that the bosons, like the Higgs can be several, which means the study at a higher level of energy will go on and on.
Remarkably, the Higgs boson was suddenly a really herald the death of the universe. The script can be found here .
