Boson

in the microscopic world, there is a class of particles called bosons, such as photons, particles, hydrogen atoms and so on, they have integer spin (0,1, ... ...), their energy state can only take discrete quantum states, but allows the same number of bosons occupies a state.

Introduction to regulate the type of boson boson particle spin bosons and fermions the Higgs boson intermediate vector boson boson About

bosons (boson), named after the Indian physicist Bose.. Boson [1] (boson) is in accordance with the Bose - Einstein statistics for integer spin particles. Pauli exclusion principle of non-compliance. Can occur at low temperature Bose - Einstein condensate. Consistent with Bose - Einstein statistics: bosons formed by the full isolation of the same system, in thermal equilibrium, the distribution of particles in the energy level εi number, Ni = gi / (e ^ (α + βεi) -1). α is the Lagrange multiplier, β = 1 / (kT), the system temperature, particle density and particle quality of decisions. εi as the energy level i,onitsuka tiger online store, gi is the degeneracy of energy levels. Comply with the Bose - Einstein statistics, micro-particles. Boson is 0 or integer spin, such as photons, π mesons and so on. By the even number of bosons or fermions spin composite particles is 0 or an integer, so they are bosons. Gauge bosons of quantum field theory that the basic interactions between particles through the exchange of certain particles to pass, that the basic particle interactions are transmitted by the media, such media referred to as gauge boson particle. Sub-transmission medium is the gravitational interaction graviton g, is the quantum gravitational field, it is quality of spin zero for the two particles. Higgs and the graviton particle is theoretically predicted in the experiments are not yet direct evidence of the existence of two particles. Boson Higgs boson type

gluons - the strong interaction of medium particles, spin 1, 8 species of the passing of the quark gluon interaction between the color medium particles, is the Two different colors through quark gluon states closer together, so must be the color of the gluon. Photons - particles of electromagnetic interactions of the media, spin 1, only 1 species. g and the intermediate boson (w +, w-and z0) are the electromagnetic interaction and weak interaction of the media sub, in the electroweak unified theory, these four particles are electroweak quantum effects, which are zero-mass particles. However, due to symmetry breaking, only a medium for children (g photons) to maintain the zero-mass,asics onitsuka tiger mexico 66 baja, while the other three was a great quality. Resulting symmetry breaking mechanism, known as Higgs (higgs) mechanism. So in theory sure there must be a particle called the Higgs particle. These elementary particles in the universe In such a quantum world, all the members have their own calibration of the quantum properties of the four basic properties: mass, energy,timberland shoes outlet, magnetic moment and spin.

(right drawing: Zhang Jia) of the four properties of particles which spin, the spin of the property is the most important, it is divided into the Kingdom of the different kinds of particles of two different class, as if the world because of ######, the human into man and woman as significant. Unlike the spin of particles as a continuous rotation of the earth, but the spin, hop hop. According to the different spin times, scientists are divided into elementary bosons and fermions in two categories. Fermions is the same as e-particles, a half-integer spin (such as 1 / 2, 3 / 2, 5 / 2, etc.); while bosons are the same as the photon particles have integer spin (such as 0,1 , 2,asics kinsei 2, etc.). The spin difference between the fermions and bosons have very different characteristics. No two fermions can have the same quantum state: they do not have the same characteristics, nor in the same place at the same time; and bosons was able to have the same characteristics. All the material particles elementary particles are fermions, constitute the raw material (such as the electronic lepton to form protons and neutrons, quarks, neutrinos); and transfer force of the particles (photons, mesons, plastic son, W and Z bosons) are bosons. Bosons and fermions

particles according to the high density or low temperature collective behavior can be divided into two different categories: one is the Fermions, named after the Italian physicist fees meters, and the other is the boson, named after the Indian physicist Bose. Distinguish between these two important characteristics of the particles is spin. A particle with spin angular momentum (roughly speaking, is the product of radius and momentum) associated with the inherent nature. Revealed by quantum mechanics, an important point is that spin is quantized, which means that it can only take an integer multiple of Planck's constant (bosons such as photons, mesons, etc.) or semi-integer multiple of (fermions such as electrons, protons, etc.). Fermions and bosons follow different statistical laws. The former follows the Fermi - Dirac statistics, one of the striking and characteristic is the Pauli Swiss scientists in 1925 discovered the more than in the charge, momentum, and spin the same direction and so on fermions. It's like cinema seats, each seat can only accommodate one person. The boson is completely different, a quantum state can hold an infinite number of bosons. Therefore, it is also possible that only bosons Bose - Einstein condensate phenomenon. For example, two isotopes of lithium and lithium-6 lithium-7 are fermions and bosons. Pictures were displayed in the 810,510 and 240nk lithium and lithium-6 gas atoms and atomic clouds 7 photos. We can see that Li 7 (left), as the temperature decreases the share of smaller size, which is the place to rally, while the lithium-6 (right), the size remained stable, not in the condensate. This is because the Pauli exclusion principle the limit, so that the two fermions can not occupy the same space at the same time. For this reason, only the final white dwarf collapses under gravity to a limit size without any further narrowed. Higgs boson

It has long been found between the vastly different nature of the interaction of objects, can be simply divided into 4 kinds of force: the gravitational, electromagnetic, strong nuclear force to maintain and produce radioactive decay of the weak force. In Einstein's theory of relativity to solve the gravity problem, people began to try to build a unified model to explain the interaction force after the passage of all the 3 particles. After a long research and exploration, the scientists set up known as the But the To repair defects, Higgs proposed the existence of the Higgs field, and thus predicted the existence of the Higgs boson. It was assumed that the Higgs boson is the mass of the source of electrons and quarks to form the basis of quality, etc.. Other particles in the Higgs boson in the form of ocean cruising, the inertia generated by its role in Seoul, and ultimately have the quality. The standard model predicted the existence of 62 particles, and have been largely experimental and more confirmed, the Higgs boson is the last undiscovered elementary particles. Thus,vibram five fingers moc, the Higgs boson is nature itself, not manufactured. With the Higgs boson, the unified theory is completely established, there will be more understanding the world is therefore in Vientiane, the scientific world will no doubt be more perfect. Some have called the Higgs boson particle physics than being the Intermediate vector boson

intermediate vector boson particle delivery vector weak interaction. Early in the 20th century, 40 years have raised the role of the weak intermediate boson W ± by passing thoughts. 60's unified electroweak theory in addition to the charged intermediate boson W ±, but also there may be a neutral intermediate boson Z0. 1973 experiment with the observation of the existence of neutral weak current, is an important electroweak unified theory support. Theoretically predicted intermediate boson mass of 80 electron volts Kyrgyzstan (GeV) or so, life is short in 10-17 seconds. 1983 W ± particles has observed and Z0 particles, W ± particle mass 80.8GeV, Z0 particle mass 92.9GeV. According to later experimentally measured data, the W ± particles and particle mass m and Z0 decay width Γ of the experimental values ​​were mw = 80.3GeV, mz = 91.163GeV; Γw = 2.20GeV, Γz = 2.537GeV. Decay width can be calculated based on the life of their order of 10-25 seconds. Atlas Atlas entry for more reference materials 1
