Higgs Boson

The Higgs boson or Higgs particle is an elementary particle proposed in the Standard Model of particle physics. It is named in honor of Peter Higgs who, along with others, proposed in 1964, now called the Higgs mechanism to explain the origin of mass of elementary particles. The Higgs boson is the quantum of the Higgs field, (the smallest possible field excitation). Under the proposed model, has no spin, electric charge or color, is very unstable and quickly decays, its half-life is around zeptosegundo. In some variants of the Standard Model bosons can be several Higgs.
The existence of the Higgs boson and the associated Higgs field would be the simplest of several methods Standard Model of particle physics that attempt to explain the reason for the existence of mass in elementary particles. This theory suggests that a field permeates all space, and elementary particles acquire mass interact with it, while those who do not interact with it, do not. In particular, this mechanism justifies the enormous mass of the W and Z vector bosons, as well as the absence of mass of the photon. Both W and Z particles, like the photon is massless bosons own, the first showing a huge mass that interact strongly with the Higgs field, and the photon shows no mass at all because it does not interact with the Higgs field.
The Higgs boson has been a long search in particle physics. If proved its existence, the model would be complete. If it is established that there is, other proposed models in which the Higgs is not involved could be considered.
On July 4, 2012, CERN announced the observation of a new particle "consistent with the Higgs boson," but it would take more time and data to confirmarlo.1 The March 14, 2013 CERN, with two times more data at its disposal in the announcement of the discovery in July 2012, found that the new particle is seen increasingly as the Higgs boson. The way you interact with other particles and their quantum properties, along with measures interactions with other particles, strongly indicate that a Higgs boson. There remains the question of whether the Higgs Standard Model Higgs or perhaps the lightest of several bosons predicted in some theories that go beyond the Standard Model.
