Web5 de mai. de 2014 · A better way of putting it is that the Higgs field permits the fermions to have mass. The masses of the gauge bosons are M W = ½vg M Z = ½v√ (g 2 + g' 2) where v=246 GeV is the vacuum expectation value of the Higgs field, and g and g' are the weak coupling constants. The masses are proportional to v, but not determined by it. Web10 de abr. de 2016 · It is now established that the major source of electroweak symmetry breaking (EWSB) is due to the observed Higgs particle. However, whether the Higgs mechanism is responsible for the generation of all the fermion masses, in particular, the fermions of the first two generations, is an open question.

Web31 de mar. de 2014 · Physicists at CERN’s Large Hadron Collider (LHC) have reported new results showing that the “Higgs-like” boson discovered in 2012 is indeed consistent with expectations for a standard model Higgs boson (sometimes called the “God Particle”). The Higgs mechanism was incorporated into modern particle physics by Steven Weinberg and Abdus Salam, and is an essential part of the Standard Model. In the Standard Model, at temperatures high enough that electroweak symmetry is unbroken, all elementary particles are massless. At a critical temperature, the Higgs field develops a vacuum expectation value; the symmetry is spontaneously broken by tachyon condensation, and the W a… WebThrough spontaneous symmetry breaking, these fermions acquire a mass proportional to the vacuum expectation value of the Higgs field.
