"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… " - Higgs fermion

Web5 de mar. de 2024 · Abstract: In order to identify the Higgs sector using future precision data, we calculate the partial decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs and gauge-boson pairs with one-loop electroweak and one-loop QCD corrections in various extended Higgs models, such as the Higgs singlet model … WebIt is because once the Higgs couples two Weyl fermions together, they become the two chiralities of a massive charged fermion. The standard 4-component spinor formalism disguises how natural this coupling is because it makes every fermion into a Dirac fermion, and projects out the unphysical states at every vertex.
