WebWe review the present status and the future prospects for the measurements of the Higgs Yukawa couplings to light quarks and charm. A special focus is given to new proposed … WebFermi's Theory was the first theoretical effort in describing nuclear decay rates for β decay. The interaction could also explain muon decay via a coupling of a muon, electron-antineutrino, muon-neutrino and electron, with the same fundamental strength of the interaction. This hypothesis was put forward by Gershtein and Zeldovich and is known ...

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 … Ver mais In the Standard Model of particle physics, the Higgs mechanism is essential to explain the generation mechanism of the property "mass" for gauge bosons. Without the Higgs mechanism, all bosons (one of the two classes of … Ver mais Background Spontaneous symmetry breaking offered a framework to introduce bosons into relativistic quantum field theories.

The measurement of the Higgs particle mass at the LHC has made the determination of the value of the Higgs self-coupling possible: with M H ≈ 125 GeV, one gets λ ≈ 1 / 8. Does this particular value imply anything special for the Standard Model, except that now books can be filled with the values of M H and λ?
