Web8 de mar. de 2024 · Higgs self-coupling. 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? 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 ...
