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 ... Web30 de jun. de 2024 · Many of the couplings of the Higgs boson could be measured to a precision of 1.5–4%, including the Higgs–top quark to a precision of 3% (currently known to 11%).
