Higgs production modes
Weboverwhelming direct production of bb quark pairs, as predicted by quantum chromodynamics (QCD). For this reason, present searches target the so-called ‘VH production’ mode, in which the Higgs boson is produced in association with a heavy vector boson, V, namely a W or a Z boson, identified via its leptonic decay. WebIn this lecture, I discuss all possible ways of Higgs production with their Feynman diagram: Gluon fusion, Higgs strahlung, Vector Boson fusion and Top fusio...
