At proton colliders, Higgs particles are dominantly produced in the gluon--gluon fusion mechanism. The Higgs--gluons coupling is mediated by heavy quark loops, and the process can serve to count the number of heavy strongly interacting…

We review Higgs production at hadron colliders via vector-boson fusion and via gluon fusion, fully inclusively and in association with one and two jets. Then we address the issue of the measurement of the coupling of the Higgs to the vector…
The hierarchy problem and the electroweak data, together, provide a plausible motivation for considering a light Higgs emerging as a pseudo-Goldstone boson from a strongly-coupled sector. In that scenario, the rates for Higgs production and…
