Higgs production cross section

WebHiggs boson pair production is traditionally considered to be of particular interest for a measurement of the trilinear Higgs self-coupling. Yet it can offer insights into other couplings as well, since - in an effective field theory (EFT) parameterisation of potential new physics - both the production cross section and kinematical properties of the Higgs … Web1 de jul. de 2024 · The production cross section for vector-boson-fusion production, for example, is directly proportional to the square of the coupling strengths between the Higgs boson and W or Z bosons. A modification of these couplings will also affect the rate at which the Higgs boson decays to various final states.

Web9 de dez. de 2011 · First, there is p p –> H, which involves two gluons, one from each proton smashing together to make a Higgs particle (which I’ll call g g –> H). This process is curious, because gluons and Higgs particles do not directly interact with each other at all (which is why the gluon remains massless even when the Higgs field is non-zero).
