Higgs production at hadron colliders as a probe of new physics
Abstract
The coupling of Higgs with gauge bosons can receive non-decoupling corrections due to heavy quanta. Deviation from the SM predictions are described by a set of parameters eV, which can be related to the parameters S,T. The Higgs production by gluon fusion can be used to probe eg, whereas its decays into WW can probe eW. The resulting bounds may imply the exclusion of heavy particles, such as additional standard or mirror families, chiral colored sextets and octet quarks. Within the MSSM, we also find that gluon fusion is a sensitive probe for the spectrum of squark masses.
