Certain parameter regions favor exotic quark contributions over top quarks.
The study identifies conditions where exotic quark loops dominate Higgs production.
Abstract
We study the possibility of discovering neutral scalar Higgs bosons in the -extended supersymmetric standard model (USSM) at the CERN Large Hadron Collider (LHC), by examining their productions via the exotic quark loop in the gluon fusion process at leading order. It is possible in some parameter region that the neutral scalar Higgs bosons may have stronger couplings with the exotic quarks than with top quark. In this case, the exotic quarks may contribute more significantly than top quark in productions of the neutral scalar Higgs bosons in the gluon fusion process. We find that there is indeed some parameter region in the USSM that supports our speculations.
