Production of Charged Higgs Boson Pairs in Gluon-Gluon Collisions

Abstract

The search for charged Higgs bosons, which are predicted in supersymmetric theories, is difficult at hadron colliders if the mass is large. In this paper we present the theoretical set-up for the production of charged Higgs boson pairs at the LHC in gluon-gluon collisions: $pp -> gg -> H^+ H^-$. When established experimentally, the trilinear couplings between charged and neutral CP-even Higgs bosons, $H^+ H^- h^0$ and $H^+ H^- H^0$, can be measured.
