Universality test of the charged Higgs boson couplings at the LHC and at B factories

Abstract : Many extensions of the Standard Model (SM) of particle physics predict the existence of charged Higgs bosons. In the Minimal Supersymmetric SM (MSSM) the charged Higgs boson's couplings to fermions are proportional to tan(beta) and the fermionic mass factors, and these could be substantial at large tan(beta) and/or for heavy fermions. For this reason one may be able to observe the effect of a charged Higgs boson at the LHC and at B-factories. In this work we perform a study of the charged Higgs boson couplings at the LHC and at B-factories for a large range of tan(beta). We further argue that, for an illustrative parameter space, by combining four possible measurements at the LHC and at B-factories one can perform universality tests of the charged Higgs boson couplings to quarks.
