Transverse mass observables for charged Higgs searches at hadron colliders

Abstract

Charged Higgs boson may be produced at hadron colliders via the decay of top quarks. At the LHC, The large production cross section of top quarks pairs will make it one of the earliest channels allowing to search for physics beyond the standard model. Assuming the decay $H^{+}\to {\tau }^{+}\nu$, previous searches have so far considered only hadronic tau decays. Here we show that by using appropriate kinematical variables (transverse mass observables), leptonic tau decays can be used as well, for both observing and possibly measuring the mass of the charged Higgs boson. This can increase the overall experimental sensitivity to charged Higgs bosons at hadron colliders.
