Abstract

The discovery potential of charged Higgs from pp->tH+- in the H+- -> tau nu decay channel is investigated in CMS and ATLAS. For m_H>m_t, the most relevant channels are H+- -> tb and H+- -> tau nu. Whereas the former has the largest branching ratio it suffers of large irreducible backgrounds, while the latter offers a very clean enviroment when appropriate cuts are used. Making use of the tau polarization effects, in the purely hadronic final states an almost background-free signal is selected. The expected discovery range is evaluated for CMS and ATLAS with 30 fb^-1 each in the low luminosity running conditions and the combined results are presented.
