Review of prospects for H^+ in non-SUSY multi-Higgs models in view of LHC results

TL;DR

This paper reviews the potential for detecting charged Higgs bosons in various non-SUSY multi-Higgs models, considering recent LHC results and discussing different mass scenarios and decay channels.

Contribution

It provides an updated overview of charged Higgs prospects in non-SUSY models, including new insights on decay modes and detection strategies based on LHC data as of 2012.

Findings

Charged Higgs lighter than top quark can be produced in top decays.

Heavier charged Higgs may be detected via tau-nu decay mode.

Decay into W h (125 GeV) could be the dominant channel.

Abstract

In this talk, prospects for the charged Higgs in non-SUSY models are reviewed, in view of LHC results (as of October, 2012). The four models (Type I, Type II, lepton-specific and flipped) without tree level flavor-changing neutral currents are discussed. Updates for the case in which the charged Higgs is lighter than the top, leading to production in top decays, are presented along with expectations for the future. If the charged Higgs is heavier than the top quark, detection may be possible through the tau-nu decay mode. In addition, it is pointed out that the decay of the charged Higgs into W h, where h is the 125 GeV state, may be dominant. Charged Higgs phenomenology in models which do contain tree level flavor-changing neutral currents, as well as the inert doublet model and others, are also briefly reviewed.
