“…The constraints are basically the same in the complex and real 2HDM because the charged Higgs couplings to fermions coincide -see, for example, appendix C of [19]. In Type II and Flipped, Z → bb implies tan β 1 while b → sγ excludes values of m H ± below 360 GeV, at the 95% confidence level, with only a very mild dependence on tan β [23][24][25][26]. In Type I and Lepton Specific, tan β 1 still holds, but m H ± can be as low as ∼ 90GeV, even after the LHC results on pp → tt with decay into H +b [27,28].…”

Abstract:The latest LHC data confirmed the existence of a Higgs-like particle and made interesting measurements on its decays into γγ, ZZ * , W W * , τ + τ − , and bb. It is expected that a decay into Zγ might be measured at the next LHC round, for which there already exists an upper bound. The Higgs-like particle could be a mixture of scalar with a relatively large component of pseudoscalar. We compute the decay of such a mixed state into Zγ, and we study its properties in the context of the complex two Higgs doublet model, analysing the effect of the current measurements on the four versions of this model. We show that a measurement of the h → Zγ rate at a level consistent with the SM can be used to place interesting constraints on the pseudoscalar component. We also comment on the issue of a wrong sign Yukawa coupling for the bottom in Type II models.

“…It should be noted that in the Type II and flipped models, radiative B decays force the charged Higgs to be heavier than 340 GeV [7]. But new physics can weaken this bound substantially (this happens in supersymmetric models, for example) and thus we will leave open the possibility that the charged Higgs could be much lighter.…”

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 τν 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.
