pp → A → Zh and the wrong-sign limit of the two-Higgs-doublet model

Ferreira, Pedro M.; Liebler, Stefan; Wittbrodt, Jonas

We point out the importance of the decay channels A → Zh and H → VV in the wrong-sign limit of the two-Higgs-doublet model (2HDM) of type II. They can be the dominant decay modes at moderate values of tan β, even if the (pseudo)scalar mass is above the threshold where the decay into a pair of top quarks is kinematically open. Accordingly, large cross sections pp → A → Zh and pp → H → VV are obtained and currently probed by the LHC experiments, yielding conclusive statements about the remaining parameter space of the wrong-sign limit. In addition, mild excesses—as recently found in the ATLAS analysis b¯b → A → Zh—could be explained. The wrong-sign limit makes other important testable predictions for the light Higgs boson couplings.
