Abstract

Extensions of the standard model Higgs sector involving weak isotriplet scalars are not only benchmark candidates to reconcile observed anomalies of the recently discovered Higgs-like particle, but also exhibit a vast parameter space, for which the lightest Higgs' phenomenology turns out to be very similar to the standard model one. A generic prediction of this model class is the appearance of exotic doubly charged scalar particles. In this paper we adapt existing dilepton+missing energy+jets measurements in the context of supersymmetry searches to the dominant decay mode H±±→W±W± and find that the LHC already starts probing the model's parameter space. A simple modification toward signatures typical of weak boson fusion searches allows us to formulate even tighter constraints with the 7 TeV LHC data set. A corresponding analysis of this channel performed at 14 TeV center-of-mass energy will constrain the model over the entire parameter space and facilitate potential H±±→W ±W± discoveries. © 2013 American Physical Society.
