Event Details & Abstract: 

With the discovery of a Higgs Boson at the LHC, there is the possibility that the Higgs sector is not made up of a single physical boson. At CMS, we have been searching for additional Higgs-like states with masses up to 1 TeV. I will present results from these searches in the semi-leptonic H -> WW -> lvqq final state. This challenging state is able to produce limits from near the WW threshold all the way up to 1 TeV using various techniques including analysis of boosted jet sub-structure. We are able to exclude a large portion of the phase space for an additional electroweak singlet model and interpret our results in terms of a generic search for a scalar particle with a width less than or equal to the Higgs width.
