Higgs' invisible branching fraction at the LHC

by Tae Min Hong (University of Pittsburgh (US))



Does the Higgs have a large invisible branching fraction? Two approaches are presented. The first is an indirect constraint of the invisible branching fraction using precision Higgs couplings measurements. The second is a direct search of invisible decays. In particular, I will discuss in detail two of ATLAS’s results: the H -> WW in VBF, which is one of the strongest inputs for the couplings and the evidence for VBF Higgs production, and the H -> invisible in VBF, which gives the strongest direct limit. Comparisons with CMS's results are made.
