Partially (in)visible Higgs decays at the LHC
arXiv:1209.0494 · doi:10.1016/j.physletb.2012.11.008
Abstract
Both Atlas and CMS have reported a discovery of a Standard Model-like Higgs boson of mass around 125 GeV. Consistency with the Standard Model implies the non-observation of non-SM like decay modes of the newly discovered particle. Sensitivity to such decay modes, especially when they involve partially invisible final states is currently beyond scrutiny of the LHC. We systematically study such decay channels in the form of , with a light scalar or scalar, and analyze to what extent these exotic branching fractions can be constrained by direct measurements at the LHC. While the analysis is challenging, constraints as good as can be obtained.
