SUSY digs up a buried Higgs

Abstract:

The Higgs boson may dominantly decay to 4 light jets through a light pseudo-scalar intermediary: h → 2η → 4j, making reconstruction at the LHC particularly challenging. We explore the phenomenology of such "Buried Higgs" scenarios in which the primary discovery channel of the Higgs is in cascade decays of superpartners. QCD backgrounds that would otherwise overwhelm the Higgs decay are suppressed by the requirement of high pT jets, and large missing transverse momentum that are the typical signatures of TeV scale supersymmetry. We also discuss utilizing jet substructure techniques to isolate the Higgs signal from hadronically decaying SM electroweak gauge bosons.
