The Higgs boson may dominantly decay to four light jets through a light pseudoscalar 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. Utilizing jet substructure techniques, we find that for buried Higgses in the 100-120 GeV range, a 5σ discovery can be expected with roughly 10-25fb-1 of data at ECM=14TeV. For lighter Higgs bosons, the signal is contaminated by hadronically decaying W bosons, and discovery remains an unsolved challenge.
