Supersymmetry without a light Higgs boson at the CERN LHC

We analyze the LHC phenomenology of lambda SUSY - a version of the next-to-minimal supersymmetric standard model with a large-ish SH1H2 coupling. The scalar spectrum of the model contains a 200-300 GeV Higgs boson h with standard-model like properties, and heavy CP-even and CP-odd Higgs bosons H and A with masses in 500 - 800 GeV range. We study the discovery potential of H and A in the decay chains H -> hh -> 4V -> 2l6j and A -> Zh -> Z2V -> 2l4j. The dominant backgrounds are the diffuse Z6j and Z4j productions, which can be suppressed by demanding reconstruction of V's and h's in intermediate states. The excess of signal events allows for a discovery of both H and A with over 5 sigma significance for 100 fb(-1) of integrated luminosity.
