چکیده    We propose a framework of supersymmetric extensions of the standard model that can ameliorate both the susy higgs mass problem and the missing superpartner problem. new vectorlike matter fields couple to the higgs and provide new loop contributions to its mass. new yukawa couplings are sizable and large supersymmetry breaking is not needed to lift the higgs mass. to avoid a landau pole for the new yukawa couplings, these fields are charged under a new gauge group, which confines and leads to a hidden valley-like phenomenology. the hidden valley sector is almost supersymmetric and ordinary sparticles decay to exotic new states which decay back to standard model particles and gravitinos with reduced missing energy. we construct a simplified model to simulate this scenario and find a viable parameter space of specific benchmark models which ameliorates both of the major phenomenological problems with supersymmetry.
