DETECTING HIGGS-BOSON DECAYS TO NEUTRALINOS AT HADRON SUPERCOLLIDERS

We examine prospects for detecting the neutral Higgs bosons of minimal supersymmetric models (MSSM's) when their decays into neutralino pair s are kinematically allowed. The best signature appears to be H(h), H( p) --> Z2Z2 --> 4l + E(T). We argue that standard model contributions to this signature are negligible, and examine regions of MSSM paramete r space where the four lepton mode should be observable at the CERN La rge Hadron Collider. The same signal can also come from continuum neut ralino pair production. We propose a set of cuts to illustrate that th e neutralino decay mode of the Higgs bosons provides a viable signal o ver a substantial range of model parameters, and show that it may be s eparable from continuum neutralino production if sufficient integrated luminosity can be accumulated.
