Query: Higgs decays in supersymmetric models with light neutralinos   In the Minimal Supersymmetric Standard Model, neutralinos lighter than 50 GeV
are compatible with all accelerator, precision, and cosmological bounds. Such
neutralinos might constitute a relevant decay channel for the Higgs boson,
modifying its expected signatures at hadron colliders. We study the branching
ratio h --> \chi\chi and determine the region in the supersymmetric parameter
space where it is sizable. We have found that, in fact, the Higgs may
dominantly decay into neutralino pairs. Besides, as a result of this new
channel, the branching ratio into visible modes, such as h --> \gamma\gamma,
gets suppressed.
