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 --> χχand 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 --> γγ, gets suppressed.9 pages, 5 figuresHigh Energy Physics - PhenomenologyHiggs decays in supersymmetric models with light neutralinostext
