Abstract

We analyze the conditions for the presence of light neutral Higgs scalars in a class of low-energy N = 1 supergravity models where the SU(2)L × U(1) gauge-symmetry breaking is induced by renormalization effects. We study the implications on the mass of such light scalars arising from their possible emission in the flavor-changing transition b → s + H. Gluino and chargino exchange contributions are considered and shown to be sizeably large. It is argued that a lower bound of about 4 GeV on the scalar mass may be inferred from the present experimental data, barring contrived choices of the relevant supersymmetric parameters.
