Abstract: (APS)

The input of a top-quark mass in the region 25-55 GeV is shown to yield quite stringent bounds on the masses of the light Higgs bosons in a minimal version of the low-energy N=1 supergravity theory with radiative breaking of electroweak symmetry. In particular, the lightest Higgs boson must weigh quite a bit less than MZ2.
