Abstract

The observation that the b\ensuremath→s\ensuremathγ decay rate is close to the standard model value implies a large mass for the charged Higgs boson in the minimum supersymmetric standard model (MSSM), which nearly closes the t\ensuremath→bH⁺ decay channel. For m_t=150 GeV, the parameter region m_A\ensuremath\lesssim130 GeV is excluded; this largely preempts searches at the CERN e⁺e^\ensuremath- collider LEP II and also partially excludes a region that would be inaccessible to MSSM Higgs boson searches at LEP II and at the Superconducting Super Collider and the CERN Large Hadron Collider.
