Abstract

We show that large (> 100 GeV) mass splittings between the charged Higgs boson (H^±) and the neutral Higgs bosons (H⁰ and A⁰) are possible in the Minimal Supersymmetric Standard Model (MSSM). Such splittings occur when the μ parameter is considerably larger than the common SUSY scale, M_SUSY, and have significant consequences for MSSM Higgs searches at future colliders.
