Large mass splittings between charged and neutral Higgs bosons in the MSSM

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, MSUSY, and have significant consequences for MSSM Higgs searches at future colliders.
