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

Abstract

We show that large ($>100$ GeV) mass splittings between the charged Higgs boson ($H^{\pm }$) and the neutral Higgs bosons ($H^0$ and $A^0$) are possible in the Minimal Supersymmetric Standard Model (MSSM). Such splittings occur when the $\mu$ parameter is considerably larger than the common SUSY scale, $M_{SUSY}$, and have significant consequences for MSSM Higgs searches at future colliders.
