Supersymmetry with a sister Higgs boson

Within the context of supersymmetric theories, explaining a 125 GeV Higgs motivates a consideration of a broader range of models. We consider a simple addition to the MSSM of a \Sister Higgs" ( d), a Higgs eld that participates in electroweak symmetry breaking but does not give any direct masses to Standard Model matter elds. While a relatively minor addition, the phe
