Generating mu and B mu in models with Dirac gauginos

We consider the extension of the Minimal Supersymmetric Standard Model by Dirac masses for the gauginos. We study the possibility that the same singlet S that pairs up with the bino. to form a Dirac fermion, is used to generate it and Bit terms through its vacuum expectation value. For this purpose. we assume that, in the Higgs potential. the necessary R-symmetry breaking originates entirely from a superpotential term (kappa)/S-3(3) and discuss the implications for the spectrum of the model.
