Generating μ and Bμ in models with Dirac gauginos

Abstract

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 μ and Bμ 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 κ 3 S 3 and discuss the implications for the spectrum of the model.
