  We present formulae for the calculation of Dirac gaugino masses at leading
order in the supersymmetry breaking scale using the methods of analytic
continuation in superspace and demonstrate a link with kinetic mixing, even for
non-abelian gauginos. We illustrate the result through examples in field and
string theory. We discuss the possibility that the singlet superfield that
gives the U(1) gaugino a Dirac mass may be a modulus, and some consequences of
the D-term coupling to the scalar component. We give examples of possible
effects in colliders and astroparticle experiments if the modulus scalar
constitutes decaying dark matter.
