Dirac Gauginos: A User Manual

The issue of a Majorana, Dirac or pseudo-Dirac mass for gauginos must not be reduced to a question of an extension of the Minimal Supersymmetric Standard Model by extra states, parameters and phenomenological implications. On the contrary, it is intimately related to the fundamental issue of the realization of new symmetries in nature, R-symmetries. We present here a very dense compilation of the main features of models with (pseudo-)Dirac gauginos.
