We show that a 750 GeV di-photon excess as reported by the ATLAS and CMSexperiments can be reproduced by the Minimal Dirac Gaugino SupersymmetricStandard Model (MDGSSM) without the need of any ad-hoc addition of new states.The scalar resonance is identified with the spin-0 partner of the Dirac bino.We perform a thorough analysis of constraints coming from the mixing of thescalar with the Higgs boson, the stability of the vacuum and the requirement ofperturbativity of the couplings up to very high energy scales. We exhibitexamples of regions of the parameter space that respect all the constraintswhile reproducing the excess. We point out how trilinear couplings that areexpected to arise in supersymmetry-breaking mediation scenarios, but wereignored in the previous literature on the subject, play an important role.
