Supersymmetric models with Dirac masses for the gauginos have both a
solid top-down theoretical motivation and a rich phenomenology. We show
that the 750 GeV di-photon excess can be explained by the Minimal Dirac
Gaugino Supersymmetric Standard Model without introducing any additional
"ad-hoc" states. In this model, the resonance is identified with the
scalar partner of the Dirac bino. We demonstrate that the 750 GeV excess
can be achieved in this model while satisfying constraints arising from
the scalar mixing with the Higgs boson, vacuum stability, gauge coupling
unification and perturbativity of the couplings up to the GUT scale.
Considering different benchmark scenarios, we will present how this
model is able to produce the intriguing 750 GeV di-photon signature.
