  Motivated by the recent excess in the diphoton invariant mass near 750 GeV,
we explore a supersymmetric extension of the Standard Model that includes the
minimal set of superpartners as well as additional Dirac partner chiral
superfields in the adjoint representation for each gauge group. The bino
partner pseudoscalar is identified as the 750 GeV resonance, while
superpotential interactions between it and the gluino (wino) partners yield
production via gluon fusion (decay to photon pairs) at one-loop. The gauginos
and these additional adjoint superpartners are married by a Dirac mass and must
also have Majorana masses. While a large wino partner Majorana mass is
necessary to explain the excess, the gluino can be approximately Dirac-like,
providing benefits consistent with being both "supersoft" (loop corrections to
the scalar masses from Dirac gauginos are free of logarithmic enhancements) and
"supersafe" (the experimental limits on the squark/gluino masses can be relaxed
due to the reduced production rate). Consistency with the measured Standard
Model-like Higgs boson mass is imposed, and a numerical exploration of the
parameter space is provided. Models that can account for the diphoton excess
are additionally characterized by having couplings that can remain perturbative
up to very high scales, while remaining consistent with experimental
constraints, the Higgs boson mass, and an electroweak scale which is not
excessively fine tuned.
