  Dirac leptogenesis (or Dirac neutrinogenesis), in which neutrinos are purely
Dirac particles, is an interesting alternative to the standard leptogenesis
scenario. In its supersymmetric version, the modified form of the
superpotential required for successful baryogenesis contributes new,
generically non-flavor-diagonal terms to the slepton and sneutrino mass
matrices. In this work, we examine how current experimental bounds on
flavor-changing effects in the lepton sector (and particularly the bound on Mu
-> e Gamma) constrain Dirac leptogenesis and we find that it is capable of
succeeding with superpartner masses as low as 100 GeV. For such light scalars
and electroweakinos, upcoming experiments such as MEG are generically expected
to observe signals of lepton flavor violation.
