  We consider a mirror world scenario, in which light Dirac neutrinos are
generated from a seesaw mechanism and leptogenesis occurs at high scale without
violating lepton number. After leptogenesis, the conservation laws of the
theory imply the visible baryon-minus-lepton asymmetry to be equal to the
mirror baryon-minus-lepton asymmetry. We extend previous work by presenting a
detailed study of this Dirac leptogenesis mechanism by constructing the full
set of Boltzmann Equations for both cases of unflavored and flavored regimes.
We show that $Z_2$ breaking and lepton/mirror lepton flavor effects can be
exploited to enhance the final baryon-minus-lepton asymmetry in our world by
several orders of magnitude.
