Query: Dark matter assisted Dirac leptogenesis and neutrino mass   We propose a minimal extension of the standard model with U(1)_{B-L} \times
Z_{2} symmetry. In this model by assuming that the neutrinos are Dirac (i.e.
$B-L$ is an exact symmetry), we found a simultaneous solution for non zero
neutrino masses and dark matter content of the universe. The observed baryon
asymmetry of the universe is also explained using Dirac Leptogenesis, which is
assisted by a dark sector, gauged under a U(1)_D symmetry. The latter symmetry
of the dark sector is broken at a TeV scale and thereby giving mass to a
neutral gauge boson Z_D. The standard model Z-boson mixes with the gauge boson
Z_D at one loop level and thus paves a way to detect the dark matter through
spin independent elastic scattering at terrestrial laboratories.
