We propose an extension of the standard model with U(1)D×U(1)B-L×Z2 symmetry. With this extension of the model we assumed that the neutrinos are Dirac (i.e. B-L is an exact symmetry), and found a simultaneous solution for non zero neutrino masses, Dark Matter(DM) content and the baryon asymmetry of the Universe. The observed baryon assymmetry of the Universe explained through the Dirac leptogenesis with the assistance of DM. TheU(1)D symmetry is broken at a TeV scale and gives mass to a neutral gauge boson ZD. At one loop level this neutral gauge boson mixes with the standard model Z-boson and paves a path to detect the DM at terrestrial laboratories through spin independent elastic scattering. We explain the neutrino mass through a Lagrangian term, which softly broken by the Z2 symmetry. © 2018 Copyright owned by the author(s) under the terms of the Creative Commons.
