  Affleck-Dine (AD) mechanism for leptogenesis involves the cosmological
evolution of a complex scalar field (AD field) that carries non-zero lepton
number. We show how explicit lepton number breaking terms, which involve the AD
field needed to implement this scenario combined with fermionic WIMP dark
matter, can generate neutrino mass at the one loop level, thus providing a
unified framework for solving four major puzzles of the standard model i.e.
inflation, baryogenesis, dark matter and neutrino mass. We discuss some
phenomenological implications of this model.
