Models of TeV-scale baryogenesis are interesting as they provide an opportunity to probe the physics responsible for the observed matter-antimatter asymmetry of the universe at experimentally accessible energies. In this talk, I will present a minimal extension of the Standard Model that accommodates low-scale baryogenesis and review various experimental and astrophysical constraints on the model. Then I will discuss my work on identifying the parameter space for successful baryogenesis where the observed baryon asymmetry is generated without being subsequently washed out. I will also examine the prospects for probing the allowed parameter by the next generation neutron-antineutron oscillation experiments. I will conclude the talk by discussing some directions for extending this work.
