Abstract
In this work, we explore the possibility of leptogenesis beyond the standard Yukawa-mediated decays by considering a scenario where effective electromagnetic dipole operators that connect the light and heavy neutrinos play an important role. Through these operators, new decay channels for the postulated heavy neutrinos are opened up, and consequently, such L- and CP-violating processes can lead to the generation of the correct baryon asymmetry of the universe. In addition, it has been found that the relationship of the leptogenesis scale to the light neutrino masses is very similar to that for the standard leptogenesis setup.
