Probing Baryogenesis using Neutron-Anti-Neutron Oscillation

Abstract

Neutron-anti-neutron (=− =̄) oscillation is a baryon number violating process that requires physics beyond the Standard model. Future experiments at ESS and DUNE aim to either discover (= − =̄) oscillation or to put more stringent constraints on the oscillation time. We study the impact of such a discovery on different baryogenesis scenarios using an effective field theory framework for (= − =̄) oscillation. We also study the implications of observing the mediators at the LHC and the possibility of falsifying some of the baryogenesis scenarios in the context of some simplified UV complete scenarios.
