Leptogenesis with a GeV-Scale Quasi-Dirac Neutrino
Stephen F. King, Soumen Kumar Manna, Rishav Roshan +1
We discuss leptogenesis in a model with a GeV-scale quasi-Dirac neutral lepton, comprising mainly sterile states, which is accessible to future experiments. In particular, we show…

Cosmological Consequences of a Highly Decoupled Right-handed Neutrino
Stephen F. King, Rishav Roshan, Sudipta Show
In the minimal type-I seesaw, one right-handed neutrino (RHN) can decouple from neutrino mass generation. Such a state is usually neglected, yet its feeble couplings make it long-l…
