On the Maximal CP Violation in Leptogenesis with Two Right Handed Neutrinos
Swapnil Dutta
We present a generalized exact analytical expression for the upper bound on the CP-violating decay asymmetry in the case of standard vanilla leptogenesis within the minimal type-I…

Majoron Dark Matter, High-Scale Seesaw, and Leptogenesis
Brian Batell, Arnab Dasgupta, Swapnil Dutta +1
We study the cosmology and observational probes of majoron dark matter in a high-scale seesaw framework with spontaneously broken lepton number. Right-handed neutrinos naturally ge…
