Neutrino masses and Gravitational waves
Date: Wednesday, October 16th
Time: 4:00 pm
Place: 5280 Chamberlin Hall
Speaker: Oleg Popov, Korea Advanced Institute of Science and Technology, KAIST
Abstract: We present a set of minimal Dirac neutrino mass models and discuss their cosmological consequences. Specifically, such models generate a neutrino mass at tree level and can have a multiple gravitational wave signature through primordial phase transition(s), can explain the asymmetry between matter and antimatter via neutrinogenesis and accommodate a dark matter candidate in dark glueballs or dark baryons. We discuss situations where the effects on the parameter space from different cosmological considerations overlap and are complimentary to collider probes.
