Brief on Dark Matter in the Type Ib Seesaw Model: a GeV-scale Dirac neutrino portal
Bowen Fu
The type Ib seesaw, as an alternative explanation to the origin of neutrino mass, provides a new intriguing way to connect the neutrino physics to cosmology. In this proceeding, we…

Dark Matter in the Type Ib Seesaw Model
Marco Chianese, Bowen Fu, Stephen F. King
We consider a minimal type Ib seesaw model where the effective neutrino mass operator involves two different Higgs doublets, and the two right-handed neutrinos form a heavy Dirac m…

Impact of Higgs portal on gravity-mediated production of superheavy dark matter
Marco Chianese, Bowen Fu, Stephen F. King
In the so-called Planckian Interacting Dark Matter (PIDM) scenario, superheavy dark matter particles are produced after inflation by gravity-mediated interactions through the freez…
