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…
Minimal Multi-Majoron Model
Bowen Fu, Anish Ghoshal, Stephen F. King
In order to provide a natural framework for hierarchical right-handed neutrinos, we propose a realistic ultraviolet complete minimal multi-Majoron model (MMMM). We consider two rig…
Natural neutrino mass hierarchy in a theory of gauge flavour deconstruction
Mario Fernández Navarro, Stephen F. King, Avelino Vicente
We show how a natural neutrino mass hierarchy with large lepton mixing angles may be achieved in a theory of gauge flavour deconstruction. Hitherto it has been shown that neutrino…
Right-handed neutrinos: seesaw models and signatures
Stephen F King
We give a pedagogical introduction to right-handed neutrinos as a simple extension to the Standard Model (SM), focussing on seesaw models and their possible experimental signatures…
Leptogenesis with Majoron Dark Matter
Stephen F. King, Soumen Kumar Manna, Rishav Roshan +1
We discuss a model of neutrino mass based on the type I seesaw mechanism embedded in a spontaneously broken global lepton number framework with a symmetry. We show that the r…
Modular Family Symmetry in Fluxed GUTs
Vasileios Basiouris, Miguel Crispim Romão, Stephen F. King +1
We discuss modular family symmetry in effective theories based on generic properties of bottom-up local F-theory inspired GUTs broken by fluxes, which we refer to as Fluxed GUTs. W…
Leptogenesis in Realistic Flipped SU(5)
Stephen F. King, George K. Leontaris, Luca Marsili +1
We study thermal leptogenesis in realistic supersymmetric flipped unification. As up-type quarks and neutrinos are arranged in the same multiplets, they exhibit…
Cosmological Implications of Neutrino Mass
S. F. King
I discuss the cosmological implications of neutrino mass including the cosmological relic density and dark matter, the galaxy structure limits on neutrino mass, nucleosynthesis, su…
String Inspired Neutrino Mass Models
S. F. King
I discuss a class of hierarchical neutrino mass models based on the see-saw mechanism with single right-handed neutrino dominance. I apply this mechanism to a string inspired SUSY…
