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…
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…
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…
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…
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…
