The Landscape of Composite Higgs Models
Mikael Chala, Renato Fonseca
We classify all different composite Higgs models (CHMs) characterised by the coset space of compact semi-simple Lie groups and inv…
Gauge vectors and double beta decay
Renato M. Fonseca, Martin Hirsch
We discuss contributions to neutrinoless double beta () decay involving vector bosons. The starting point is a list of all possible vector representations that may contribute…
Lepton number violation in 331 models
Renato M. Fonseca, Martin Hirsch
Different models based on the extended (331) gauge group have been proposed over the past four decades. Yet, despite being an active rese…
Small neutrino masses and gauge coupling unification
Sofiane M. Boucenna, Renato M. Fonseca, Felix Gonzalez-Canales +1
The physics responsible for gauge coupling unification may also induce small neutrino masses. We propose a novel gauge mediated radiative seesaw mechanism for calculable neutrino m…
Classification of lepton mixing patterns from finite flavour symmetries
Renato M. Fonseca, Walter Grimus
Flavour symmetries have been used to constrain both quark and lepton mixing parameters. In particular, they can be used to completely fix the mixing angles. For the lepton sector,…
