Dirac neutrinos from Peccei-Quinn symmetry: a fresh look at the axion
Eduardo Peinado, Mario Reig, Rahul Srivastava +1
We show that a very simple solution to the strong CP problem naturally leads to Dirac neutrinos. Small effective neutrino masses emerge from a type I Dirac seesaw mechanism. Neutri…
Phenomenology of scotogenic scalar dark matter
Ivania M. Ávila, Valentina De Romeri, Laura Duarte +1
We reexamine the minimal Singlet + Triplet Scotogenic Model, where dark matter is the mediator of neutrino mass generation. We assume it to be a scalar WIMP, whose stability follow…
Flavour and CP predictions from orbifold compactification
Francisco J. de Anda, José W. F. Valle, Carlos A. Vaquera-Araujo
We propose a theory for fermion masses and mixings in which an family symmetry arises naturally from a six-dimensional spacetime after orbifold compactification. The flavour…
Gravitational footprints of massive neutrinos and lepton number breaking
Andrea Addazi, Antonino Marcianò, António P. Morais +3
We investigate the production of primordial Gravitational Waves (GWs) arising from First Order Phase Transitions (FOPTs) associated to neutrino mass generation in the context of ty…
A theory for scotogenic dark matter stabilised by residual gauge symmetry
Julio Leite, Oleg Popov, Rahul Srivastava +1
Dark matter stability can result from a residual matter-parity symmetry, following naturally from the spontaneous breaking of the gauge symmetry. Here we explore this idea in the c…
Electroweak Breaking and Higgs Boson Profile in the Simplest Linear Seesaw Model
Duarte Fontes, Jorge C. Romao, Jose W. F. Valle
We examine the simplest realization of the linear seesaw mechanism within the Standard Model gauge structure. Besides the standard scalar doublet, there are two lepton-number-carry…
