Higgs inflation, vacuum stability, and leptogenesis
Journal of High Energy Physics, 2020 We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigated under which this model can simultaneously ensure Higgs vacuum stability

Gravitational tests of electroweak relaxation
Journal of High Energy Physics, 2021 We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated by the confinement of new strongly interacting vector-like fermions ...

Dark matter and lepton flavour phenomenology in a singlet-doublet scotogenic model
Journal of High Energy Physics, 2021 We study the dark matter phenomenology of scotogenic frameworks through a rather illustrative model extending the Standard Model by scalar and fermionic singlets and doublets.

Shining light on the scotogenic model: interplay of colliders and cosmology
Journal of High Energy Physics, 2020 In the framework of the scotogenic model, which features radiative generation of neutrino masses, we explore light dark matter scenario. Throughout the paper we chiefly focus on keV-scale dark matter which can be produced either via freeze-in through the

Physics beyond the Standard Model [PDF]
AIP Conference Proceedings, 1996 We discuss some of the signatures associated with extensions of the Standard Model related to the neutrino and electroweak symmetry breaking sectors, with and without supersymmetry. The topics include a basic discussion of the theory of neutrino mass and the corresponding extensions of the Standard Model that incorporate massive neutrinos; an overview ...

HERA physics beyond the standard model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 1999 The prospects of physics beyond the standard model in deep inelastic scattering are reviewed, emphasizing some scenarios which attained attention after the observation of an excess of events with large momentum transfer at HERA.

Probing dark matter freeze-in with long-lived particle signatures: MATHUSLA, HL-LHC and FCC-hh
Journal of High Energy Physics, 2020 Collider searches for long-lived particles yield a promising avenue to probe the freeze-in production of Dark Matter via the decay of a parent particle.

Sterile neutrino dark matter in left-right theories
Journal of High Energy Physics, 2020 SU(2) L × SU(2) R gauge symmetry requires three right-handed neutrinos (N i ), one of which, N 1, can be sufficiently stable to be dark matter. In the early universe, W R exchange with the Standard Model thermal bath keeps the right-handed neutrinos in ...

Neutrinos and collider physics
New Journal of Physics, 2015 We review the collider phenomenology of neutrino physics and the synergetic aspects at energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass mechanism. In particular, we focus on seesaw models within the minimal setup as
