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

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.

Physics beyond the standard model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2000 The Standard Model is in good shape, apart possibly from g_μ- 2 and some niggling doubts about the electroweak data. Something like a Higgs boson is required to provide particle masses, but theorists are actively considering alternatives. The problems of flavour, unification and quantum gravity will require physics beyond the Standard Model, and ...

Beyond the Standard Model physics at CLIC [PDF]
International Journal of Modern Physics A, 2020 A summary of the recent results from CERN Yellow Report on the CLIC potential for new physics is presented. Greater emphasis is put on the direct search for new physics scenarios motivated by the open issues of the Standard Model as well as on interpretations of Standard Model measurements as probes of new physics in the context of effective field ...

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 ...

Dark matter, dark radiation and gravitational waves from mirror Higgs parity
Journal of High Energy Physics, 2020 An exact parity replicates the Standard Model giving a Mirror Standard Model, SM ↔ SM ′ . This “Higgs Parity” and the mirror electroweak symmetry are spontaneously broken by the mirror Higgs, 〈H ′〉 = v ′ ≫ 〈H〉, yielding the Standard Model Higgs as a ...

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

Neutrinos and physics beyond the standard model [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 A brief sketch is made of the present observational status of neutrino physics, with emphasis on the hints that follow from solar and atmospheric neutrino observations, as well as cosmological data on the amplitude of primordial density fluctuations. I also briefly review the ways to account for the observed anomalies and some of their implications.
