The Minimal Massive Majoron Seesaw Model
Arturo de Giorgi, Luca Merlo, Xavier Ponce Díaz +1
A convincing explanation of the smallness of neutrino masses is represented by the Type-I Seesaw mechanism, where the two measured neutrino mass differences can be generated by int…
Early Universe hypercharge breaking and neutrino mass generation
Sergio López-Zurdo, Álvaro Lozano-Onrubia, Luca Merlo +1
We show that the conditions allowing for a spontaneous breaking of the hypercharge gauge symmetry of the Standard Model (SM) in the early Universe are generically present…
Low Seesaw Scale Solution for and
A. de Giorgi, L. Merlo, S. Pokorski
In this short talk, we present a renormalizable model that can i) generate neutrino masses via a low-scale seesaw mechanism and ii) solve the long-standing and the more r…
Flavour and Higgs physics in -symmetric 2HD models near the decoupling limit
Arturo de Giorgi, Fotis Koutroulis, Luca Merlo +1
With no evidence of any exotic particle detected so far beyond the Standard Model, the new physics may lie above the presently accessible energies at colliders and, at low-energies…
Probing HNL-ALP couplings at colliders
Arturo de Giorgi, Luca Merlo, Jean-Loup Tastet
Axion-like particles (ALPs) and heavy neutral leptons (HNLs) are both well-motivated extensions of the Standard Model. As ALPs couple to on-shell fermions proportionally to their m…
The Low-Scale Seesaw Solution to the and Anomalies
Arturo de Giorgi, Luca Merlo, Stefan Pokorski
The recent CDF-II measurement of the -boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the contex…
