Dark Matter Stability from residual flavour symmetries
Giacomo Landini, Simone Marciano, Federico Mescia
We propose a model-independent framework in which Dark Matter stability emerges naturally from residual discrete symmetries left unbroken by the spontaneous breaking…
Constraining the Neutrino Mixing Matrix via Single-Sector Charged-Lepton Rotations in the JUNO Precision Era
Alessio Giarnetti, Simone Marciano, Davide Meloni
The unprecedented precision now being achieved in the measurement of the Pontecorvo--Maki--Nakagawa--Sakata (PMNS) lepton mixing matrix opens a new window onto the underlying struc…
Generalised Casas-Ibarra Parametrisation for Majorana Neutrino Masses
Juan Herrero-García, Simone Marciano, Juan Racker +1
We present a simple and broadly applicable extension of the Casas-Ibarra parametrisation that captures the structure of all Majorana neutrino mass models. Building directly on the…
A Roadmap for neutrino charge assignments in Flavor Models: Implications for LFV processes and leptonic anomalous magnetic moments
A. Giarnetti, S. Marciano, D. Meloni +1
We build upon a simple model of flavor, in which all fermion masses and mixing hierarchies arise from powers of two small parameters controlling breaking. In the…
Probing Long-Range Forces in Neutrino Oscillations at the ESSnuSB Experiment
ESSnuSB, :, J. Aguilar +97
Neutrino oscillations constitute an excellent tool to probe physics beyond the Standard Model. In this paper, we investigate the potential of the ESSnuSB experiment to constrain th…
Exploring new physics with DUNE high energy flux: the case of Lorentz Invariance Violation, Large Extra Dimensions and Long Range Forces
Alessio Giarnetti, Simone Marciano, Davide Meloni
DUNE is a next-generation long-baseline neutrino oscillation experiment. It is expected to measure with an unprecedent precision the atmospheric oscillation parameters, including t…
On quark-lepton mixing and the leptonic CP violation
Alessio Giarnetti, Simone Marciano, Davide Meloni
In the absence of a Grand Unified Theory framework, connecting the values of the mixing parameters in the quark and lepton sector is a difficult task, unless one introduces ad-hoc…
Minimal seesaw and leptogenesis with the smallest modular finite group
Simone Marciano, Davide Meloni, Matteo Parriciatu
We propose a model for leptons based on the smallest modular finite group that, for the first time, accounts for both the hints of large low-energy CP-violation in t…
Neutrino masses from new seesaw models: Low-scale variants and phenomenological implications
Alessio Giarnetti, Juan Herrero-Garcia, Simone Marciano +2
With just the Standard Model Higgs doublet, there are only three types of seesaw models that generate light Majorana neutrino masses at tree level after electroweak spontaneous sym…
Neutrino masses from new Weinberg-like operators: Phenomenology of TeV scalar multiplets
Alessio Giarnetti, Juan Herrero-Garcia, Simone Marciano +2
The unique dimension- effective operator, , known as the Weinberg operator, generates tiny Majorana masses for neutrinos after electroweak spontaneous symmetry breaking. I…
Neutrino Mixing and Leptogenesis in a model
Giorgio Arcadi, Simone Marciano, Davide Meloni
We present a simple extension of the Standard Model with three right-handed neutrinos in a SUSY framework, with an additional U(1 abelian flavor symmetry with a non sta…
