Dirac-Phase CP-Violation in the Low-Scale Type-I Seesaw with Three Right-Handed Neutrinos

Alessandro Granelli, Juraj Klarić, S. T. Petcov

We study the low-scale type-I seesaw with three right-handed neutrinos (i.e. heavy Majorana neutrinos) when the CP-violation arises solely from the low-energy Dirac phase of t…

The meV frontier of neutrinoless double beta decay in the JUNO era

J. T. Penedo, S. T. Petcov

Observing neutrinoless double beta decay would establish lepton number violation and the Majorana nature of neutrinos. Within the standard 3-flavour paradigm, the rate of this proc…

Viability of , and Flavour Symmetries in Light of the First JUNO Result

S. T. Petcov, A. V. Titov

We update the analysis of the viability of the lepton mixing patterns originating from , and discrete flavour symmetries and leading to predictions for the solar n…

Quark Flavour Model in the Vicinity of the Fixed Point

S. T. Petcov, M. Tanimoto

We study in the bottom-up framework the possibility to generate the quark mass hierarchies without fine-tuning, the quark mixing and CP-violation (CPV) in a flavour model with $S^\…

Discrete flavour and CP symmetries in light of JUNO and neutrino global fit

Gui-Jun Ding, Cai-Chang Li, Jun-Nan Lu +1

Working within the reference three-neutrino mixing framework, we confront the lepton mixing predictions derived using non-Abelian discrete flavour and CP symmetries with the first…

Modular-symmetry-protected seesaw

A. Granelli, D. Meloni, M. Parriciatu +2

In the presence of a finite modular flavour symmetry, fermion mass hierarchies may be generated by a slight deviation of the modulus from a symmetric point. We point out that this…
