Fermion mass relations in one-parameter modular models
Salvador Centelles Chuliá, Xueqi Li, Xiang-Gan Liu +2
Modular flavour symmetries provide a possible organizing principle for the Standard Model Yukawa sector, by replacing generic couplings with a potentially small number of modular f…
Quark hierarchies and CP violation from the Siegel modular group
M. Carducci, D. Meloni, M. Parriciatu +1
We investigate theories of flavour based on genus modular invariance and analyze how fermion mass hierarchies can be generated in this context, in the vicinity of invariant p…
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…
Supernova flavour conversions in DUNE: the slow, the fast and the standard
A. Giarnetti, J. T. Penedo
The flavour composition of a future supernova neutrino signal is expected to carry measurable imprints of flavour conversion processes in the dense stellar medium. In this work, we…
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…
Vector-like quark doublets, weak-basis invariants and CP violation
F. Albergaria, J. F. Bastos, B. Belfatto +4
We study Standard Model extensions with isodoublet vector-like quarks with standard charges. Their presence induces right-handed charged and neutral currents. We identify minimal s…
