The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

Current neutrino experiments are measuring the neutrino mixing parameters with an
unprecedented accuracy. The upcoming generation of neutrino experiments will be …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Charged lepton flavour-violating transitions would be a clear signal of new physics beyond
the Standard Model. Their search has been carried out in a variety of channels, the most …

Most of the free parameters in the Standard Model (SM)—a quantum field theory which has
successfully elucidated the behaviors of strong, weak and electromagnetic interactions of all …

A bstract High-energy lepton colliders with a centre-of-mass energy in the multi-TeV range
are currently considered among the most challenging and far-reaching future accelerator …

Large, nonstandard neutrino self-interactions have been shown to resolve the∼ 4 σ tension
in Hubble constant measurements and a milder tension in the amplitude of matter …

A bstract We present a model of radiative neutrino masses which also resolves anomalies
reported in B-meson decays,\({R} _ {D^{\left (\ast\right)}}\) and\({R} _ {K^{\left (\ast\right)}}\), as …

A general classification of flavor symmetries is provided according to their interplay with the
proper Poincaré and gauge groups and to their linear or nonlinear action in field space. The …

A bstract Models of radiative Majorana neutrino masses require new scalars and/or fermions
to induce lepton-number-violating interactions. We show that these new particles also …
