With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

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 …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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 …

The MEG experiment, designed to search for the μ^+ → e^+ γ μ+→ e+ γ decay, completed
data-taking in 2013 reaching a sensitivity level of 5.3 * 10^-13 5.3× 10-13 for the branching …

We review how the muon anomalous magnetic moment (g− 2) and the quest for lepton flavor
violation are intimately correlated. Indeed the decay μ→ e γ is induced by the same …

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

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 …

We review the collider phenomenology of neutrino physics and the synergetic aspects at
energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass …
