Probing the Tau Anomalous Magnetic Moment at Colliders: From Ultra-Peripheral Collisions to the Precision Frontier

Natascia Vignaroli

The anomalous magnetic moment of the tau lepton, , represents a fundamental test of the Standard Model (SM) and a high-sensitivity probe for New Physics in the third generati…

New avenues for the neutrino dipole portal exploration at the energy frontier

Natascia Vignaroli

We present a comprehensive and gauge-invariant study of the neutrino dipole portal at the energy frontier. Assuming negligible active-sterile mixing, we analyze sterile neutrino pr…

Muon collider probes of Majorana neutrino dipole moments and masses

Michele Frigerio, Natascia Vignaroli

Majorana neutrinos may have transitional dipole moments, which violate lepton number as well as lepton flavour. We estimate the sensitivity of future colliders to the electron-muon…

Improved precision in inverse beta decay cross section

Giulia Ricciardi, Natascia Vignaroli, Francesco Vissani

We analyze the cross section for inverse beta decay, focusing on the moderate energies (a few MeV to hundreds of MeV) relevant for reactor and supernova neutrinos. We discuss the u…

Majorana neutrino dipole moments and masses at a muon collider

Michele Frigerio, Natascia Vignaroli

A future multi-TeV muon collider would provide an important probe for Majorana neutrinos. A muon collider with a collision energy of 30 TeV would be sensitive to

The cross section of inverse beta decay

Giulia Ricciardi, Natascia Vignaroli, Francesco Vissani

We discuss the accuracy of the evaluation of the cross section for inverse beta decay at low energies and its relevance in the current experimental framework.
