Probing general models with non-universal lepton charges at FASER/FASER2, COHERENT and long-baseline oscillation experiments
Tobias Felkl, Tong Li, Jiajun Liao +1
The general anomaly-free models allow non-universal lepton charges. We explore the sensitivities of FASER/FASER2, COHERENT and DUNE/T2HK precision experiments to the new ga…

The Singly-Charged Scalar Singlet as the Origin of Neutrino Masses
Tobias Felkl, Juan Herrero-Garcia, Michael A. Schmidt
We consider the generation of neutrino masses via a singly-charged scalar singlet. Under general assumptions we identify two distinct structures for the neutrino mass matrix. This…
