Description
We extend the Standard Model with 3 right-handed neutrinos with an approximate lepton number symmetry, which leads to sizable neutrino mixing while generating the neutrino masses and PMNS matrix measured in oscillation experiments.
Constraints on the right-handed neutrino mixing are derived through a global fit to electroweak precision observables. We analyze explicitly the impact of one-loop corrections on these constraints.
