Description
We extend the Standard Model with 3 right-handed neutrinos with
an approximate lepton number symmetry, which leads to sizeable
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.
