Parameter counting for neutrino mixing
arXiv:hep-ph/0002299 · doi:10.1007/s100520000478
Abstract
The content of physical massess, mixing angles and CP-violating phases in the lepton sector of extended standard model, both renormalizable and non-renormalizable, with arbitrary numbers of the singlet and left-handed doublet neutrinos is systematically analyzed in the weak basis.
