... massless1.2
There is now strong evidence from the Super-Kamiokande experiment that the neutrinos may not be massless[1,2,3,4]. Thus they must exist in both helicity states.

...$ g^{z}_{4}$3.1
The coupling parameterisation given here is taken from [35]. It should be noted that the equivalent parameter to $ g^{z}_{4}$ in [36] would be $ -\hat{\hat{\kappa}}_{\rm Z}$.

... energies3.2
It should be noted that if the scale of new physics is less than 1 TeV, or if there is no light Higgs, then terms with higher dimensions cannot be neglected [47].

...eq:amplitude3.3
It should be noted that each term in column one does not directly relate to a single coupling in equation 3.1. This is because the terms in table 3.2 were derived in [41], who use a slightly different parameter set.

This holds true even if the anomalous coupling is CP-violating.
