Resumen:
The so called ’inconsistence’ of the off-shell propagation of 1/2 components is clearly present, in other cases as is the W boson off-shell propagation. Within this simple model, the fitting achieved with the C couplings are clearly better than those obtained with G ones.  Seems not possible accommodate the parameters of the ó meson (those of ñ are fixed in both approaches by low energy phenomenology) to get identical results with both types of couplings. The problem is not closed.
