to the particles in the loop, g$_{i}$ denotes the coupling and λ ≡ ( M 4 W + Δ 4 − 2Σ $^{2}$M2 $_{W}$) /M 4 W . A sum over all the allowed flavors and color degeneracies is explicitly included. Since the schemes consider the particles in the loop to be on-shell, the flavors include all the leptons and the u , d , s and c quarks. Proceeding along the same lines of the W gauge boson, we obtain the modifications to the ρ meson form factors, taking the complete expressions for the modified vertex computed in [11]: • Magnetic dipole moment • Electric quadrupole moment • Isospin limit Let us show, just for illustration, the above expressions in the case of m = m $^{′}$. They become where λ$_{I}$ = ( M 4 W − 2Σ $^{2}$M2 $_{W}$) /M 4 $_{W}$.
