Description
The interpretation of the enhancement of the electric dipole sum rule due to the ρ exchange potential is discussed in terms of virtual ρ photoproduction. It is explicitly shown that only a Higgs mechanism for the SU(2)xU(1) (isospin x charge) group under consideration, allows the construction of the elementary gauge invariant ρ photoproduction amplitude, fulfilling the rho transversality condition.
