Leading divergences of weakNNρamplitudes

We apply light-cone and Bjorken-Johnson-Low limiting procedures to nonleptonic decay amplitudes describing weak virtual vector-meson emission. Reducing the vector meson from the decay state via the Lehmann-Symanzik-Zimmermann reduction formalism before applying the limiting procedures produces divergences whose coefficients do not vanish in a simple model of SU(3)-symmetry breaking. The leading divergences of the amplitudes produce a cutoff-dependent potential whose most significant feature is a coupling constant as much as two orders of magnitude larger than and of the opposite sign from that of the separable-approximation potential. Also, neutral-$\rho$-meson exchange contributes as much to the potential as charged-$\rho$ exchange. The consequences of this potential for parity-violating nuclear processes are examined.
