Abstract
Approximate analytical formulas for the self-consistent renormalization of P,T-odd and P-odd weak nuclear potentials by the residual nucleon-nucleon strong interaction are derived. The contact spin-flip nucleon-nucleon interaction reduces the constant of the P,T-odd potential 1.5 times for the proton and 1.8 times for the neutron. Renormalization of the P-odd potential is caused by the velocity dependent spin-flip component of the strong interaction. In the standard variant of $\pi + \rho$-exchange, the conventional strength values lead to anomalous enhancement of the P-odd potential. Moreover, the $\pi$-meson exchange contribution seems to be large enough to generate an instability (pole) in the nuclear response to a weak potential.
