Description
Phenomenological fits to low-energy π-nucleus scattering have uniformly required a greatly enhanced s-wave repulsion in the optical potential, for which no satisfactory theoretical explanation has been given. Evaluation of nonlinear terms in field-theoretic Lagrangians with broken chiral symmetry and inclusion of necessary binding effects leads to a substantial, repulsive rho2(r) potential, even on an isospin zero target. This potential may account for the previously unexplained effect
