Abstract

Short distance contributions to non-leptonic radiative decays arise from the presence of the gradient of the antisymmetric tensor current octet in the Wilson expansion. They can cause large SU(3) violation, preliminary evidence of which already exists for the reaction Σ+→pγ. Relations among various non-leptonic decay parameters are obtained taking proper account of such terms and some decisive tests are proposed for their existence.
