    "abstract": "The Fubini-Furlan-Rossetti sum rule for pion photoproduction on the nucleon\nis evaluated by dispersion relations at constant t, and the corrections to the\nsum rule due to the finite pion mass are calculated. Near threshold these\ncorrections turn out to be large due to pion-loop effects, whereas the sum rule\nvalue is closely approached if the dispersion integrals are evaluated for\nsub-threshold kinematics. This extension to the unphysical region provides a\nunique framework to determine the low-energy constants of chiral perturbation\ntheory by global properties of the excitation spectrum.",
