    "abstract": "We analyze the Fubini-Furlan-Rosetti sum rule in the framework of covariant\nbaryon chiral perturbation theory to leading one-loop accuracy and including\nnext-to-leading order polynomial contributions. We discuss the relation between\nthe subtraction constants in the invariant amplitudes and certain low-energy\nconstants employed in earlier chiral perturbation theory studies of threshold\nneutral pion photoproduction off nucleons. In particular, we consider the\ncorrections to the sum rule due to the finite pion mass and show that below the\nthreshold they agree well with determinations based on fixed-t dispersion\nrelations. We also discuss the energy dependence of the electric dipole\namplitude E_{0+}.",
