Ambiguities in hard-photon theorems for radiative pi N scattering
Recently developed hard-photon theorems, used to parametrize off-shell effects in radiative pion-nucleon scattering, are shown to suffer from ambiguities in terms of order k in an expansion in photon energy. These ambiguities can be shown to arise primarily from the arbitrary choice of parameters us...
