Analytic properties of the crossing matrix between kinematic-singularity-free helicity amplitudes for pion production
Journal Article

· Phys. Rev., D; (United States)
We determine the crossing matrix between regularized helicity amplitudes for pion production and show that this matrix is analytic apart from poles in the continued crossed-channel c.m. energy, corresponding to poles in the crossed-channel amplitudes.
