A Non-singularity form Factor of Baryon Vertex for Crossing Channel Study

  • A New relativistic and singularity free baryon form factor for crossing channel study is proposed. This new form factor satisfies the crossing symmetry law of strongly interacting particle scattering amplitudes transfered from t-channel to s-channel or the inverse.
