英文摘要 | Within the relativistic quantum field theory, we analyze the differences between the πN reaction models constructed from using (1) three-dimensional reductions of the Bethe-Salpeter Equation, (2) the method of unitary ransformation, and (3) time-ordered perturbation theory. Their relations with the approach based on the dispersion relations of S-matrix theory are dicusssed. |
