Theory of the off-shell pion-nucleon t matrix
Journal Article
·
· Phys. Rev. Lett.; (United States)
A theory of the off-shell ..pi..N t matrix is proposed. The theory, which employs dispersion-theoretic techniques, incorporates the on-shell information, including the inelasticities, and derives the additional information required to continue off shell from the underlying field theory. Results are presented for the P-wave states and are compared with those of other approaches.
