Description

Title of program: PIPIT Catalogue Id: ABIH_v1_0 Nature of problem Angular distributions for the elastic scattering of pions are generated by summing a partial wave series. The elastic T-matrix elements for each partial wave are obtained by solving a relativistic Lippmann- Schwinger equation in momentum space using a matrix inversion technique. The Coulomb interaction is included essentially exactly using the method of Vincent and Phatak. The piN amplitude is obtained from phase shift information on-shell and incorporates a separable off-shell form factor to en ...
