Covariant four-dimensional scattering equations for the $NN-\pi NN$ system

Nuclear Theory 2009-04-17 v3

Abstract

We derive a set of coupled four-dimensional integral equations for the NNπNNNN-\pi NN system using our modified version of the Taylor method of classification-of-diagrams. These equations are covariant, obey two and three-body unitarity and contain subtraction terms which eliminate the double-counting present in some previous four-dimensional NNπNNNN-\pi NN equations. The equations are then recast into a from convenient for computation by grouping the subtraction terms together and obtaining a set of two-fragment scattering equations for the amplitudes of interest.
