Single-channel fits and K-matrix constraints

Nuclear Theory 2008-11-26 v2

Abstract

A K-matrix formalism is used to relate single-channel and multi-channel fits. We show how the single-channel formalism changes as new hadronic channels become accessible. These relations are compared to those commonly used to fit pseudoscalar meson photoproduction data.
