Single-channel fits and K-matrix constraints
arXiv:nucl-th/0510025 · doi:10.1103/PhysRevC.74.055207
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.
