Influence of spin-rotation measurements on partial-wave analyses of elastic pion-nucleon scattering

Nuclear Theory 2008-11-26 v1

Abstract

Recent measurements of spin-rotation parameters in elastic π+p\pi^+ p scattering are in marked disagreement with predictions of the Carnegie-Mellon-Berkeley and Karlsruhe-Helsinki analyses. Using the method of Barrelet, we show how this discrepancy can be removed. We then show how this Barrelet transformation alters the partial-wave amplitudes. The effect of unitarity and analyticity constraints is also considered.
