Description

A scheme of parametrization of π πS and P partial wave amplitudes is proposed. Analytic, crossing and unitarity properties are rigorously satisfied. The analyticity property is made explicit by the use of a conformally mapped variable. The expression fits excellently with both phase shift and inelastic curves for centre of mass energy up to 1.4 GeV. (author)
