Program of measurement of the asymmetry P at the minima of the differential cross section for elastic pi(+)p scattering

摘要

A program of measurement of the polarization parameter P in elastic pi(+)p interaction in the resonance region of backward pion scattering is presented. This program is aimed at determining the bifurcation points of the trajectory of zeros of the pion-nucleon amplitude and, hence, at unambiguously reconstructing the amplitude of pi N scattering in the second resonance region. It is planned to perform a relevant experiment in a pion beam from the accelerator of the Institute of Experimental and Theoretical Physics (ITEP, Moscow). (c) 2005 Pleiades Publishing, Inc.
