Abstract

Using fixed-t dispersion relations, low-energy phase shifts (or s-channel resonances), and the imaginary parts of the s-channel helicity amplitudes of analyses at 6 GeV, we determine the real parts, the differential cross sections, and the polarizations for π−p→π0n at several energies. The approach is parameter-free and almost model-independent, and leads to results in agreement with experiment and with amplitude analyses.
