Phase-shift analysis of π+π--scattering between 1.0 and 1.8 GeV based on fixed momentum transfer analyticity. II

Final results are presented for a ππ phase shift analysis based on extrapolated moments obtained from the 17 GeV/c CERN-Munich experiment on π-p→π+π-n. Compared to the previous publication the final results show no important qualitative change but the numerical accuracy is considerably improved as a result of using modified techniques both in the fixed-momentum transfer analysis and in the phase shift analysis. As a result, various deceases of the old solution have been cured. The authors analyze in some detail the coupling of the rho'(1600) to 2π, clearly seen in the solution. It is argued that the technique has solved the phase shift ambiguities previously obtained and details are given of the solution which has a very good chi2 to the data as well as a high numerical consistency with fixed-t, fixed-u and fixed-s analyticity.
