The rho pole parameters
Description
The application of the analytical extrapolation method for testing the hypothesis of two complex conjugate .ooles on the second sheet of a ππ P-partial wave amplitude is studied. Numerical values of the pole parameters depend to some extent on the set of phase shifts used in the analysis. The hypothesis of two conjugate poles on the second sheet in the ππ P-wave has high confidence levels for all data sets used. The resulting values of the pole parameters are in the energy regions M: 753-770 MeV, GAMMA/2: 71-83 MeV. (author)
