Abstract
A method of statistical testing of analyticity is applied to pion-pion shifts in order to obtain the pole positions in the second sheet of the complex energy plane for the resonances in the , , and partial waves. Whereas the positions of the dominant resonances are found at MeV, MeV, and MeV, no conclusions about the or the could be reached.
