Combined analysis of single and double meson photoproduction with the operator expansion method — •Andrey Sarantsev — Nussallee 14-16, Bonn, 53115, Germany

The Lorentz invariant method for construction of partial wave amplitudes for pion-N and photoproduction reactions is presented. In the case of single meson production the method coincides with standard multipole approach but provides a natural extension for the analysis of multibody final states. The first results of combined analysis of photoproduction data taken by the Crystal Barrel collaboration at ELSA are discussed.
