Experimental study of the γp→π0ηp reaction with the A2 setup at the Mainz Microtron
The data available from the A2 Collaboration at MAMI were analyzed to select the gamma p -> pi(0) eta p reaction on an event-by-event basis, which allows for partial-wave analyses of three-body final states to obtain more reliable results, compared to fits to measured distributions. These data provide the world's best statistical accuracy in the energy range from threshold to E-gamma = 1.45 GeV, allowing a finer energy binning in the measurement of all observables needed for understanding the reaction dynamics. The results obtained for themeasured observables are compared to existing models, and the impact from the new data is checked by the fit with the revised Mainz model.
