The Double π° and ω-MESON Photoproduction at Graal

(English) The Double π° and ω-Meson Photoproduction at Graal

The double π0 photoproduction off the proton has been measured in the beam energy range of 0.65 1.5GeV. The total and differential cross sections and the Σ beam asymmetry were extracted. The total cross section measured for the first time in the third resonance region of the nucleon shows a prominent peak. The interpretation of these results by two independent theoretical models infers mostly the selective excitation of P11– and D13-nucleon resonances.
