| Abstract: | Resonance formation in two-photon collisions in the π+π-π0 final state was investigated for the a2(1320) meson and a resonance-like structure at 1750 MeV/c2. The a2(1750) meson is observed in the ρπ and f2π channels. The spin-parity parameters were determined by fitting the data to Monte Carlo predictions and found to be predominantly in the JP = 2+ helicity 2 state. The mass and total width measured are 1740 ± 10 ± 10 MeV/c2 and 290 ± 30 ± 20 MeV, respectively. The radiative width measured is 0.27 ± 0.02 ± 0.04 keV. |
