Resonance formation in the π<sup>+</sup> π<sup>-</sup> π<sup>0</sup> final state in two-photon collisions
A study of resonance formation is presented in the π<sup>+</sup> π<sup>-</sup> π<sup>0</sup> final state in two-photon collisions at LEP. The a<sub>2</sub>(1320) radiative width is measured to be Γγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production...

| Sumario: | A study of resonance formation is presented in the π<sup>+</sup> π<sup>-</sup> π<sup>0</sup> final state in two-photon collisions at LEP. The a<sub>2</sub>(1320) radiative width is measured to be Γγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production is dominant. Exclusive π<sup>+</sup> π<sup>-</sup> π<sup>0</sup> production has also been studied in the mass region above the a<sub>2</sub> in the pπ and f<sub>2</sub>π channels. This region is dominated by a J<sup>P</sup> = 2<sup>+</sup> helicity 2 wave. |
