Journal articleAlbrecht H, Ehrlichmann H, Gläser R, et al., 1991,
Observation of spin-parity 2+ dominance in the reaction γγ→ρ0ρ0 near threshold
, Zeitschrift Fur Physik C Particles and Fields, Vol: 50, Pages: 1-10, ISSN: 0170-9739The reaction γγ→π<sup>+</sup>π<sup>-</sup>π<sup>+</sup>π<sup>-</sup> has been studied with the ARGUS detector. The rate in the invariant mass region below 1.8 GeV/c<sup>2</sup> is found to be largely due to ρ<sup>0</sup>ρ<sup>0</sup> production. A spin-parity analysis shows a dominance of the partial wave (J<sup>P</sup>, J<inf>z</inf>)=(2<sup>+</sup>, 2) with a small admixture from J<sup>P</sup>=0<sup>+</sup>. The contribution of negative parity states is consistent with zero. The large ratio of cross sections σ(γγ→ρ<sup>0</sup>ρ<sup>0</sup>)/σ(γγ→ρ<sup>+</sup>ρ<sup>-</sup>)≃4, and the dominance of the J<sup>P</sup>=2<sup>+</sup> wave in the reaction γγ→ρ<sup>0</sup>ρ<sup>0</sup> is a signature consistent with the production of an exotic (I=2) resonance. © 1991 Springer-Verlag.
