Abstract

We present results of an analysis of the reaction γγ→ωρ{variant} in the two-photon process e⁺e^-→ε{lunate}⁺e^-2π⁺2π^-π⁰ in the untagged mode. The cross section is largely compatible with previous determinations; however, we do not confirm the enhancement claimed at 1.9 GeV. All observed ω's are accompanied by ρ{variant}'s in the recoiling ππ spectrum. An angular correlation analysis shows that the data is not dominated by a single spin-parity state, thus establishing severe constraints on qqqq models which predict J^P = 2⁺.
