Abstract

The structure observed in the reaction γγ→ρ{variant}⁰ρ{variant}⁰ is interpreted as due to 2⁺⁺ (I=0, 2) Q²Q² states with a background contribution from 0⁺⁺ (I= 0, 2) Q²Q² states. Both of these states decay predominantly via two vector mesons. The predictions of the other two vector channels are presented, and the possibilities of searching for Q²Q² mesons in hadron scattering processes and J φ{symbol} radiative decay are discussed briefly.
