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.
