Description

The structure observed in the reaction γγ -> rho0rho0 is interpreted as due to 2++ (I = 0,2) Q2anti Q2 states with a background contribution from 0++ (I = 0,2) Q2anti Q2 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 Q2anti Q2 mesons in hadron scattering processes and J/psi radiative decay are discussed briefly.
