Possible evidence of Q2Q 2 mesons in γγ→rho0rho0 and rho+rho- reactions
Description
Recent γγ→rho+rho- data in the 1.3--2.0-GeV region show a strong suppression as compared to γγ→rho0rho0 data in the same region which suggests an interference between an isoscalar and an exotic isotensor structure. Both the rho0rho0 and the rho+rho- data can be accounted for quantitatively in terms of the unique flavor and color-spin structures of the I = 0 and I = 2 Q2Q 2 states. The possible connection to rho0rho0 structure in J/psi radiative decay is suggested. Other 2++ Q2Q 2 candidates in hadronic collisions are briefly discussed
