Possible evidence of Q2Q2 mesons in 00 and +- reactions

Recent +- data in the 1.3-2.0-GeV region show a strong suppression as compared to 00 data in the same region which suggests an interference between an isoscalar and an exotic isotensor structure. Both the 00 and the +- data can be accounted for quantitatively in terms of the unique flavor and color-spin structures of the I=0 and I=2 Q2Q2 states. The possible connection to 00 structure in J radiative decay is suggested. Other 2++ Q2Q2 candidates in hadronic collisions are briefly discussed.
