Two photon production of four-quark states

It is shown that the reaction γγ into hadrons is a rather effective means of searching for four-quark states. The well-known anomaly in γγ → ξ 0 ξ 0 is interpreted as the tensor four-quark resonance production. We predict the absence of similar analogous enhancement in γγ → ξ + ξ −.
