Abstract

We use the CLEO detector at the Cornell e⁺e^- storage ring, CESR, to search for the two-photon production of the glueball candidate f_J (2220) in its decay to K_sK_s. We present a restrictive upper limit on the product of the two-photon partial width and the K_sK_s branching fraction, (Γ_γγ B_KsKs)_fJ(2220). We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f_J(2220) has substantial glueball content.
