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 K₈K₈. We present a restrictive upper limit on the product of the two-photon partial width and the K₈K₈ branching fraction, (γ_γγB_K₈K₈)_{f_j(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.
