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 KsKs. We present a restrictive upper limit on the product of the two-photon partial width and the KsKs branching fraction, (Gamma(gamma gamma)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.
