Limit on the Two-Photon Production of the Glueball CandidatefJ(2220)at the Cornell Electron Storage Ring

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 fJ(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, (γγγBKsKs)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 fJ(2220) has substantial glueball content.
