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 (2220) in its decay to K K . We present a restrictive upper limit on the product of the two-photon partial width and the K K branching fraction, (γ B ) . 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 (2220) has substantial glueball content. © 1997 The American Physical Society. + − j 8 8 8 8 γγ K 8 K 8 f j(2220) j
