Abstract
The CLEO II detector at the e e storage ring CESR has been used to search for two-photon production of the f (2220) decaying into π π . No evidence for a signal is found in 4.77fb of data and a 95% C.L. upper limit on [τ B ] (2220) of 2.5 eV is set. If this result is combined with the BES Collaboration's measurement of f (2220)→π π in radiative J/Ψ decay and the recent CLEO result for [τ BK K ] (2220), a 95% C.L. lower limit on the stickiness of 102 is obtained. This result for the stickiness provides further support for a substantial neutral parton content in the f (2220). © 1998 The American Physical Society. + + − −1 + − + − 0 0 − J γγ π π f J J γγ S S f J J
