Abstract

The CLEO II detector at the

e^{+} e^{-}

storage ring CESR has been used to search for two-photon production of the

f_{J} (2220)

decaying into

π^{+} π^{-}

. No evidence for a signal is found in

4.77 {fb}^{- 1}

of data and a 95% C.L. upper limit on

[Γ_{γ γ} B_{π^{+} π^{-}}]_{f_{J} (2220)}

of 2.5 eV is set. If this result is combined with the BES Collaboration's measurement of

f_{J} (2220) \to π^{+} π^{-}

in radiative

J / ψ

decay and the recent CLEO result for

[Γ_{γ γ} B_{K_{S}^{0} K_{S}^{0}}]_{f_{J} (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_{J} (2220)
