Abstract

We present a search for f(J)(2220) production in radiative J/psi --> gamma f(J)(2220) decays using 460 fb(-1) of data collected with the BABAR detector at the SLAC PEP-II e(+)e(-) collider. The f(J)(2220) is searched for in the decays to K(+)K(-) and K(S)(0)K(S)(0). No evidence of this resonance is observed, and 90% confidence level upper limits on the product of the branching fractions for J/psi --> gamma f(J)(2220) and f(J)(2220) --> K(+)K(-)(K(S)(0)K(S)(0)) as a function of spin and helicity are set at the level of 10(-5), below the central values reported by the Mark III experiment.
