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