Search for fJ(2220) in radiative J/ψ decays
2010
We present a search for f_(J)(2220) production in radiative J/ψ→γf_(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/ψ→γf_(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.
