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