dc.description.abstract | We have searched for prompt production of χ c 1 , χ c 2 and X ( 3872 ) in continuum e + e − annihilations using a 386 fb − 1 data sample collected around √ s = 10.6 GeV with the BABAR detector using the γ J / ψ decay mode. After accounting for the feed-down from ψ ( 2 S ) → γ χ c 1 , 2 , no significant signal for prompt χ c 1 , 2 production is observed. We present improved upper limits at 90% confidence level on the production cross sections of 77 fb for χ c 1 and 79 fb for χ c 2 , for events where the χ c momentum exceeds 2.0 GeV and there are at least three additional charged tracks. These limits are consistent with NRQCD predictions. We also set an upper limit on the prompt production of X ( 3872 ) through the decay X ( 3872 ) → γ J / ψ . | - |
