Abstract

We have searched for prompt production of chi(c1), chi(c2) and X(3872) in continuum e(+) e(-) annihilation using a 386 fb(-1) data sample collected around root s = 10.6 GeV with the BABAR detector using the gamma J/psi decay mode. After accounting for the feed-down from psi( 2S) -> gamma chi(c1,2), no significant signal for prompt chi(c1),(2) production is observed. We present improved upper limits at 90% confidence level on the production cross sections of 77 fb for chi(c1) and 79 fb for chi(c2), for events where the chi(c) momentum exceeds 2.0 GeVand 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) -> gamma J/psi.
