Gluon fragmentation to 3DJ quarkonium and test of color-octet production mechanism
Abstract
We report the recent progress in the studies of D-wave heavy quarkonia production from gluon fragmentation at the Tevatron and in Z0 decays, and the D-wave charmonia production in B decays. We show that the color-octet contributions are of crucial importance to the production of D-wave quarkonia. Signals, as strong as that for J/ and , should be seen for the D-wave charmonium in the processes. These will provide a test of the color-octet production mechanism.
