Gluon fragmentation to ${}^3{D}_J$ quarkonium and test of color-octet production mechanism

Kuang-Ta Chao, Cong-Feng Qiao, Feng Yuan

We report the recent progress in the studies of D-wave heavy quarkonia production from gluon fragmentation at the Tevatron and in Z^0 decays, and the D-wave charmonia production in…
