GLUON FRAGMENTATION TO D-3(J) QUARKONIA

We present a calculation of the leading order QCD fragmentation functi ons for gluons to split into spin-triplet D-wave quarkonia. We apply t hem to evaluate the gluon fragmentation contributions to inclusive D-3 (J) quarkonium production at large transverse momentum processes such as the Fermilab Tevatron and find that the D-wave quarkonia, especiall y the charmonium 2(--) state, could be observed through the color-octe t mechanism with present luminosity. Since there are distinctively lar ge gaps between the contributions of two different (i.e., color-single t and color-octet) quarkonium production mechanisms, our results may s tand as a unique test of the NRQCD color-octet quarkonium production m echanism.
