Download Factorized Power Expansion for High-pT Heavy Quarkonium Production Book in PDF, ePub and Kindle
We show that when the factorized cross section for heavy quarkonium production includes next-to-leading power contributions associated with the production of the heavy quark pair at short distances, it naturally reproduces all high pT results calculated in nonrelativistic QCD (NRQCD) factorization. This extended formalism requires fragmentation functions for heavy quark pairs, as well as for light partons. When these fragmentation functions are themselves calculated using NRQCD, we find that two of the four leading NRQCD production channels, 3S[1]1 and 1S[8]0, are dominated by the next-to-leading power contributions for a very wide pT range. The large next-to-leading order corrections of NRQCD are absorbed into the leading order of the first power correction. The impact of this finding on heavy quarkonium production and its polarization is discussed.

Download J/[sub Psi] Production: Tevatron and Fixed-target Collisions Book in PDF, ePub and Kindle
In this talk the author shows the results of a fit of the NRQCD matrix elements to the CDF data for direct J/[psi] production, by including the radiative corrections to the g g[r-arrow][sup 3] S[sub 1][sup[1]] channel and the effect of the k[sub T]-smearing. Furthermore he performs the NLO NRQCD analysis of J/[psi] production in fixed-target proton-nucleon collisions and he fits the colour-octet matrix elements to the available experimental data. The results are compared to the Tevatron ones.
