Higher-order relativistic corrections to gluon fragmentation into spin-triplet S-wave quarkonium

open access: yes, 2012
We compute the relative-order-v^4 contribution to gluon fragmentation into quarkonium in the 3S1 color-singlet channel, using the nonrelativistic QCD (NRQCD) factorization approach. The QCD fragmentation process contains infrared divergences that produce

FKS subtraction for quarkonium production at NLO

open access: yesJournal of High Energy Physics
We extend the local infrared-divergence subtraction formalism, originally proposed by Frixione, Kunszt and Signer (FKS), to calculate short-distance (differential) cross section for any inclusive process involving a quarkonium particle in non ...

Chromoelectric fields and quarkonium-hadron interactions at high energies

open access: yes, 2005
We develop a simple model to study the heavy quarkonium-hadron cross section in the high energy limit. The hadron is represented by an external electric color field (capacitor) and the heavy quarkonium is represented by a small color dipole.
