abstract
We resum threshold double logarithms that appear in inclusive production of heavy quarkonium. This resolves the catastrophic failure of fixed-order perturbation theory where quarkonium cross sections at large transverse momentum can turn negative due to large radiative corrections. We find that resummation is imperative for describing measured prompt production rates of $J/\psi$ at large transverse momentum.

Next-to-next-to-leading-order QCD corrections to ${}^3S_1^{(8)}$ gluon fragmentation function for quarkonium
First NNLO QCD short-distance coefficients for the ³S₁⁽⁸⁾ gluon fragmentation function are obtained numerically to high precision, with analytic endpoint logarithms reconstructed for threshold resummation.

Impact of relativistic corrections to high-pT prompt-psi(2S) production at hadron colliders
Relativistic O(v^2) corrections to color-singlet fragmentation functions, especially for gluons, bring leading-power NRQCD predictions for prompt psi(2S) at high pT into agreement with LHC data without color-octet mat...

How well does nonrelativistic QCD factorization work at next-to-leading order?
A single set of NRQCD color-octet matrix elements fitted to LHC J/psi and eta_c data predicts a wide range of quarkonium observables, including Upsilon(3S) production and low-momentum photoproduction, with residual fa...
