Covariant calculation of a two-loop test of nonrelativistic QCD factorization
Geoffrey T. Bodwin, Hee Sok Chung, June-Haak Ee +2
We test the nonrelativistic QCD factorization conjecture for inclusive quarkonium production at two loops by carrying out a covariant calculation of the nonrelativistic quantum chr…

Pseudoscalar Quarkonium+gamma Production at NLL+NLO accuracy
Hee Sok Chung, June-Haak Ee, Daekyoung Kang +3
We consider the exclusive pseudoscalar heavy-quarkonium (eta_{b,c}) production in association with a photon at future lepton colliders where the collider energies of O(10^2) GeV ar…

Order-v^4 Relativistic Corrections to Gluon Fragmentation into ^3S_1 Quarkonium
Geoffrey T. Bodwin, U-Rae Kim, Jungil Lee
We compute the relativistic corrections to the color-singlet contribution to gluon fragmentation into a J/psi at relative order v^4, making use of the nonrelativistic QCD (NRQCD) f…
