Resummation of threshold double logarithms in gluon fragmentation into quarkonia
Hee Sok Chung
I investigate the threshold double logarithmic behavior of the fragmentation function of a gluon into quarkonia, which is suppressed by in Mellin space. While…
Resummation of threshold double logarithms in quarkonium fragmentation functions
Hee Sok Chung, U-Rae Kim, Jungil Lee
We develop a formalism for resumming threshold double logarithms that appear in fragmentation functions for production of heavy quarkonia. Threshold singularities appear in fixed-o…
Resummation of threshold double logarithms in inclusive production of heavy quarkonium
Hee Sok Chung, U-Rae Kim, Jungil Lee
We resum threshold double logarithms in inclusive production of heavy quarkonium that arise from singularities near the boundary of phase space. This resolves the catastrophic fail…
Resummation of threshold double logarithms in hadroproduction of heavy quarkonium
Hee Sok Chung, U-Rae Kim, Jungil Lee
We resum threshold double logarithms that appear in inclusive production of heavy quarkonium. This resolves the catastrophic failure of fixed-order perturbation theory where quarko…
Color-octet nonrelativistic QCD matrix elements for heavy quarkonium decays in the refined Gribov-Zwanziger theory
Hee Sok Chung
We determine color-octet nonrelativistic QCD matrix elements for quarkonium decays from moments of the two-point correlation function of the QCD field-strength tensor computed in t…
Resummation and renormalization of kinematical effects in inclusive -wave quarkonium production
Hee Sok Chung
We investigate the renormalization properties of the shape function formalism for inclusive production of -wave heavy quarkonia, which arises from resumming a class of correctio…
