Soft Contributions Stabilize NNLO QCD Corrections to Quarkonium Production and Decay
Luca Maxia, Hua-Sheng Shao, Lukas Simon +1
Next-to-next-to-leading order (NNLO) QCD corrections to quarkonium production and decay are known to exhibit perturbative instabilities within non-relativistic QCD. We identify the…

Analytic NNLO transverse-momentum-dependent soft function for heavy quark pair hadroproduction at threshold
Hua-Sheng Shao, Guoxing Wang
The transverse-momentum-dependent (TMD) soft function for non-relativistic heavy quark pair production at hadron colliders is analytically computed at next-to-next-to-leading order…

One-loop transverse-momentum-dependent soft function at higher orders in the dimensional regulator
Hua-Sheng Shao, Guoxing Wang
The transverse-momentum-dependent (TMD) soft function for a generic hadroproduction process involving massive colored particles is analytically calculated at the one-loop level, ex…
