Automated NRQCD and NRQED simulations of quarkonium and leptonium production with P-wave states and physical-mass effects
Luca Maxia, Hua-Sheng Shao, Lukas Simon
We present the module, which extends the $\texttt{MadGraph5_aMC@NLO}$ framework by providing a fully automated solution for the simulation of arbitrary tree-leve…
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…
FKS subtraction for quarkonium production at NLO
Ajjath A H, Hua-Sheng Shao, Lukas Simon
We extend the local infrared-divergence subtraction formalism, originally proposed by Frixione, Kunszt and Signer (FKS), to calculate short-distance (differential) cross section fo…
Two-loop massive QCD and QED helicity amplitudes for light-by-light scattering
Ajjath A H, Ekta Chaubey, Hua-Sheng Shao
We present the analytic and compact two-loop helicity amplitudes for QCD and QED corrections to the light-by-light scattering process with massive internal fermions. We express the…
