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…
Light-by-Light Scattering at Next-to-Leading Order in QCD and QED
Ajjath A H, Ekta Chaubey, Mathijs Fraaije +2
The recent experimental observation of Light-by-Light (LbL) scattering at the Large Hadron Collider has revived interest in this fundamental process, and especially of the accurate…
