Two-loop QCD amplitudes for production at the LHC in the leading-colour approximation
Matteo Becchetti, Dhimiter Canko, Xiang Chen +7
We present a numerical computation of the two-loop QCD scattering amplitudes for the production of a top-antitop quark pair in association with a boson () at the LHC…
NNLO QCD predictions for production at the LHC
Xiang Chen
The production of a top-antitop quark pair in association with a boson () is one of the heaviest signatures currently explored at the Large Hadron Collider (LHC) and…
NNLO QCD predictions for production at hadron colliders
Matteo Becchetti, Dhimiter Canko, Xiang Chen +10
The production of a top-antitop quark pair in association with a boson constitutes one of the heaviest final states currently studied at the Large Hadron Collider (LHC) at CERN…

Analytical two-loop amplitudes of at factories
Xiang Chen, Xin Guan, Chuan-Qi He +3
In double charmonium production, a long-standing challenge is that the theoretical predictions are not consistent with the measurements at B factories. Within the NRQCD framework,…
Three-Loop QCD corrections to the production of a Higgs boson and a Jet
Xiang Chen, Xin Guan, Bernhard Mistlberger
We compute three-loop QCD corrections to the scattering amplitude of a Higgs boson and three partons interfered with its tree level counterpart. Specifically, we derive our results…
