An observation on Feynman diagrams with axial anomalous subgraphs in dimensional regularization with an anticommuting
Long Chen
Through the calculation of the matrix element of the singlet axial-current operator between the vacuum and a pair of gluons in dimensional regularization with an anticommuting $γ_5…
Top and bottom quark forward-backward asymmetries at next-to-next-to-leading order QCD in (un)polarized electron positron collisions
Werner Bernreuther, Long Chen, Peng-Cheng Lu +1
We consider, at order in the QCD coupling, top-quark pair production in the continuum at various center-of-mass energies and -quark pair production at the resonance…
Complete two-loop QCD amplitudes for production at hadron colliders
Long-Bin Chen, Liang Dong, Hai Tao Li +3
We calculate the complete two-loop QCD amplitudes for hadronic production by combining analytical and numerical techniques. The amplitudes have been first reduced to master in…
Analytic result for the top-quark width at next-to-next-to-leading order in QCD
Long-Bin Chen, Hai Tao Li, Jian Wang +1
We present the first full analytic results of next-to-next-to-leading order (NNLO) QCD corrections to the top-quark decay width by calculating the imaginary part of th…
Analytic two-loop amplitudes for production: leading color and light fermion-loop contributions
Long-Bin Chen, Liang Dong, Hai Tao Li +3
We present the analytical results of the two-loop amplitudes for hadronic production, focusing on the leading color and light fermion-loop contributions. The calculation of th…
A note on quark and gluon energy-momentum tensors
Taushif Ahmed, Long Chen, Michał Czakon
We discuss the constraints on quark and gluon energy-momentum tensors in QCD that follow from the requirement of Renormalisation-Group invariance of the traces of these operators.…
