Renormalization of the axial current operator in dimensional regularization at four-loop in QCD
Long Chen, Michał Czakon
We provide the renormalization constants of the axial current operators, both singlet and non-singlet, in dimensional regularization up to four-loop order in QCD, determined using…
Renormalization of the flavor-singlet axial-vector current and its anomaly in QCD
Long Chen
The renormalization constant of the flavor-singlet axial-vector current with a non-anticommuting in dimensional regularization is determined to order in QCD wit…
Forward-backward asymmetries of the heavy quark pair production in collisions at
Long Chen
The talk is on a computational set-up for calculating the production of a massive quark-antiquark pair in electron positron collisions to order in the coupling of quantum c…
Renormalization of the flavor-singlet axial-vector current and its anomaly in dimensional regularization
Taushif Ahmed, Long Chen, Michał Czakon
The renormalization constant of the flavor-singlet axial-vector current with a non-anticommuting in dimensional regularization is determined to order in QCD wit…
The electric dipole moment of the tau lepton revisited
Werner Bernreuther, Long Chen, Otto Nachtmann
We reconsider the issue of the search for a nonzero electric dipole form factor (EDM) using optimal observables in production by collisions in the cente…
Higgs boson pair production at NLO QCD
Long-Bin Chen, Hai Tao Li, Hua-Sheng Shao +1
Understanding the Higgs potential by measuring its self-interactions is fundamental in answering several big questions, such as electroweak symmetry breaking, electroweak baryogene…
