Renormalization of the axial current operator in dimensional regularization at four-loop in QCD

Renormalization of the axial current operator in dimensional regularization at four-loop in QCD

Abstract 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 the off-shell Ward-Takahashi identity for an axial current with a non-anticommuting γ 5. A possible applicati...
