Hadronic vacuum polarization using gradient flow

Hadronic vacuum polarization using gradient flow

Abstract The gradient-flow operator product expansion for QCD current correlators including operators up to mass dimension four is calculated through NNLO. This paves an alternative way for efficient lattice evaluations of hadronic vacuum polarization functions. In addition, flow-time evolution equa...
