Four-loop cusp anomalous dimension in QED

Four-loop cusp anomalous dimension in QED

Abstract The 4-loop C F 3 T F n l and 5-loop C F 4 T F n l terms in the HQET field anomalous dimension γ h are calculated analytically (the 4-loop one agrees with the recent numerical result [1]). The 4-loop C F 3 T F n l and 5-loop C F 4 T F n l terms in the cusp anomalous dimension Γ(φ) are calcul...
