Two-loop matching of the chromo-magnetic dipole operator with the gradient flow
Published 19 Dec 2022 in hep-lat and hep-ph | (2212.09824v1)
Abstract: The chromo-magnetic dipole operator is expressed in terms of operators at finite flow time in the gradient-flow formalism. The matching coefficients are evaluated through next-to-next-to-leading order QCD.
