Two-loop matching of the chromo-magnetic dipole operator with the gradient flow
J. BorgulatR. HarlanderM. D. RizikA. Shindler
文献摘要
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.
