In this jet-mass scheme the quark-mass anomalous dimension is completely determined by the cusp anomalous dimension at any order in perturbation theory. 2. The heavy quark jet function WebFor the quark jet function, results were known up to the two-loop level for some time (see [11–13]), and the re-sults at three loops were computed recently in [3]. On the other hand, only one- [14] and two-loop [15] results are known for the gluon jet function. Precise measure-ments of various observables at high-energy experiments
