Thomas Luthe, Andreas Maier, Peter Marquard, York Schroder
TL;DR
This paper provides new five-loop analytical calculations of quark mass and field anomalous dimensions for general gauge groups, confirming previous results for SU(3) and aligning with large-Nf studies.
Contribution
It delivers the first five-loop results for these anomalous dimensions for a general gauge group, expanding the precision of quantum chromodynamics calculations.
Findings
Confirmed known SU(3) results independently.
Aligned with large-Nf theoretical predictions.
Extended anomalous dimension calculations to five loops for general gauge groups.
Abstract
We present analytical five-loop results for the quark mass and quark field anomalous dimensions, for a general gauge group and in the MSbar scheme. We confirm the values known for the gauge group SU(3) from an independent calculation, and find full agreement with results available from large-Nf studies.
