Abstract: We present analytical five-loop results for the quark mass and quark field anomalous dimensions, for a general gauge group and in the M S ¯ $$ \overline{\mathrm{MS}} $$ 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- N f studies.
