Exact results for Z m OS $$ {Z}_m^{\mathrm{OS}} $$ and Z 2 OS $$ {Z}_2^{\mathrm{OS}} $$ with two mass scales and up to three loops
Abstract We consider the on-shell mass and wave function renormalization constants Z m OS $$ {Z}_m^{\mathrm{OS}} $$ and Z 2 OS $$ {Z}_2^{\mathrm{OS}} $$ up to three-loop order allowing for a second non-zero quark mass. We obtain analytic results in terms of harmonic polylogarithms and iterated integ...
