  "abstract": "We study the renormalization of anomaly-free chiral $SU(N)$ gauge theories without scalar fields through two-loop order. We adopt the Breitenlohner--Maison--'t Hooft--Veltman (BMHV) scheme for the treatment of $γ_5$ in dimensional regularization. This prescription induces spurious breaking of BRST symmetry, requiring finite symmetry-restoring counter-terms in addition to the subtraction of ultraviolet divergences. We derive these counter-terms for a general, possibly reducible fermion representation, thus restoring the BRST symmetry, through two loops.",
