Infrared subtleties and chiral vertices at NLO: an implicit regularization analysis

Abstract We employ implicit regularization (IReg) in quark-antiquark decays of the Z, or of a scalar (CP-even or odd) boson at NLO, and compare with dimensional schemes to reveal subtleties involving infrared divergence cancellation and $$\gamma _5$$ γ 5 -matrix issues. Besides the absence of evanes...
