Resumen
The decays of the ZZ boson and CP-even or CP-odd scalar bosons into quark–antiquark pairs have been calculated at NLO in the framework of Implicit Regularization (IReg), which operates strictly in the physical dimension and complies with the BPHZ procedure. The presence of the γ5γ5​ matrix is dealt without the need of gauge symmetry restoring counterterms and the Kinoshita–Lee–Nauenberg (KLN) theorem is verified. The results are compared to the ones obtained in the Dimensional Reduction scheme (DRed).
