Contribution

It introduces a novel extension of non-local regularization in the Sp(2) BRST formalism for better anomaly and divergence management.

Findings

Systematic treatment of anomalous quantum master equations

Ability to subtract divergences effectively

Calculation of higher loop BRST and anti-BRST anomalies

Abstract

An extension of the non-local regularization scheme is formulated in the Sp(2) symmetric Lagrangian BRST quantization framework. It generates a systematic treatment of the anomalous quantum master equations and allows to substract the divergences as well as to calculate genuine higher loop BRST and anti-BRST anomalies.
