BRST-anti-BRST Symmetric Conversion of Second-Class Constraints [PDF]

open access: yes, 2003
A general method of the BRST--anti-BRST symmetric conversion of second-class constraints is presented. It yields a pair of commuting and nilpotent BRST-type charges that can be naturally regarded as BRST and anti-BRST ones.
