BRST-Invariant Algebra of Constraints in Terms of Commutators and Quantum Antibrackets
I. A. Batalin, I. V. Tyutin
Abstract:
We establish the general structure of the BRST-invariant algebra of constraints in its commutator and antibracket forms via the formulation of algebra-generating equations in a supplementally extended phase space. New ghost-type variables behave as fields and antifields with respect to quantum antibrackets. The explicit form of the BRST-invariant gauge algebra is given in detail for rank-one theories with a Weyl and a Wick-ordered ghost sector. We construct a ixed-gauge unitarizing Hamiltonian and show that the formalism is physically equivalent to the standard BRST–BFV approach.
Keywords:
BRST symmetry, algebra of constraints, quantum antibracket.
