BRST, anti-BRST and gerbes
We discuss BRST and anti–BRST transformations for an Abelian antisymmetric gauge field in 4D and find that, in order for them to anticommute, we have to impose a condition on the auxiliary fields. This condition is similar to the Curci–Ferrari condition for the 4D non–Abelian 1-form gauge theories and represents a consistency requirement. We interpret it as a signal that our Abelian 2-form gaug...
متن کاملHamiltonian BRST-anti-BRST Theory
The hamiltonian BRST-anti-BRST theory is developed in the general case of arbitrary reducible first class systems. This is done by extending the methods of homological perturbation theory, originally based on the use of a single resolution, to the case of a biresolution. The BRST and the anti-BRST generators are shown to exist. The respective links with the ordinary BRST formulation and with th...
متن کاملQuantum BRST operators in extended BRST anti BRST formalism
The quantum BRST anti BRST operators are explicitly derived and the consequences related to correlation functions are investigated. The connection with the standard formalism and the loopwise expansions for quantum operators and anomalies in Sp(2) approach are analyzed .
متن کامل0 Renormalization of Non - locally Regularized BRST - anti - BRST theories
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 subtract the divergences as well as to calculate genuine higher loop BRST and anti BRST anomalies.
متن کاملIntegrable hierarchies from BRST-anti-BRST gauge-fixing
The BRST formulation is used in order to derive the existence criterion for classical bi-Hamiltonian systems, based on non-anomalous deformation of the gauge-fixing structure. The recursion operator is then used to provide the entire hierarchy of integrable models associated to the original BRST and anti-BRST charges.
