Quantum 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 کاملBRST Reduction of the chiral Hecke Algebra
We explore the relationship between de Rham and Lie algebra cohomologies in the finite dimensional and affine settings. In particular, given a ĝκmodule that arises as the global sections of a twisted D-module on the affine flag manifold, we show how to compute its BRST reduction modulo n(K) using the de Rham cohomology of the restrictions to N(K) orbits. A similar relationship holds between the...
متن کاملUniqueness of the Freedman-Townsend Interaction Vertex For Two-Form Gauge Fields
Let B μν (a = 1, ..., N) be a system of N free two-form gauge fields, with field strengths H μνρ = 3∂[μB a νρ] and free action S0 equal to (−1/12) ∫ dx gabH a μνρH bμνρ (n ≥ 4). It is shown that in n > 4 dimensions, the only consistent local interactions that can be added to the free action are given by functions of the field strength components and their derivatives (and the Chern-Simons forms...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولEuclidean Freedman–Schwarz model
The N=4 gauged SU(2)×SU(1,1) supergravity in four-dimensional Euclidean space is obtained via a consistent dimensional reduction of the N=1, D=10 supergravity on S × AdS3. The dilaton potential in the theory is proportional to the difference of the two gauge coupling constants, which is due to the opposite signs of the curvatures of S and AdS3. As a result, the potential can be positive, negati...
