Symmetry properties of massive gauge theories in nonlinear background gauges: Background dependence of Green functions
نویسنده
چکیده
Nonabelian gauge theories with a generic background field Aμ in nonlinear gauges due to Delbourgo and Jarvis are investigated. The Aμ-dependence is completely determined by the help of a linear differential equation which obtaines from the Kluberg-Stern-Zuber and the Lee identity. Its integration leads to a relation between the one-particle irreducible vertex functional in the background field Aμ and the corresponding functional for Aμ = 0. An analogous relation holds for the generating functional of the complete Green functions which, after restriction to physical Green functions, is used to confirm a result obtained by Rouet in the case of linear background gauge.

Duality Symmetric Quantization of Superstring
A general covariant quantization of superparticle, Green-Schwarz superstring and a supermembrane with manifest supersymmetry and duality symmetry is proposed. This quantization provides a natural quantum mechanical description of curved BPStype backgrounds related to the ultra-short supersymmetry multiplets. Half-size commuting and anticommuting Killing spinors admitted by such backgrounds in q...
متن کاملThe effective action and quantum gauge transformations
The concept of symmetry was and remains a very powerful tool for construction of the quantum field theory. One of its main virtues is that the symmetry restricts a form of the action, which lies in the ground of the theory. Consequences of the classical symmetry play a crucial role for renormalizability of the quantum theory. And in the investigation of this problem the effective action takes a...
متن کاملGauge Invariance of Green Functions: Background-Field Method versus Pinch Technique
Application of the background-field method to QCD and the electroweak Standard Model yields gauge-invariant effective actions giving rise to simple Ward identities. Within this method, we calculate the quantities that have been treated in the literature using the pinch technique. Putting the quantum gauge parameter equal to one, we recover the pinch-technique results as a special case of the ba...
متن کاملosp(1,2)-covariant Lagrangian quantization of reducible massive gauge theories
The osp(1, 2)-covariant Lagrangian quantization of irreducible gauge theories [1] is generalized to L-stage reducible theories. The dependence of the generating functional of Green’s functions on the choice of gauge in the massive case is discussed and Ward identities related to osp(1, 2) symmetry are given. Massive first-stage theories with closed gauge algebra are studied in detail. The gener...

The osp(1, 2)–covariant Lagrangian quantization of irreducible gauge theories [1] is generalized to L–stage reducible theories. The dependence of the generating functional of Green’s functions on the choice of gauge in the massive case is discussed and Ward identities related to osp(1, 2) symmetry are given. Massive first–stage theories with closed gauge algebra are studied in detail. The gener...
