N=2 Supergravity and Special Geometry

Antoine Van Proeyen

The essential elements in the construction of the couplings of vector multiplets to supergravity using the conformal approach are repeated. This approach leads automatically to the…

Target Space Supersymmetric Sigma Model Calculations

Jan de Boer, Kostas Skenderis

We briefly review the covariant formulation of the Green-Schwarz superstring by Berkovits, and describe how a detailed tree-level and one-loop analysis of this model leads, for the…

Local BRST cohomology in minimal D=4, N=1 supergravity

Friedemann Brandt

The local BRST cohomology is computed in old and new minimal supergravity, including the coupling to Yang-Mills gauge multiplets. This covers the determination of all gauge invaria…

Higher Loop Anomalies and their Consistency Conditions in Nonlocal Regularization

Jordi París, Walter Troost

An algebraic program of computation and characterization of higher loop BRST anomalies is presented. We propose a procedure for disentangling a genuine{\it local} higher loop anoma…

Global Symmetries in the Antifield-Formalism

Friedemann Brandt, Marc Henneaux, André Wilch

In this paper, two things are done. (i) First, it is shown that any global symmetry of a gauge-invariant theory can be extended to the ghosts and the antifields so as to leave inva…

The Definitions of Special Geometry

Ben Craps, Frederik Roose, Walter Troost +1

The scalars in vector multiplets of N=2 supersymmetric theories in 4 dimensions exhibit `special Kaehler geometry', related to duality symmetries, due to their coupling to the vect…

Projection Operator Approach to Constrained Systems

Jan Govaerts

Recently, within the context of the phase space coherent state path integral quantisation of constrained systems, John Klauder introduced a reproducing kernel for gauge invariant p…

On the determination of anomalies in supersymmetric theories

Friedemann Brandt, Jordi París

We develop an efficient technique to compute anomalies in supersymmetric theories by combining the so-called nonlocal regularization method and superspace techniques. To illustrate…

Local BRST cohomology and covariance

Friedemann Brandt

The paper provides a framework for a systematic analysis of the local BRST cohomology in a large class of gauge theories. The approach is based on the cohomology of s+d in the jet…

The BPHZ renormalised BV master equation and Two-loop Anomalies in Chiral Gravities

Frank De Jonghe, Jordi Paris, Walter Troost

Anomalies and BRST invariance are governed, in the context of Lagrangian Batalin-Vilkovisky quantization, by the master equation, whose classical limit is . Using Zimmerm…
