Diffeomorphism Invariant Theories and Vector Supersymmetry
Olivier Piguet
Einstein gravity in the Palatini first order formalism is shown to possess a vector supersymmetry of the type encountered in the topological gauge theories. A peculiar feature of t…
Comment on ``On spin-1 massive particles coupled to a Chern-Simons field''
O. M. Del Cima, D. H. T. Franco, J. A. Helayel-Neto +1
In this comment we discuss some serious inconsistencies presented by Gomes, Malacarne and da Silva in their paper, Phys.Rev. D60 (1999) 125016 (hep-th/9908181).
Introduction to Supersymmetric Gauge Theories
Olivier Piguet
In these lectures I present a basic introduction to supersymmetry, especially to N=1 supersymmetric gauge theories and their renormalization, in the Wess-Zumino gauge. I also discu…

Symmetries of the Chern-Simons Theory in the Axial Gauge, Manifold with Boundary
S. Emery, O. Piguet
The field equations of the Chern-Simons theory quantized in the axial gauge are shown to be completely determined by supersymmetry Ward identities which express the invariance of t…
Symmetries of the Chern-Simons Theory in the Axial Gauge
A. Brandhuber, S. Emery, M. Langer +3
The Green functions of the Chern-Simons theory quantized in the axial gauge are shown to be calculable as the unique, exact solution of the Ward identities which express the invari…
