Ultraviolet and Infrared Finiteness in Two Dimensional Curved Space-Time
H. Zerrouki
Different models of field theories in two dimensions can be described by the action $Tr\int \vf F$. In the presence of a curved background, we construct a local supersymmetry-like…
A comment on the 4D antisymmetric tensor field model
J. Rant, M. Schweda, H. Zerrouki
We show the existence of a renormalizable local supersymmetry for the gauge fixed action of the four dimensional antisymmetric tensor field model in a curved background quantized i…
A Note on the 4D Antisymmetric Tensor Field Model in Curved Space-Time
H. Zerrouki
Using the BRS techniques, we prove the existence of a local and nonlinear symmetry of the gauge fixed action of the antisymmetric tensor field model in curved background.
Local gravitational supersymmetry of Chern-Simons theory in the vielbein formalism
S. Emery, O. Moritsch, M. Schweda +2
We discuss the Chern-Simons theory in three-dimensional curved space-time in the vielbein formalism. Due to the additional presence of the local Lorentz symmetry, beside the diffeo…
BRST cohomology of Yang-Mills gauge fields in the presence of gravity in Ashtekar variables
O. Moritsch, M. Schweda, T. Sommer +2
The BRST transformations for the Yang-Mills gauge fields in the presence of gravity described by Ashtekar variables are obtained by using the so-called Maurer-Cartan horizontality…
