Observables in Topological Theories: A Superspace Formulation
J. L. Boldo, C. P. Constantinidis, F. Gieres +2
Observables of topological Yang-Mills theory were defined by Witten as the classes of an equivariant cohomology. We propose to define them alternatively as the BRST cohomology clas…
Symmetries and observables in topological gravity
C. P. Constantinidis, A. Deandrea, F. Gieres +2
After a brief review of topological gravity, we present a superspace approach to this theory. This formulation allows us to recover in a natural manner various known results and to…
Five-Dimensional BF Theory and Four-Dimensional Current Algebra
S. Emery, H. Jirari, O. Piguet
We consider the relation between the five-dimensional BF model and a four-dimensional local current algebra from the point of view of perturbative local quantum field theory. We us…
A Renormalized Supersymmetry in the Topological Yang-Mills Field Theory
A. Brandhuber, O. Moritsch, M. W. de Oliveira +2
We reconsider the algebraic BRS renormalization of Witten's topological Yang-Mills field theory by making use of a vector supersymmetry Ward identity which improves the finiteness…
Adler-Bardeen theorem and vanishing of the gauge beta function
O. Piguet, S. P. Sorella
The proof of the non-renormalization theorem for the gauge anomaly of four-dimensional theories is extended to the case of models with a vanishing one-loop gauge beta function.
A short comment on the supersymmetric structure of Chern-Simons theory in the axial gauge
A. Brandhuber, M. Langer, M. Schweda +2
The topological supersymmetry of the pure Chern-Simons model in three dimensions is established in the case where the theory is defined in the axial gauge.
