Symmetries and observables for BF – theories in superspace
نویسنده
چکیده
The supersymmetric version of a topological quantum field theory describing flat connections, the super BF-theory, is studied in the superspace formalism. A set of observables related to topological invariants is derived from the curvature of the superspace. Analogously to the non-supersymmetric versions, we find that the theory exhibits a vector-like supersymmetry. The role of the vector supersymmetry and an additional new symmetry of the action in the construction of observables is explained.

Supersymmetric Wilson Loops, Superstring-like Observables, and the Natural Coupling of Superstrings To Supersymmetric Gauge Theories
We obtain an explicit expression for the supersymmetric Wilson loop in terms of chiral superfields and supercurrents in superspace. The result turns out to be different from what one would expects from the simple replacement of Lie algebraic valued connection in the exponent with the corresponding super-Lie algebraic one. In the abelian supersymmetric gauge theories, generalizing the super-part...
متن کاملDressing Symmetries of Holomorphic BF Theories ∗
We consider holomorphic BF theories, their solutions and symmetries. The equivalence ofČech and Dolbeault descriptions of holomorphic bundles is used to develop a method for calculating hidden (nonlocal) symmetries of holomorphic BF theories. A special cohomological symmetry group and its action on the solution space are described.

The absence of fermion kinetic terms in supersymmetric-BF gauge theories is established. We do this by means of explicit off-shell (superspace) constructions. As part of our study we give the superspace constraints for D=3, N=4 super Yang-Mills along with the D=3, N=4 superconformal algebra. The puzzle we are interested in solving is the fact that the topological cousins, known as super-BF gaug...
متن کاملOn Symmetries of Chern-Simons and BF Topological Theories
We describe constructing solutions of the field equations of Chern-Simons and topological BF theories in terms of deformation theory of locally constant (flat) bundles. Maps of flat connections into one another (dressing transformations) are considered. A method of calculating (nonlocal) dressing symmetries in Chern-Simons and topological BF theories is formulated.
متن کاملSuperspace interpretation of mass–dependent BRST symmetries in general gauge theories
A superspace formulation is proposed for the osp(1, 2)–covariant Lagrangian quantization of general massive gauge theories. Thereby, osp(1, 2) is considered as subalgebra of the superalgebra sl(1, 2) which is interpreted as conformal algebra acting on two anticommuting coordinates. The mass–dependent (anti)BRST symmetries of the quantum action in the osp(1,2) superfield formalism are realized a...
