Abstract: This study of U(1) gauge field theory on the kappa-deformed Minkowski spacetime extends previous work on gauge field theories on this type of noncommutative spacetime. We discuss in detail the properties of the Seiberg-Witten map and the resulting effective action for U(1) gauge theory with fermionic matter expanded in ordinary fields. We construct the conserved gauge current, fix part of the ambiguities in the Seiberg-Witten map and obtain an effective U(1) action invariant under the action of the undeformed Poincaré group.

Title:

D-deformed Wess-Zumino model and its renormalizability properties

Author:

Description:

Using the methods developed in earlier papers we analyze a new type of deformation of the superspace. The twist we use to deform the N = 1 SUSY Hopf algebra is non-hermitian and is given in terms of the covariant derivatives Dα. A SUSY invariant deformation of the Wess-Zumino action is constructed and compared with results already known in the l...

A SUSY invariant deformation of the Wess-Zumino action is constructed and compared with results already known in the literature. Finally, by calculating divergences of the two-point Green functions a preliminary analysis of renormalizability properties of the constructed model is done. As expected, there is no renormalization of mass and no tadpole diagrams appear. Keywords: supersymmetry, non-hermitian twist, deformed Wess-Zumino model, renormalization Minimize

The algebra of diffeomorphisms derived from general coordinate transformations on commuting coordinates is represented by differential operators on noncommutative spaces. The algebra remains unchanged, the comultiplication however is deformed, that way we have found a deformed bialgebra of diffeomorphisms. Scalar, vector and tensor fields are defined with appropriate transformation laws under the deformed algebra and a differential calculus is developed. For pedagogical reasons the formalism is developed for the θ-deformed space as it is the best known example of deformed spaces.

July 2001 Quantum corrections for BTZ black hole via 2D reduced model

Author:

Description:

The one-loop quantum corrections for BTZ black hole are considered using the dimensionally reduced 2D model. Cases of 3D minimal and conformal coupling are analyzed. Two cases are considered: minimally coupled and conformally coupled 3D scalar matter. In the minimal case, the Hartle-Hawking and Unruh vacuum states are defined and the correspondi...

The one-loop quantum corrections for BTZ black hole are considered using the dimensionally reduced 2D model. Cases of 3D minimal and conformal coupling are analyzed. Two cases are considered: minimally coupled and conformally coupled 3D scalar matter. In the minimal case, the Hartle-Hawking and Unruh vacuum states are defined and the corresponding semiclassical corrections of the geometry are found. The calculations are done for the conformal case too, in order to make the comparison with the exact results obtained previously in the special case of spinless black hole. Beside that we find exact corrections for AdS2 black hole for 2D minimally coupled scalar field in the Hatrle-Hawking and Boulware state. Minimize

Twisted Gauge Theories

Author:

Description:

Gauge theories on a space-time that is deformed by the Moyal-Weyl product are constructed by twisting the coproduct for gauge transformations. This way a deformed Leibniz rule is obtained, which is used to construct gauge invariant quantities. The connection will be enveloping algebra valued in a particular representation of the Lie algebra. Thi...

Gauge theories on a space-time that is deformed by the Moyal-Weyl product are constructed by twisting the coproduct for gauge transformations. This way a deformed Leibniz rule is obtained, which is used to construct gauge invariant quantities. The connection will be enveloping algebra valued in a particular representation of the Lie algebra. This gives rise to additional fields, which couple only weakly via the deformation parameter θ and reduce in the commutative limit to free fields. Consistent field equations that lead to conservation laws are derived and some properties of such theories are discussed. Minimize

Dynamical noncommutativity and Noether theorem in twisted φ ⋆4 theory

Author:

Description:

A ⋆-product is defined via a set of commuting vector fields Xa = e µ a (x)∂µ, and used in a φ⋆4 theory coupled to the e µ a (x) fields. The ⋆-product is dynamical, and the vacuum solution φ = 0, e µ a = δ µ a reproduces the usual Moyal product. The action is invariant under rigid translations and Lorentz rotations, and the conserved energy-momen...

Abstract: We discuss a deformation of the Hopf algebra of supersymmetry (SUSY) transformations based on the special choice of twist. As usual, algebra itself remains unchanged, but the comultiplication changes. This leads to the deformed Leibniz rule for SUSY transformations. Superfields are elements of the algebra of functions of the usual supercoordinates. Elements of this algebra are multiplied by using the ⋆-product which is noncommutative, hermitian and finite when expanded in power series of the deformation parameter. Chiral fields are no longer a subalgebra of the algebra of superfields. One possible deformation of the Wess-Zumino action is proposed and analyzed in detail. Differently from most of the literature concerning this subject, we work in Minkowski space-time. Keywords: supersymmetry, twist, non(anti)commutative space, deformed Wess-Zumino model.
