Gauge theories on the κ - Minkowski spacetime

چکیده
This study of gauge field theories on κ-deformed Minkowski spacetime extends previous work on field theories on this example of a noncommutative spacetime. We construct deformed gauge theories for arbitrary compact Lie groups using the concept of enveloping algebra-valued gauge transformations and the SeibergWitten formalism. Derivative-valued gauge fields lead to field strength tensors as the sum of curvatureand torsion-like terms. We construct the Lagrangians explicitly to first order in the deformation parameter. This is the first example of a gauge theory that possesses a deformed Lorentz covariance. eMail: dmarija; meyerf; lmoeller; [email protected]

Some considerations on duality concerning kappa-Minkowski spacetime theories
In this paper we have analyzed the κ-deformed Minkowski spacetime through the light of the interference phenomena in QFT where two opposite chiral fields are put together in the same multiplet and its consequences are discussed. The chiral models analyzed here are the chiral Schwinger model, its generalized version and its gauge invariant version, where a Wess-Zumino term were added. We will se...
متن کاملκ-Minkowski Spacetimes and DSR Algebras: Fresh Look and Old Problems
Some classes of Deformed Special Relativity (DSR) theories are reconsidered within the Hopf algebraic formulation. For this purpose we shall explore a minimal framework of deformed Weyl–Heisenberg algebras provided by a smash product construction of DSR algebra. It is proved that this DSR algebra, which uniquely unifies κ-Minkowski spacetime coordinates with Poincaré generators, can be obtained...
متن کاملEffective Framework of κ-Minkowski Spacetime and Its Application
An effective Minkowski spacetime having no deformation in formal is established by introducing a well-defined proper time from the κ-deformed Minkowski spacetime related to the standard basis. The κ-Minkowski spacetime connects with a special curved spacetime through this effective spacetime. In the framework of such an effective Minkowski spacetime as a mapped coordinate system of the κ-deform...

In this paper we have provided the " Missing Link " between κ-Minkowski spacetime and Doubly Special Relativity (DSR). We have constructed a relativistic point particle Lagrangian that has the κ-Minkowski algebra as its symplectic structure and has the DSR dispersion relation as its energy spectrum. Thus a dynamical connection between κ-Minkowski spacetime and DSR framework has been established...

The algebra of functions on κ-Minkowski noncommutative spacetime is studied as algebra of operators on Hilbert spaces. The representations of this algebra are constructed and classified. This new approach leads to a natural construction of integration in κ-Minkowski spacetime in terms of the usual trace of operators.
