One-loop Shift in Noncommutative Chern-Simons Coupling
نویسندگان
چکیده
In this paper we study the one-loop shift in the coupling constant in a noncommutative pureU(N) Chern-Simons gauge theory in three dimensions. The one-loop shift is shown to be a constant proportional to N , independent of noncommutativity parameters, and non-vanishing for U(1) theory. Possible physical and mathematical implications of this result are discussed.

Operator Regularization and Noncommutative Chern Simons Theory
1 Abstract We examine noncommutative Chern Simons theory using operator regularization. Both the ζ-function and the η-function are needed to determine one loop effects. The contributions to these functions coming from the two point function is evaluated. The U(N) noncommu-tative model smoothly reduces to the SU(N) commutative model as the noncommutative parameter θ µν vanishes. 1 2 Introduction...
متن کاملNoncommutativity in Maxwell-chern-simons-matter Theory Simulates Pauli Magnetic Coupling
We study interactions between like charges in the noncommutative Maxwell-Chern-Simons electrodynamics minimally coupled to spinors or scalars. We demonstrate that the non-relativistic potential profiles, for only spatial noncommutativity, are nearly identical to the ones generated by a non-minimal Pauli magnetic coupling, originally introduced by Stern [12]. Although the Pauli term has crucial ...
متن کاملGauge invariance of the Chern-Simons action in noncommutative geometry
In complete analogy with the classical case, we define the Chern-Simons action functional in noncommutative geometry and study its properties under gauge transformations. As usual, the latter are related to the connectedness of the group of gauge transformations. We establish this result by making use of the coupling between cyclic cohomology and K-theory and prove, using an index theorem, that...
متن کاملAbsence of Higher Order Corrections to Noncommutative Chern-Simons Coupling
We analyze the structure of noncommutative pure Chern-Simons theory systematically in the axial gauge. We show that there is no IR/UV mixing in this theory in this gauge. In fact, we show, using the usual BRST identities as well as the identities following from vector supersymmetry, that this is a free theory. As a result, the tree level Chern-Simons coefficient is not renormalized. It also hol...
متن کاملPerturbative Chern - Simons Theory on Noncommutative R 3
A U(N) Chern-Simons theory on noncommutative R3 is constructed as a θ-deformed field theory. The model is characterized by two symmetries: the BRST-symmetry and the topological linear vector supersymmetry. It is shown that the theory is finite and θμν -independent at the one loop level and that the calculations respect the restriction of the topological supersymmetry. Thus the topological θ-def...
