Vector Supersymmetry and Finite Quantum Correction of Chern-Simons Theory in the Light-Cone Gauge
نویسنده
چکیده
Vector supersymmetry is shown to exist also in light-cone gauge ChernSimons theory. Using a gauge invariant regularization scheme, we demonstrate explicitly that the finite quantum correction to the coupling constant of Chern-Simons theory is intimately associated with the breaking of vector supersymmetry at the regularization level. The advantage of investigating such a quantum phenomenon in the light-cone gauge is emphasized and the BRST and vector supersymmetry invariance of quantum effective action is discussed.

Inconsistency of Naive Dimensional Regularizations and Quantum Correction to Non-Abelian Chern-Simons-Matter Theory Revisited
We find the inconsistency of dimensional reduction and naive dimensional regularization in their applications to Chern-Simons type gauge theories. Further we adopt a consistent dimensional regularization to investigate the quantum correction to non-Abelian Chern-Simons term coupled with fermionic matter. Contrary to previous results, we find that not only the Chern-Simons coefficient receives q...
متن کاملThe Chern-Simons Coefficient in Supersymmetric Non-Abelian Chern-Simons Higgs Theories
By taking into account the effect of the would be Chern-Simons term, we calculate the quantum correction to the Chern-Simons coefficient in supersymmetric Chern-Simons Higgs theories with matter fields in the fundamental representation of SU(n). Because of supersymmetry, the corrections in the symmetric and Higgs phases are identical. In particular, the correction is vanishing for N = 3 supersy...
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...
متن کاملInterpolating gauge fixing for Chern-Simons theory
Chern-Simons theory is analyzed with a gauge-fixing which allows to discuss the Landau gauge and the light-cone gauge at the same time.
