Conformal Anomalies in Noncommutative Gauge Theories
نویسنده
چکیده
We calculate conformal anomalies in noncommutative gauge theories by using path integral method (Fujikawa’s method). As well as the axial anomalies and chiral gauge anomalies, the conformal anomalies take the form of the straightforward Moyal deformation in the corresponding conformal anomalies in ordinary gauge theories. However, Moyal star product leads the difference in the coefficient of the conformal anomalies between noncommutative gauge theories and ordinary gauge theories. The β(Callan-Symanzik) functions which is evaluated from the coefficient of the conformal anomalies coincide with the result of perturbative analysis. ∗E-mail address: [email protected]

The Uv and Ir Origin of Nonabelian Chiral Gauge Anomalies on Noncommutative Minkowski Space-time
We discuss both the UV and IR origin of the one-loop triangle gauge anomalies for noncommutative nonabelian chiral gauge theories with fundamental, adjoint and bi-fundamental fermions for U(N) groups. We find that gauge anomalies only come from planar triangle diagrams, the non-planar triangle contributions giving rise to no breaking of the Ward identies. Generally speaking, theories with funda...
متن کاملUV/IR Mixing and Anomalies in Noncommutative Gauge Theories
Using path integral method (Fujikawa’s method) we calculate anomalies in noncommutative gauge theories with fermions in the bi-fundamental and adjoint representation. We find that axial and chiral gauge anomalies coming from non-planar contributions are derived in the low noncommutative momentum limit p̃μ(≡ θpν) → 0. The adjoint chiral fermion carries no anomaly in non-planar sector in D = 4k(k ...
متن کاملAnomaly and Nonplanar Diagrams in Noncommutative Gauge Theories
Anomalies in relation to nonplanar triangle diagrams of noncommutative gauge theory are studied. Local chiral gauge anomaly for noncommutative U(1) and U(N) gauge theories with adjoint matter fields is determined perturbatively and shown to vanish for both planar and nonplanar diagrams. For U(1) gauge theory with fundamental matter field coupling, three different noncommutative currents are fou...
متن کاملPlanar and Nonplanar Konishi Anomalies and Exact Wilsonian Effective Superpotential for Noncommutative N = 1 Supersymmetric U ( 1 )
Abstract The Konishi anomalies for noncommutative N = 1 supersymmetric U(1) gauge theory arising from planar and nonplanar diagrams are calculated. Whereas planar Konishi anomaly is the expected ⋆-deformation of the commutative anomaly, nonplanar anomaly reflects the important features of nonplanar diagrams of noncommutative gauge theories, such as UV/IR mixing and the appearance of nonlocal op...
متن کاملNonplanar Anomalies in Noncommutative Theories and the Green-Schwarz Mechanism
We discuss nonplanar anomalies in noncommutative gauge theories. In particular we show that a nonplanar anomaly exists when the external noncommutative momentum is zero and that it leads to a non-conservation of the associated axial charge. In the case of nonplanar local anomalies, a cancellation of the anomaly can be achieved by a Green-Schwarz mechanism. In an example of D3 branes placed on a...
