Anomalous U(1)s, Chern-Simons couplings and the Standard Model
نویسنده
چکیده
This proceeding is based on hep-th/0605225 and it shows that the most general anomaly related effective action contains Stückelberg, axionic and Chern-Simonslike couplings. Such couplings are generically non-trivial in orientifold string vacua. A similar analysis in quantum field theories provides similar couplings. These ChernSimons couplings generate new signals which might be visible at LHC. [email protected]

Anomalies , Anomalous U ( 1 ) ’ s and generalized Chern - Simons terms
A detailed analysis of anomalous U(1)'s and their effective couplings is performed both in field theory and string theory. It is motivated by the possible relevance of such couplings in particle physics, as well as a potential signal distinguishing string theory from other UV options. The most general anomaly related effective action is analyzed and parameterized. It contains Stückelberg, axion...
متن کاملOn Anomalies in Orbifold Theories
We study the issue of gauge invariance in five-dimensional theories compactified on an orbifold S/(Z2×Z2) in the presence of an external U(1) gauge field. From the fourdimensional point of view the theory contains a tower of Kaluza-Klein Dirac fermions with chiral couplings and it looks anomalous at the quantum level. We show that this “anomaly” is cancelled by a topological Chern-Simons term w...
متن کاملN=2–Maxwell-Chern-Simons model with anomalous magnetic moment coupling via dimensional reduction
An N=1–supersymmetric version of the Cremmer-Scherk-Kalb-Ramond model with non-minimal coupling to matter is built up both in terms of superfields and in a component-field formalism. By adopting a dimensional reduction procedure, the N=2–D=3 counterpart of the model comes out, with two main features: a genuine (diagonal) Chern-Simons term and an anomalous magnetic moment coupling between matter...
متن کاملN = 2 Solutions of Massive Type Iia and Their Chern-simons Duals
We find explicit AdS4 solutions of massive type IIA with N = 2 supersymmetry obtained deforming with a Roman mass the type IIA supersymmetric reduction of the M theory background AdS4 ×M111. The family of solutions have SU(3) × SU(3) structure and isometry SU(3) × U(1)2. They are conjectured to be dual to three-dimensional N = 2 Chern-Simons theories with generic Chern-Simons couplings and gaug...
متن کاملImplications of String Constraints for Exotic Matter and Z ′ s Beyond the Standard Model
Global consistency of string compactifications places constraints on the chiral matter spectrum of a gauge theory which include those necessary for the absence of cubic nonabelian anomalies, but also contain some additional conditions. In the class of theories we study, some of these are present in a field theory augmented by anomalous U(1)’s and Chern-Simons terms, but some are genuinely not p...
