ABJM type theories
In this paper we construct the N = 6 conformal supergravity in three dimensions from a set of Chern-Simons-like terms one for each of the graviton, gravitino, and R-symmetry gauge field and then couple this theory to the N = 6 superconformal ABJM theory. In a first step part of the coupled Lagrangian for this topologically gauged ABJM theory is derived by demanding that all terms of third and s...
متن کاملAlgebraic orbifold conformal field theories.
The unitary rational orbifold conformal field theories in the algebraic quantum field theory and subfactor theory framework are formulated. Under general conditions, it is shown that the orbifold of a given unitary rational conformal field theory generates a unitary modular category. Many new unitary modular categories are obtained. It is also shown that the irreducible representations of orbif...
متن کاملAnomalies in orbifold field theories
We study the constraints on models with extra dimensions arising from local anomaly cancellation. We consider a five-dimensional field theory with a U(1) gauge field and a charged fermion, compactified on the orbifold S/(Z2 × Z2). We show that, even if the orbifold projections remove both fermionic zero modes, there are gauge anomalies localized at the fixed points. Anomalies naively cancel aft...
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 کاملHow to put the Bagger-Lambert theory on an orbifold : A derivation of the ABJM model
We consider taking an orbifold of the multiple M2-brane theory recently proposed by Bagger and Lambert. Starting from the large-n limit of the 3-algebra structure realized as volume-preserving diffeomorphims, we suggest a prescription to impose an orbifold condition on various fields. As a relatively simple but non-trivial example we study an abelian orbifold C/Zk, and illustrate how one can de...
