Remark About Scaling Limit of ABJ Theory
نویسنده
چکیده
We generalize the suggestion presented in arXiv:0806.3498 that the 3d N = 8 superconformal SU(N) Chern-Simons-matter theory of Lorentzian Bagger-LambertGustavson type (L-BLG) can be obtained through the scaling limit from N = 6 superconformal U(N) × U(N) Chern-Simons-matter theory of Aharony, Bergman, Jafferis and Maldacena (ABJM) to the case when we study the scaling limit of N = 6 superconformal U(M)× U(N) Chern-Simons-matter theory of Aharony, Bergman and Jafferis (ABJ). We show that if we extend the ABJ theory in the same way as in arXiv:0811.1540 we can define a consistent limit that leads to SU(N) L-BLG theory together with U(M − N)k Chern-Simons theory of level k.

Lattice Fermions and the Chiral Anomaly
We show in the Wilson model that the contribution of the regular mass term to the four-divergence of the axial vector current in weak coupling perturbation theory is not zero in the chiral limit and precisely is the axial anomaly. Explicit breaking of chiral symmetry in the Wilson term is not relevant for the result. The ABJ anomaly is generated by the fermion mass term also with a chirally sym...
متن کاملIdentification of bulk coupling constant in higher spin/ABJ correspondence
We study the conjectured duality between the N = 6 Vasiliev higher spin theory on AdS4 and 3d N = 6 superconformal Chern-Simons matter theory known as the ABJ theory. We discuss how the parameters in the ABJ theory should be related to the bulk coupling constant in the Vasiliev theory. For this purpose, we compute two-point function of stress tensor in the ABJ theory by using supersymmmetry loc...
متن کاملFermion Decoupling and the Axial Anomaly on the Lattice
Wilson fermions break chiral symmetry explicitly. Explicit breaking of chiral symmetry is necessary to generate, from the lattice regulated model, the U(1) axial anomaly in the continuum limit for a vectorlike gauge theory [1]. To examine the role of the underlying lattice fermion model in generating the ABJ anomaly a convenient and transparent starting point is the condition, in this context, ...
متن کاملThe axial anomaly in lattice QED . A universal point of view
We give a perturbative proof that U(1) lattice gauge theories generate the axial anomaly in the continuum limit under very general conditions on the lattice Dirac operator. These conditions are locality, gauge covariance and the absense of species doubling. They hold for Wilson fermions as well as for realizations of the Dirac operator that satisfy the Ginsparg-Wilson relation. The proof is bas...
متن کاملAxial anomaly of QED in a strong magnetic field and noncommutative anomaly
The Adler-Bell-Jackiw (ABJ) anomaly of a 3 + 1 dimensional QED is calculated in the presence of a strong magnetic field. It is shown that in the regime with the lowest Landau level (LLL) dominance a dimensional reduction from D = 4 to D = 2 dimensions occurs in the longitudinal sector of the low energy effective field theory. In the chiral limit, the resulting anomaly is therefore comparable wi...
