’t Hooft Anomaly Matching Conditions for Generalized Symmetries in 2D
نویسنده
چکیده
The ’t Hooft anomaly matching conditions are a standard tool to study and test nonperturbative issues in quantum field theory. We give a new, simple proof of the anomaly matching conditions in 2D Poincarè invariant theories. We consider the case of invariance under a large class of generalized symmetries, which include abelian and non-abelian internal symmetries, space-time symmetries generated by the stress tensor, and W -type of symmetries generated by higher spin currents.

’t HOOFT ANOMALY MATCHING FOR DISCRETE SYMMETRIES
We show how to extend the ’t Hooft anomaly matching conditions to discrete symmetries. We check these discrete anomaly matching conditions on several proposed low-energy spectra of certain strongly interacting gauge theories. The excluded examples include the proposed chirally symmetric vacuum of pure N = 1 supersymmetric Yang-Mills theories, certain nonsupersymmetric confining theories and som...
متن کامل‘t Hooft Anomaly Matching for QCD
I present a set of theories which display non-trivial ‘t Hooft anomaly matching for QCD with F flavors. The matching theories are non-Abelian gauge theories with “dual” quarks and baryons, rather than the purely confining theories of baryons that ‘t Hooft originally searched for. The matching gauge groups are required to have an F ± 6 dimensional representation. Such a correspondence is reminis...

متن کامل(non)decoupling of mirror fermions
We study ’t Hooft anomaly matching in lattice models with strong Yukawa or multi-fermion interactions. Strong non-gauge interactions among the mirror fermions in a vectorlike lattice gauge theory are introduced with the aim to obtain, in a strong-coupling symmetric phase, a long-distance unbroken gauge theory with chiral fermions in a complex representation. We show how to use exact lattice chi...
متن کاملAnomalies of discrete symmetries in three dimensions and group cohomology
We study ’t Hooft anomalies for a global discrete internal symmetry G. We construct examples of bosonic field theories in three dimensions with a nonvanishing ’t Hooft anomaly for a discrete global symmetry. We also construct field theories in three dimensions with a global discrete internal symmetry G1 × G2 such that gauging G1 necessarily breaks G2 and vice versa. This is analogous to the Adl...
