Global symmetries and 't Hooft anomalies in brane tilings
Abstract
We investigate the relation between gauge theories and brane configurations described by brane tilings. We identify U(1)B (baryonic), U(1)M (mesonic), and U(1)R global symmetries in gauge theories with gauge symmetries in the brane configurations. We also show that U(1)MU(1)B2 and U(1)RU(1)B2 't Hooft anomalies are reproduced as gauge transformations of the classical brane action.
