Anomaly of (2, 0) Theories

We compute gravitational and axial anomaly for D-type (2, 0) theories realized on N pairs of coincident M5-branes at R/Z2 orbifold fixed point. We first summarize work by Harvey, Minasian, and Moore on A-type (2, 0) theories, and then extend it to include the effect of orbifold fixed point. The net anomaly inflow follows when we further take into account the consistency of T /Z2 M-theory orbifold. We deduce that the worldvolume anomaly is given by NJ8 + N(2N − 1)(2N − 2)p2/24 where J8 is the anomaly polynomial of a free tensor multiplet and p2 is the second Pontryagin class associated with the normal bundle. This result is in accord with Intriligator’s conjecture. ⋆ E-mail: [email protected]
