Phys. Rev. D 69, 086003 (2004) [20 pages]The chiral anomaly from M theoryReceived 28 November 2003; published 16 April 2004 We argue that the chiral anomaly of N=1 super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on G2 holonomy manifolds. We identify an angle of the G2 background dual to the anomalous U(1)R current in field theory. This angle is not an isometry of the metric and we therefore develop a theory of “massive isometry” to describe fluctuations about such angles. Another example of a massive isometry occurs in the Atiyah-Hitchin metric. © 2004 The American Physical Society URL:
