M5 branes on ℝ1,1 ×Taub-NUT

Andreas Gustavsson (Physics Department, University of Seoul, Seoul, 02504, Korea)

We study M5 branes on ℝ1,1 ×Taub-NUT that we view as a singular fibration. Reducing the M5 branes along the fiber gives 5d SYM. Due to the singularity, this 5d theory has a gauge anomaly and it is not supersymmetric. To cure these problems we add a supersymmetric gauged chiral WZW theory on the 2d submanifold where the circle fiber vanishes. In addition we add a mass term for the five scalar fields located on this submanifold. With all this, we obtain a fully supersymmetric and gauge invariant theory.
