Abstract:
We study the large NN limit of a little string theory that reduces in the IR to U(N) N=1{\cal N} =1 supersymmetric Yang-Mills with Chern Simons coupling kk. Witten has shown that this field theory preserves supersymmetry if kN/2k\geq N/2 and he conjectured that it breaks supersymmetry if k<N/2k< N/2. We find a non-singular solution that describes the k=N/2k=N/2 case, which is confining. We argue that increasing kk corresponds to adding branes to this solution, in a way that preserves supersymmetry, while decreasing kk corresponds to adding anti-branes, and therefore breaking supersymmetry.
