Spherical deconstruction

We present evidence that N=1∗ SUSY Yang-Mills provides a deconstruction of a six-dimensional gauge theory compactified on a two-sphere. The six-dimensional theory is a twisted compactification of N=(1,1) SUSY Yang-Mills theory of the type considered by [J. Maldacena, C. Nuñez, Towards the large N limit of pure N=1 super-Yang-Mills, Phys. Rev. Lett. 86 (2001) 588, hep-th/0008001]. In particular, we calculate the full classical spectrum of the N=1∗ theory with gauge group U(N) in its Higgs vacuum. In the limit N→∞, we find an exact agreement with the Kaluza-Klein spectrum of the MN compactification.
