N=4 super Yang-Mills on the Lattice
I will describe a new lattice formulation of N=4 SYM which has the merit of preserving one exact supersymmetry for non-zero lattice spacing. This exact supersymmetry ensures that the only counterterms needed in the lattice theory correspond to renormalizations of existing terms in the bare lattice action. A one loop calculation reveals that the lattice theory requires no fine tuning to target the continuum N=4 theory as the lattice spacing is reduced to zero. The strong coupling regime can be probed using the same Monte Carlo techniques used in lattice QCD.
