Title: N=4 super Yang-Mills on the Lattice

Abstract: 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.
