Query: Perturbative renormalization of lattice N=4 super Yang-Mills theory   We consider N=4 super Yang-Mills theory on a four-dimensional lattice. The
lattice formulation under consideration retains one exact supersymmetry at
non-zero lattice spacing. We show that this feature combined with gauge
invariance and the large point group symmetry of the lattice theory ensures
that the only counterterms that appear at any order in perturbation theory
correspond to renormalizations of existing terms in the bare lattice action. In
particular we find that no mass terms are generated at any finite order of
perturbation theory. We calculate these renormalizations by examining the
fermion and auxiliary boson self energies at one loop and find that they all
exhibit a common logarithmic divergence which can be absorbed by a single
wavefunction renormalization. This finding implies that at one loop only a fine
tuning of the finite parts is required to regain full supersymmetry in the
continuum limit.
