    • We have done a (Formula presented), order (Formula presented) calculation of the imaginary part of the self-energy (Formula presented) to check explicitly our large d results. To avoid complications from nesting or Van Hove singularities, we used a circular Fermi surface. We find to leading order in (Formula presented) and in (Formula presented) that at (Formula presented), (Formula presented) which is indeed the (Formula presented) Fermi-liquid result. The calculation proceeds in the same way as in the weak-coupling Hubbard model, see, e.g., C. Hodges, H. Smith, and J. W. Wilkins, Phys. Rev. B 4, 302 (1971).
