Abstract
We present results for the one-particle spectra in the superconducting stat e of a Hubbard model with an additional attractive nonlocal pairing interac tion solved within a suitable extended dynamical mean-field theory. The cal culations show that the one-particle spectrum becomes gapless for a finite Coulomb parameter in accordance with tunnel spectra. (C) 1999 Elsevier Scie nce B.V. All rights reserved.
