Abstract
The effect of Coulomb correlations on the electronic structure of Cu-oxide superconductors are determined with the many-body corrections to the known band structure made by calculating perturbatively the self-energy due to the on-site Coulomb interaction at the Cu sites. The effective mass enhancement at EF, renormalized band dispersions, and the energy dependence of the band state broadening for Nd2-xCexCuO4 are predicted and found to be in agreement with observations in other Cu-oxide superconductors with a choice of the effective Coulomb interaction parameter U=3 eV.
