Abstract
Within the spin-fermion model for cuprate superconductors, the influence of the intersite Coulomb interactions V2 and V′2 between holes located at the next-nearest-neighbor oxygen ions of CuO2 plane on the implementation of the dx2−y2-wave pairing is studied. It is shown that d-wave pairing can be suppressed only for unphysically large values of V2 and V′2.
