Stability of the d-wave pairing with respect to the intersite Coulomb repulsion in cuprate superconductors

Within the spin-fermion model for cuprate superconductors, the influence of the intersite Coulomb interactions V₂ and ${V\prime }_2$ between holes located at the next-nearest-neighbor oxygen ions of CuO₂ plane on the implementation of the $d_{x^2-y^2}$-wave pairing is studied. It is shown that d-wave pairing can be suppressed only for unphysically large values of V₂ and ${V\prime }_2$.
