摘 要：We demonstrate that a dsuperconducting pairing is naturally associated with the screened Coulomb interaction V(q,ω)within the CuO plane of high T *** pairing instability arises(via the dielectric constant)from wave-vector structure in V(q,ω)at q=(π,π),which is associtated with 2D Van Hove and local field *** results,which are independent of the handstructure,suggest that direct Coulomb interactions are significant(when compared to the spin channel) and will,at the least,enhance any other underlying mechanism for d wave pairing.
