Abstract
We demonstrate the existence of a simple physical picture of superconductivity for extremely over-doped CuO2 planes. It has all the characteristic features of HTS, such as a high superconducting transition temperature, the \(d_{x^2 - y^2 } \) symmetry of the order parameter, and the coexistence of a single-electron Fermi surface and a pseudogap in the normal state. The values of the pseudogap are calculated for different doping levels. Orbital paramagnetism of preformed pairs is predicted.
