Abstract
The strongly correlated two-dimensional CuO2 layer is studied to identify the mechanism of possible pairing superconductivity. The correlative motions of O and Cu holes are treated by a reasonable mean-field theory, and we find that holes on oxygen sites couple strongly to Cu holes to form Cu-O spin singlet pairs, which in turn interact strongly with the Cu resonating-valence-bond state and lead to an effective attraction between O holes, which is responsible for superconductivity.
