A long-standing unsolved problem is how a microscopic theory of superconductivity in cuprate superconductors based on the charge-spin separation can produce a large electron Fermi surface (EFS). Within the framework of the kinetic-energy driven superconducting mechanism, a full charge-spin recombination scheme is developed to fully recombine a charge carrier and a localized spin into an electron, and then is employed to study the electron-momentum distribution in cuprate superconductors. In particular, the theory shows that the underlying EFS fulfills Luttinger’s theorem, and the sum rule for the constrained electron is obeyed.
