Abstract
We have investigated whether electron-hole composite quasiparticles in ${\mathrm{CuO}}_{2}$ planes can drive the hole-doped high-${T}_{c}$ superconductivity. Using this quasiparticle concept, we derive a Kondo-type interaction mediated by the effective Gell-Mann and Breuckner-type phonon. It is shown that this interaction opens a superconducting gap near the Fermi level. We explain the resistivities in the a-b plane and also along the c axis using the same concept of superexchange interactions. We have also found that the measured magnetic susceptibility and nuclear-spin relaxation rates can be explained using the present theoretical scheme in a consistent way.
