Abstract
The mean-field theory of the two-particle resonance model of high-Tc superconductivity is reexamined and solved exactly. The dependence of Tc on (m*m) is dramatic Tc→0 at (m*m)=1, and (m*m)→∞ the heavy-fermion limit peaking at (m*m)≅5. The gap-to-Tc ratio, Hc(0), and specific-heat jump at Tc, ΔCv, have BCS values for all m*m. Tc is a linear function of hole concentration.
