Although the effective interaction $U_\\text{eff}=U-J$ is predominantly repulsive, an attractive component arising from the Hund's coupling parameter $J$ is sufficient to bind fractional charges. Evaluating this binding energy within a single-band Hubbard model yields a superconducting pairing gap $\\Delta_0$ and estimates the transition temperature $T_c$.
