We use an exact {ital holon} and {ital spinon} Landau-liquid functional, which describes the holon-spinon interactions at all scattering orders, to study correlation functions of integrable multicomponent many-particle problems showing both linear and nonlinear energy bands. Motivated by recent photoemission experiments, we consider specific cases when the dominant nonlinear band terms are quadratic and apply our results to the evaluation of the half-filling 1D Hubbard model one-particle spectral functions beyond conformal field theory. {copyright} {ital 1999} {ital The American Physical Society }
