The universal theory for the high-energy spectral properties of a wide class of one-dimensional correlated systems based on the mobile-quantum-impurity model has not been extended to finite-range interactions. Here that problem is addressed by adding to the Hubbard model screened-Coulomb potentials of general form. A representation in terms of neutral fractionalized particles whose scattering corresponds to the unitary limit as that in shells of neutron stars reveals unexpected universality. It concerns the independence from the short-distance part of the potentialsof the high-energy one-electron spectral functions near and at the (k,omega)-plane singular features where most of the weight is located. Such systems are found to share universal properties with three-dimensional atomic scattering problems for which the potential at small distances can be replaced by a universal energy-independent boundary condition. The universal theory is successfully applied to the angle-resolved-photoemission spectroscopy in one-dimensional states on a InSb(001) surface covered with Bi.
