    "abstract": "We calculate order $\\alpha_s$ color magnetic corrections to the valence quark\ndistributions of the proton using the Los Alamos Model Potential wavefunctions.\nThe spin-spin interaction breaks the model SU(4) symmetry, providing a natural\nmechanism for the difference between the up and down distributions. For a value\nof $\\alpha_s$ sufficient to produce the $N-\\Delta$ mass splitting, we find up\nand down quark distributions in reasonable agreement with experiment.",
