    "abstract": "Using a quark model, we study the effect of charge symmetry breaking on the\nvalence quark distributions of the nucleon. The effect due to quark mass\ndifferences and the Coulomb interaction of the electrically charged quarks is\ncalculated and, in contrast to recent claims, found to be small. In addition,\nwe investigate the effect of charge symmetry breaking in the confining\ninteraction, and in the perturbative evolution equations used to relate the\nquark model distributions to experiment. We find that both these effects are\nsmall, and that the strong charge symmetry breaking effect included in the\nscalar confining interactions may be distinguishable from that generated by\nquark mass differences.",
