    "abstract": "In the theory of deep inelastic scattering (DIS) the final state interaction\n(FSI) between the struck quark and the remnants of the target is usually\nassumed to be negligible in the Bjorken limit. This assumption, still awaiting\na full validation within nonperturbative QCD, is investigated in a model\ncomposed by two relativistic particles, interacting via a relativistic harmonic\noscillator potential, within light-cone hamiltonian dynamics. An\nelectromagnetic current operator whose matrix elements behave properly under\nPoincar\\\u0027e transformations is adopted. It is shown that: i) the parton model is\nrecovered, once the standard parton model assumptions are adopted; and ii) when\nrelativistic, interacting eigenfunctions are exactly taken into account for\nboth the initial and final states, the values of the structure functions,\naveraged over small, but finite intervals of the Bjorken variable $x$, coincide\nwith the results of the parton model in the Bjorken limit.",
