<dt>Description</dt>
<dd>A quark-diquark picture of the nucleon, previously introduced in the description of several exclusive and inclusive processes at intermediate &lt;math&gt;Q^2\,\!&lt;/math&gt; values, is found to accurately model the higher-twist data on the unpolarized proton structure function &lt;math&gt;F^p_2(x,Q^2)\,\!&lt;/math&gt; . The main results of the model are summarized. The emerging set of parameters is consistent with the diquark properties suggested by other experimental and theoretical analyses. Higher-twist corrections to the Bjorken and Gottfried sum rule are also estimated in the framework of the same quark-diquark model. The resulting corrections to both sum rules turn out to be negligible.</dd>
