- Description
- A quark-diquark picture of the nucleon, previously introduced in the description of several exclusive and inclusive processes at intermediate <math>Q^2\,\!</math> values, is found to accurately model the higher-twist data on the unpolarized proton structure function <math>F^p_2(x,Q^2)\,\!</math> . 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.
