Calculations of Higher Twist Distribution Functions in the MIT Bag Model

Abstract

We calculate all twist-two, three and four parton distribution functions involving two quark correlations using the wavefunction of the MIT bag model. The distributions are evolved up to experimental scales and combined to give the various nucleon structure functions. Comparisons with recent experimental data on higher twist structure functions at moderate values of $Q^2$ give good agreement with the calculated structure functions.
