Deep-inelastic scattering in a modified bag model

Abstract

Deep-inelastic scattering structure functions are calculated in a cloudy bag model with surface dynamics. The model is solved in the adiabatic approximation, the resultant wave functions are projected onto states of zero momentum, and valence-quark distributions are calculated. These distributions are evolved to $Q^2$=15 ${\mathrm{GeV}}^2$ using QCD perturbation theory, where they are compared with experiment. Qualitative agreement is achieved.
