Pion cloud of the nucleon and its effect on deep-inelastic structure

Abstract

In this paper we present the calculation of deep-inelastic scattering structure functions of nucleons dressed by pions. The calculation is performed within the convolution model. We present analytic results for quark and antiquark distributions of a given flavor and spin and numerical results of those structure functions that are likely to be most affected by the dressing of the nucleon. We allow for the probe scattering off both nucleons and Δ’s. Diagrams where it scatters off the pions themselves are not taken into account. For the numerical results we look only at combinations of structure functions where these do not contribute.
