Title: Role of vector mesons in high-[ital Q][sup 2] lepton-nucleon scattering

Abstract

The possible role played by vector mesons in inclusive deep-inelastic lepton-nucleon scattering is investigated. In the context of the convolution model, we calculate self-consistently the scaling contribution to the nucleon structure function using the formalism of time-ordered perturbation theory in the infinite momentum frame. Our results indicate potentially significant effects only when the vector-meson--nucleon form factor is very hard. Agreement with the experimental antiquark distributions, however, requires relatively soft form factors for the [pi][ital N], [rho][ital N], and [omega][ital N] vertices.
