The Structure of the Pion and Nucleon, and Leading Neutron Production at HERA

Abstract

Attention is paid to recent results from the ZEUS Collaboration on the photo- and electro- production of leading neutrons in e^+ p collisions at HERA. Some implications for the structure of the pion and the nucleon are discussed.Comment: 10 pages with no figures, Latex, to be published in Nucl. Phys.
