Abstract

We study the annihilation channel in antiproton-nucleon collisions with production of a single charged or neutral pion and a lepton-antilepton pair. These processes offer a unique possibility to study the nucleon electromagnetic form factors in the unphysical region. The differential cross section in an experimental set-up, where the pion is fully detected, is given with explicit dependence on the relevant nucleon form factors.

Keywords

antiproton-nucleon collision; nucleon electromagnetic form factors; unphysical region
