Abstract

Polarized vector-meson production in semi-inclusive electron-nucleon scattering with longitudinally polarized electron beam has been investigated. A Drell-Yan-like representation for the spin-density matrix elements of a vector meson that takes into account the leading radiative corrections is derived. The calculations have been performed for two widely used reference systems, the Gottfried-Jackson and the helicity systems.
