Consistent Treatment of Relativistic Effects in Electrodisintegration of the Deuteron

Abstract

The influence of relativistic contributions to deuteron electrodisintegration is systematically studied in various kinematic regions of energy and momentum transfer. As theoretical framework the equation-of-motion and the unitarily equivalent S-matrix approaches are used. In a (p/M)-expansion, all leading order relativistic $π$-exchange contributions consistent with the Bonn OBEPQ model are included. In addition, static heavy meson exchange currents including boost terms, $γπρ/ω$-currents, and $Δ$-isobar contributions are considered. Sizeable effects from the various relativistic two-body contributions, mainly from $π$-exchange, have been found in inclusive form factors and exclusive structure functions for a variety of kinematic regions.
