The Bethe-Heitler Process in Polarized Photon-Nucleon Interactions
T.Gehrmann (DESY)🇩🇪 · M.Stratmann (Univ. Dortmund)🇩🇪
Abstract
We calculate the Bethe-Heitler cross section for the production of lepton pairs in the field of a longitudinally polarized nucleon, taking into account the lepton masses and the target mass. This process is a dominant background to the detection of open charm from semi-leptonic decay modes, which is a potential probe of the polarized gluon distribution in the nucleon.
