The Bethe-Heitler Process in Polarized Photon-Nucleon Interactions
arXiv:hep-ph/9706414 · doi:10.1103/PhysRevD.56.5839
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.
