Abstract

The beam-helicity asymmetry in associated electroproduction of real photons, ep → eγπN, in the Δ(1232)-resonance region is measured using the longitudinally polarized Hera positron beam and an unpolarized hydrogen target. Azimuthal Fourier amplitudes of this asymmetry are extracted separately for two channels, ep → eγπ
