Beam-helicity asymmetry arising from deeply virtual Compton scattering measured with kinematically complete event reconstruction
The HERMES Collaboration, A. Airapetian, N. Akopov +133
The beam-helicity asymmetry in exclusive electroproduction of real photons by the longitudinally polarized HERA positron beam scattering off an unpolarized hydrogen target is measu…
Leading-Order Determination of the Gluon Polarization from high- Hadron Electroproduction
The HERMES Collaboration, A. Airapetian
Longitudinal double-spin asymmetries of charged hadrons with high transverse momentum have been measured in electroproduction using the \hermes\ detector at \hera. Processes…
Spin Density Matrix Elements in Exclusive rho^0 Electroproduction on 1H and 2H Targets at 27.5 GeV Beam Energy
HERMES Collaboration, A. Airapetian
Spin Density Matrix Elements (SDMEs) describing the angular distribution of exclusive rho^0 electroproduction and decay are determined in the HERMES experiment with 27.6 GeV beam e…
Hadronization in semi-inclusive deep-inelastic scattering on nuclei
The HERMES Collaboration, A. Airapetian
A series of semi-inclusive deep-inelastic scattering measurements on deuterium, helium, neon, krypton, and xenon targets has been performed in order to study hadronization. The dat…
Beam-Spin Asymmetries in the Azimuthal Distribution of Pion Electroproduction
HERMES Collaboration, A. Airapetian
A measurement of the beam-spin asymmetry in the azimuthal distribution of pions produced in semi-inclusive deep-inelastic scattering off protons is presented. The measurement was p…
