The Beam--Charge Azimuthal Asymmetry and Deeply Virtual Compton Scattering
The HERMES Collaboration, A. Airapetian
The first observation of an azimuthal cross--section asymmetry with respect to the charge of the incoming lepton beam is reported from a study of hard exclusive electroproduction o…

Subleading-twist effects in single-spin asymmetries in semi-inclusive deep-inelastic scattering on a longitudinally polarized hydrogen target
The HERMES Collaboration, A. Airapetian, :
Single-spin asymmetries in the semi-inclusive production of charged pions in deep-inelastic scattering from transversely and longitudinally polarized proton targets are combined to…

First Measurement of the Tensor Structure Function of the Deuteron
The HERMES Collaboration, A. Airapetian
The \Hermes experiment has investigated the tensor spin structure of the deuteron using the 27.6 GeV/c positron beam of \Hera. The use of a tensor polarized deuteron gas target wit…
