Open AccessExclusive leptoproduction of real photons on a longitudinally polarised hydrogen target
Polarisation asymmetries are measured for the hard exclusive leptoproduction of real photons from a longitudinally polarised hydrogen target. These asymmetries arise from the deeply virtual Compton scattering ...
