We have measured the moment Asin ϕ LU corresponding to the polarized electron beam-spin asymmetry in semi-inclusive deep inelastic scattering. Asin ϕ LU is a twist-3 quantity providing information about quarkgluon correlations. Data were taken with the CLAS Spectrometer at Jefferson Lab using a 5.498 GeV longitudinally polarized electron beam and an unpolarized liquid hydrogen target. All three pion channels (πþ, π0 and π−) were measured simultaneously over a large range of kinematics within the virtuality range Q2 ≈ 1.0–4.5 GeV2. The observable was measured with better than 1% statistical precision over a large range of z, PT, xB, and Q2, which permits comparison with several reaction models. The discussed measurements provide an upgrade i...
