Alekseev MG, Alexakhin VY, Alexandrov Y, et al. Quark helicity distributions from longitudinal spin asymmetries in muon-proton and muon-deuteron scattering. Phys.Lett. B. 2010;693(3):227-235.Double-spin asymmetries for production of charged pions and kaons in semi-inclusive deep-inelastic muon scattering have been measured by the COMPASS experiment at CERN. The data, obtained by scattering a 160 GeV muon beam off a longitudinally polarised NH_3 target, cover a range of the Bjorken variable x between 0.004 and 0.7. A leading order evaluation of the helicity distributions for the three lightest quarks and antiquark flavours derived from these asymmetries and from our previous deuteron data is presented. The resulting values of the sea quark d...
