Quark Helicity Distributions from Longitudinal Spin Asymmetries in Muon-Proton and Muon-Deuteron Scattering
We present a leading order evaluation of the helicity distributions for the three lightest quarks and anti-quarks flavours, derived from the double-spin asymmetries measured by the COMPASS collaboration. The data, obtained by scattering a 160 GeV muon beam off longitudinally polarised NH$_{3}$ and...
