Flavour Separation of Helicity Distributions from Deep Inelastic Muon-Deuteron Scattering

COMPASS Collaboration, M. Alekseev

We present a LO evaluation of helicity densities of valence, Δu_v+Δd_v, non-strange sea, Δ\bar{u}+Δ\bar{d}, and strange quarks, Δs (assumed to be equal to Δ\bar{s}). They have been…
