On the Sensitivity of the Polarized Parton Densities to Flavour SU(3) Symmetry Breaking
Abstract
Motivated by the possibility that it may be misleading to assume SU(3) symmetry in the analysis of hyperon β-decays, we study the sensitivity of the polarized parton densities, derived from the world data on inclusive polarized deep inelastic lepton-nucleon scattering, to variation of the value of the nonsinglet axial charge a8 from its SU(3) value of 3F-D.
