dc.description.abstract | The value of the nucleon's flavour-singlet axial-charge extracted from polarised deep inelastic scattering is sensitive to the value of the octet axial-charge gA(8) which is usually taken from an analysis of hyperon β-decays within the framework of SU(3) symmetry, namely 0.58 ± 0.03. Using the Cloudy Bag model we find that the value of gA(8) is reduced by as much as 20% below the usual phenomenological value. This increases the value of the flavour-singlet axial-charge (gA(0) |inv) derived from deep inelastic data and significantly reduces the difference between it and gA(8). © 2010 Elsevier B.V.
