“…As the heavy baryon formalism is valid only for the small pion mass, we restrict the data points at pion masses less than 500MeV. Then it turns out that the chiral log term gives a strong m π dependence for small m π region and the extrapolated value is eventually comparable with the latest experimental value of deep-inelastic scattering reported by HERMES [7]. With this extrapolation, we obtain the quark spin contribution in the nucleon asà right panel of Fig.2.…”

“…In practice, however, determining the first moment requires an extrapolation of the experimental data to small values of x, where uncertainties are less under control. There is some tension between the two most recent analyses from HERMES [6,7], which rely on different techniques; the former favors a negative value for ∆s while the latter finds a result consistent with zero, within somewhat larger uncertainties.…”

“…Initially it provided critical information on the relative distribution of momentum between valence and sea quarks and the gluons. As the experimental capabilities have grown so have our ambitions and over the past decade semi-inclusive deep-inelastic scattering (SIDIS) has helped (along with Drell-Yan) to expand our knowledge of quark flavor structure [2][3][4][5][6][7][8][9][10]. With several new experimental facilities with 100% duty factor under construction, SIDIS will become even more important.…”
