概要

• 論文の詳細を見る

• Theoretical predictions are given for the strange sea distributions in the nucleon on the basis of the flavor SU(3) chiral quark. soliton model, with emphasis upon the asymmetry of quark and antiquark distributions. We find that the quark-antiquark asymmetry of the strange sea is much larger for longitudinally polarized distribution functions than for unpolarized ones. A preliminary comparison with the CCFR data for the unpolarized s-quark distribution and with the LSS fits of the longitudinally polarized distribution functions is encouraging.
