Query: A chiral theory of strange sea distributions in the nucleon   Theoretical predictions are given for the strange sea distributions in the
nucleon based on 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 the
longitudinally polarized distribution functions than for the 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.
