Is the polarized light flavor sea-quark asymmetric?
Simple formulas on $Δ\bar d(x)-Δ\bar u(x)$ are proposed for extracting their values from polarized deep-inelastic semi-inclusive data. The present SMC and HERMES data suggest that $Δ\bar d(x)-Δ\bar u(x)$ is slightly negative, though the precision of the data is not enough for confirming it.
