Abstract

We propose new formulas for extracting a difference of the polarized light sea-quark density, Δ d(x)-Δ u(x), from polarized deep-inelastic semi-inclusive data. We have estimated the value of it from the present experimental data measured by SMC and HERMES groups. Although the data might suggest a violation of polarized light flavor sea-quark symmetry, the precision of the present data is not enough for confirming it.
