Description

Simple formulas on Δd-bar(x)-Δu-bar(x) are proposed for extracting their values from polarized deep-inelastic semi-inclusive data. The present SMC and HERMES data suggest that Δd-bar(x)-Δu-bar(x) is slightly negative, though the precision of the data is not enough for confirming it. (author)
