Abstract
We perform a combined next to leading order analysis of both inclusive and semi-inclusive polarized deep inelastic scattering data, assessing the impa ct of new data on the extraction of the sea quark and gluon spin dependent densities. In particular, we find that semi-inclusive data show a clear pre ference for a positive Delta(u) over bar distribution, although are almost insensitive to different alternatives to Delta(d) over bar.
