Global analysis of helicity PDFs: past - present - future
D. de FlorianR. SassotM. StratmannW. Vogelsang
文献摘要
We discuss the current status of the DSSV global analysis of helicity-dependent parton densities. A comparison with recent semi-inclusive DIS data from COMPASS is presented, and constraints on the polarized strangeness density are examined in some detail.
