Abstract

We show that non-singlets in semi-inclusive DIS with pi determine without assumptions Delta uV, Delta dV and Duπ+ - pi-. Non-singlets in SIDIS and inclusive e+e- -annihilation with K determine (s-bar s) and (Delta s-Delta bar s), but an assumption is necessary -- we choose as most natural DdK+ - K-=0. Measurements with charged K and neutral K0+bar K0 in semi-inclusive DIS and e+e--annihilation determine Du,d,sK+ + K- without any assumptions and allow tests of LO approximation in QCD.
