Abstract

We show that non-singlets in semi-inclusive DIS with pi^± determine without assumptions Delta u_V, Delta d_V and D_u^{π+ - 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 D_d^{K+ - K-}=0. Measurements with charged K^± and neutral K0+bar K0 in semi-inclusive DIS and e+e--annihilation determine D_u,d,s^{K+ + K-} without any assumptions and allow tests of LO approximation in QCD.
