An Alternative Approach to Semi-inclusive DIS and A Model Independent Determination of D_u^{\pi^+}, D_d^{\pi^+} and D_s^{\pi^+}

Abstract

We discuss how to extract the polarized parton densities and fragmentation functions in a model independent way from SIDIS, and present results for D_{u,d,s}^{\pi^+}.
