Phenomenological Analysis of Data on Inclusive and Semi-inclusive Spin Asymmetries

Abstract

We present a phenomenological analysis of data on both inclusive and semi-inclusive spin asymmetries. We examine the impact of the semi-inclusive results presented by SMC on the determination of polarized parton distributions performing global fits with different sets of observables. We discuss the flavour dependence of the polarized sea inside a nucleon.
