The Relationship

In the framework of the recombination model we determine the shower parton distributions (SPDs) with the fragmentation functions (FFs) for mesons and then predict the fragmentation functions for baryons. We get the fragmentation functions of gluon splitting into charmed hadrons. We show the relationship of fragmentation functions for mesons and baryons and find that they are not independent if the hadronization of the shower partons is taken into account.

Qcd Analysis

An extraction of the parton distributions of the proton by a next-to-leading order QCD fit in the framework of the Standard Model is presented. The fit implements a novel decomposition of the quark species into up- and down-type quark distributions, which is the key to enable a determination of flavor separated parton distributions from a single experiment. The fit is performed on the inclusive unpolarized neutral and charged current cross-section measurements by the H1 collaboration at HERA. The discussion of uncertainties of parton distribution functions is based upon but extends the QCD analysis published together with the H1 data.

Fragmentation Functions

Unpolarised semi-inclusive deep inelastic scattering is receiving a growing interest as a powerful tool to access poorly known transverse momentum dependent parton distributions and fragmentation functions that play a key role in many processes, in particular in the study of the spin structure of the nucleon. These functions can be investigated through experimental observables. New results on these observables by the COMPASS experiment at CERN will be shown and discussed.
