Global Analysis of Fragmentation Functions for Protons and Charged Hadrons
read the original abstract
We present new sets of fragmentation functions for protons and inclusive charged hadrons obtained in combined NLO QCD analyses of single-inclusive hadron production in electron-positron annihilation, proton-proton collisions, and deep-inelastic lepton-proton scattering. These analyses complement previous results for pion and kaon fragmentation functions with charge and flavor discrimination. The Lagrange multiplier technique is used to assess the uncertainties in the extraction of the new sets of fragmentation functions.

Determination of Fragmentation Functions from Charge Asymmetries in Hadron Production
Non-singlet fragmentation functions of pions and kaons are determined at NNLO QCD from charge asymmetry measurements in e+e- annihilation and SIDIS, yielding a scaling index of 0.7 and strangeness suppression of 0.5.

Proton-Proton to Antinucleon Cross Sections for Cosmic Ray Applications
NLO perturbative QCD calculations predict only a mild few-percent excess of antineutrons over antiprotons in pp collisions, not supporting the ~30% excess reported by NA49.
