Por Carlota Andrés (LIP).
Traditionally parton distribution functions (PDFs) and fragmentation functions (FFs) have been independently obtained from multiple high-energy scattering experiments by means of a technique known as global analysis. In this talk, I will show the first simultaneous Monte Carlo global analysis of both PDFs and FFs, which includes data on inclusive and semiinclusive deep-inelastic scattering, Drell-Yan lepton-pair production, and single-inclusive e+ e- annihilation. Our study reveals significant correlations between the strange quark PDF and the strange-to-kaon fragmentation function needed to simultaneously describe semiinclusive K production data and inclusive K spectra in e+ e- annihilation, and suggests a suppression of the strange quark distribution at intermediate x values.
