Descripción
Fragmentation functions (FFs) describe the formation of final state particles from a partonic initial state and are directly related to the QCD phenomenon of confinement. Precise knowledge of these functions is a key ingredient in accessing quantities such as the nucleon spin structure in semi-inclusive deep inelastic scattering (SIDIS) and proton-proton collisions. Using Belle data, we study the Collins fragmentation mechanism in kaon production. Such mechanism entails a correlation between the transverse polarization of the fragmenting quark and the outgoing direction of the produced hadron. Knowledge of the Collins FF is a necessary input in the study and extraction of the transversity distribution function from SIDIS and $pp$ reaction.
