Description
By exploiting crossing symmetry, a unified treatment of the pion, kaon, proton distribution functions (DFs) and fragmentation functions (FFs) was accomplished. It gives insights into the link between two important phenomena in QCD: EHM and confinement. After evolving to higher scale, it provides coherent picture of fragmentation across all parton types. The obtained FFs conform with the physical expectations for FF behaviour on the endpoint domains.
