title = "Spin dependent fragmentation functions analysis at Belle",
abstract = "The chiral-odd fragmentation functions (FF) play an important role in the understanding of the transverse structure of the nucleon. Additionally the so-called Collins FF seems to be closely connected to the QCD vacuum itself. HERMES has given a first hint that this FF is nonzero, however in order to measure the quark transversity one needs these FFs to be precisely known. We have updated the previous analysis from 29.0 fb-1 to 547 fb -1 of data collected by the Belle experiment at the KEKB e +e- collider to measure azimuthal asymmetries for different charge combinations of pion pairs and thus access the Collins FF.",
