Description
In order to obtain precise information on helicity and transversity
distributions from semi-inclusive measurements in DIS and proton-proton
collisions a good knowledge of fragmentation functions is necessary.
The Belle experiment at the asymmetric e+e- collider KEKB can provide precise
spin averaged and spin dependent fragmentation functions such as the Collins
function and the interference fragmentation function.
Recent results will be shown.
