Abstract

In order to measure the quark transverse spin distribution of the nucleon one has to combine it with another chiral-odd object. This can for example be the Collins fragmentation function or the Interference fragmentation function. At the KEKB e+e-collider the Belle experiment has published the first measurement of the Collins fragmentation function with a data sample of 29 fb-1. In an updated analysis a data sample of 547 fb-1 has been analyzed reducing the statistical errors significantly.
