Fragmentation function measurements at Belle

Conference Paper

The precision measurement of fragmentation functions is an important requirement to study the spin structure of the nucleon. Unpolarized fragmentation functions at reasonably low scale and high fractional energy are necessary to complement the measurements mostly performed at LEP in order to obtain high enough precision for measurements at semi-inclusive DIS experiments and at RHIC. Those can be obtained from the abundant data collected with the Belle detector at the e +e - collider KEKB. In addition one can cleanly measure the transversely polarized fragmentation functions such as the Collins fragmentation function and the interference fragmentation functions. Both have been obtained with great precision at Belle. © 2011 American Institute of Physics.
