Semi-inclusive hadron-production processes are becoming important in high-energy hadron reactions. They are used for investigating properties of quark-hadron matters in heavy-ion collisions, for findi...

The Nambu{Jona-Lasinio (NJL) - Jet model provides a sound framework for calculating the frag-
mentation functions in an e ective chiral quark theory, where the momentum and isospin sum rules are sati...
Momentum sum rules for fragmentation functions are considered. In particular, we give a general proof of the Sch\"afer-Teryaev sum rule for the transverse momentum dependent Collins function. We also ...
