摘要:In the two papers published recently, (1, 2) we apply collinear expansion to both inclusive (e(+)e(-) -> h + X) and semi-inclusive (e(+)e(-) -> h + (q) over bar + X) hadron production in e(+)e(-) annihilation to derive a formalism suitable for a systematic study of leading as well as higher twist contributions to fragmentation functions at the tree level. We carry out the calculations for hadrons with spin-0, spin-1/2 as well as spin-1. This proceeding is mainly a summary of these two papers.
