Hadronization corrections to helicity components of the fragmentation function

Abstract. In the hadronic decays of $Z^0$, gluon emission leads to the appearance of the longitudinal component of the fragmentation function, $F_{\mathrm{L}}$. Measurement of $F_{\mathrm{L}}$ and the transverse component, $F_{\mathrm{T}}$, could thus provide insight into the gluon fragmentation function. However, hadronization corrections at low x can be significant. Here we present a method of accounting for such corrections, using the Jetset event generator as illustration.
