Hadronization corrections to helicity components of the fragmentation function

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.
