Fragmentation functions and their role in determining the polarized parton densities

S. Kretzer, E. Leader, E. Christova

We extract the pion fragmentation functions and their uncertainties from a judicious choice of e+e- and semi-inclusive DIS data. These are used to study the error propagation in th…

Fragmentation functions from semi-inclusive DIS pion production and implications for the polarized parton densities

E. Christova, S. Kretzer, E. Leader

By combining recent HERMES data on semi-inclusive DIS $π^{\pm}$ -production with the singlet fragmentation function $D_{Σ}^{π^{+}}$ , which is well determined from $e^{+} e^{-}$ data, we are ab…
