Description

The production of identified hadrons in jets in e+e− scattering allows for detailed analyses of fragmentation functions in a clean environment. We present our novel calculation of next-to-next-to leading order (NNLO) corrections to hadron-in-jets observables for the e+e− → 2j and e+e− → 3j processes. In particular, we study the impact of the choice of different fragmentation scales in our predictions to the comparison with experimental data.
