Description

The scaling of charged hadron fragmentation functions to the Tsallis distribution for the momentum fraction 0.01≤x≤0.2 is presented for various e+e- collision energies. A possible microcanonical generalisation of the Tsallis distribution is proposed, which gives good agreement with measured data up to x∼1. The proposal is based on superstatistics and a Koba-Nielsen-Olesen (KNO) like scaling of multiplicity distributions in e+e- experiments.
