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.
