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. © 2011 Elsevier B.V. All rights reserved.
