Abstract:
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.
