Description

It has been shown that power-law hadron spectra observed in jets stemming from high-energy ee and pp collisions can be described by a statistical hadronisation model based on microcanonical statistics and superimposed Negative-Binomial (NBD) multiplicity fluctuations [1,2,3]. In this talk, applications of this model to ep DIS are discussed: fits to fragmentation functions and multiplicity distributions are presented. Besides, applications of such fragmentation model to heavy-ion collisions are also discussed based on [4,5]. Refs.: [1] Phys. Lett. B, 718 (2012) 125-129, arXiv:1204.1508 [2] Phys. Lett.
