Abstract

In this Letter, we show that the distribution of the longitudinal momentum fraction of charged hadrons dN/dz inside jets stemming from proton-proton collisions at s=7TeV center of mass energy can be described by a statistical jet-fragmentation model. This model combines microcanonical statistics and super-statistics induced by multiplicity fluctuations. The resulting scale dependence of the parameters of the model turns out to be similar to what was observed in electron-positron annihilations in Urmossy et al. (2011) [7].
