Description
We introduce a novel fragmentation function parametrization
based on the non-extensive statistical phenomena. Parametrization of
the leading order fragmentation functions is made for the
hadronization of partons to charged pions, kaons, and protons. The
obtained parameters are result of fit to data from electron-positron
annihilation, however contains information on the statistical
properties of the collisional system. Results were compared to other,
widely-used fragmentation function parametrization. We also tested by calculating identified high pT hadron production in proton-proton collision, which is also compared to measured data.
