Query: Introduction to statistical models and non-extensive statistics   Quark matter is being expected to be found in heavy ion collisions on the
basis of calculations in the framework of traditional, extensive
thermodynamics. Recently a non-extensive generalization of the thermodynamics
is emerging in the theoretical research. We review here some basic concepts in
statistics, kinetic theory and thermodynamics, in particular those encountered
in non-extensive thermodynamics. This offers an introduction into the
theoretical basis of considering non-extensive parton kinetics for describing
the hadronization of quark matter.
