We present an overview of information theory approach (both in its extensive and nonextensive versions) applied to high-energy multiparticle production processes. It will be illustrated by analysis of single-particle distributions measured in proton–proton, proton–antiproton and nuclear...

The application of information theory approach (both in its extensive and nonextensive versions) to high-energy multiparticle production processes is discussed and confronted with experimental data on e+e− annihilation processes, pp and p̄p scatterings and heavy ion collisions.
