Nonextensive Statistics and Multiplicity
Distribution in Hadronic Collisions C.E. Aguiar
and T. Kodama Instituto de Física Universidade
Federal do Rio de Janeiro Abstract The
multiplicity distribution of particles in
relativistic gases is studied in terms of
Tsallis' nonextensive statistics. For an
entropic index q gt 1 the multiplicity
distribution is wider than the Poisson
distribution with the same average number of
particles, being similar to the negative binomial
distribution commonly used in phenomenological
analyses of hadron production in high-energy
collisions.
