2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/226956We present an overview of possible imprints of non-extensitivity in particle and nucler physics. Special emphasis is put on the intrinsic fluctuations present in the system under consideration as the possible source of nonextensivity. The possible connection of nonextensivity and the self organized criticality apparently being observed in some cosmic rays and hadronic experiments will also be discussed.Contribution to International School and Conference on "Non Extensive Thermodynamics and physical applications", Villasimius-Capo Boi (Cagliari), Italy, 23-30 March 2001High Energy Physics - PhenomenologyCondensed MatterNuclear Theorytext
