Statistical hadronization and multi particle production in high energy interactions

Abstract

The particle collisions at very high centre of mass energies are the finest tools to understand underlying dynamics of multiparticle production in such collisions. Various high energy accelerators have been built to collide particles such as hadrons, leptons and heavy ions to study the fundamental physics and the newlineparticles produced in these collisions are recorded in the particle detectors to extract the information about their charges, momenta and energies. The number of particles produced in the final state after the interaction is termed as particle multiplicity and the distribution of these final states particles produced is known as multiplicity distribution (MD). Study of charged particle multiplicity distributions provides an understanding of the particle production mechanism, as the particles produced in these interactions follow certain production rules and conservation laws. Various theoretical and phenomenological models based on hydrodynamics, thermodynamics and statistics have been successfully used in describing the distributions of these final state particles. newline
