The nuclear collisions at relativistic energy offer the right kind of environment to explore a variety of phases transitions related to hot and dense nuclear matter to enhance our existing knowledge about the formation and decay of highly exited nuclear matter. The compression of nuclear matter and its subsequent expansion results in production of particles along with the disassembly of the expanded nuclear system into multiparticle production.

Multiparticle production is the“first-day” research topic in the collisions and is related to the state of deconfined quarks and gluons (quark gluon plasma (QGP)) which is predicted by the quantum chromodynamics (QCD). Multiparticle production is especially related to the statistical properties of global observables, dynamical evolution of interacting system, various distributions and correlations, and so on.

From fixed target experiments to collider experiments, multiparticle production research covers various collisions over an energy range from GeV to TeV. Previously, a few accelerators provided hadron and heavy ion beams for the studies of multiparticle production. Presently, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) and the Large Hadron Collider (LHC) at European Laboratory for Particle Physics (CERN) provide proton and heavy ion beams for our studies. This is an important issue for cosmic ray physics also because more particles are produced in cosmic ray-induced nuclear collisions at higher energy.

We intend to publish a special issue on multiparticle production in high energy collisions. The editors would welcome original research articles as well as review articles from both the theorists and experimentalists. Potential topics include, but are not limited to:

• Multiplicity distributions and correlations
• Rapidity or pseudorapidity distributions and correlations
• Transverse momentum distributions and correlations
• Anisotropic flow effects and correlations
• Statistical and dynamical fluctuations
• Final-state distributions and dynamical evolution
• Final-state distributions and statistical behaviors
