Towards a universal law of particle production in heavy-ion collisions.

In this paper we study the charged particle and transverse energy production mechanism from AGS to LHC energies in the framework of nucleon and quark participants as well. A universal function which is a combination of logarithmic and power-law, describes the charged particle and transverse energy production both at nucleon and quark participant level quite well for the whole range of collision energies. We give the predictions for dNch/dη, dET/dη and the barometric observable, ET/Nch for Pb+Pb collisions at [formula]. [ABSTRACT FROM AUTHOR]
