Soft Physics, Centrality and Multiplicity at RHIC
摘要
The inclusive spectra so far accumulated at the Relativistic Heavy Ion Collider (RHIC) at energies of and 200 GeV are examined within the hadronic simulation LUCIFER. What emerges at this juncture is a comprehensive and clear picture of soft physics which apparently dominates the intermediate and later stages of the ion collisions. The focus is on energy and centrality dependence of the mid-rapidity charged spectra, using an analysis based for the most part on production and rescattering of intermediate generic resonances. The bosonic Rho and K(*)-like resonances, produced in initial nucleon-nucleon interactions and materialising only after some delay time, behave like an incompressible fluid with saturated number and energy density.
