Partonic Equation of State in Relativistic Heavy Ion Collisions
The goal of the RHIC and the future LHC programs is to identify and study the matter with partonic degrees of freedom and determine the phase structure of the QCD phase diagram [1, 2]. In high-energy nuclear collisions, due to large initial density and frequent re-scatterings, collective motion develop [3]. Depends on both the duration and the strength of the frequent scatterings, local thermal...
متن کاملDirect Photons from Relativistic Heavy-Ion Collisions
Direct photons have been proposed as a promising signature for the quark-gluon plasma (QGP) formation in relativistic heavy-ion collisions. Recently WA98 presented the first data on direct photons in Pb+Pb-collisions at SPS. At the same time RHIC started with its experimental program. The discovery of the QGP in these experiments relies on a comparison of data with theoretical predictions for Q...
متن کاملExcitation Function of Energy Density and Partonic Degrees of Freedom in Relativistic Heavy Ion Collisions
We estimate the energy density ǫ pile-up at mid-rapidity in central Pb+Pb collisions from 2 – 200 GeV/nucleon. ǫ is decomposed into hadronic and partonic contributions. A detailed analysis of the collision dynamics in the framework of a microscopic transport model shows the importance of partonic degrees of freedom and rescattering of leading (di)quarks in the early phase of the reaction for El...
متن کاملComment on Transverse Mass Dependence of Partonic Dilepton Production in Ultra-relativistic Heavy Ion Collisions
Response to a recent Comment by M. Asakawa concerning scale-breaking effects in dilepton emission from partons in pre-equilibrium and quark-gluon plasma during the early stage of ultra-relativistic heavy ion collisions. PACS Indices: 12.38 Mh, 25.75.+r, 24.85.+p, 13.87.Fh In a recent paper M. Asakawa [1] commented a previous letter [2] on M⊥-dependence of dilepton emission [3] calculated with i...
