After the collision system almost reaches a local equilibration, the temperature, pressure and energy density are obtained from the phase space information and {$\\eta/s$} is calculated using the Green-Kubo formulas. The results show that {$\\eta$}/$s$ decreases with incident energy and tend towards a smaller value around 0.5, which is not so drastically different from the BNL Relativistic Heavy Ion Collider results in the present model.", "revisions": [ { "version": "v2", "updated": "2011-08-11T01:14:49.000Z" } ], "analyses": { "subjects": [ "66.20.Cy", "25.70.-z" ], "keywords": [ "entropy density ratio", "shear viscosity", "heavy ion collider results", "relativistic heavy ion collider", "boltzmann-uehling-uhlenbeck model" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2011, "month": "Aug", "volume": 84, "number": 2, "pages": "024607" }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "inspire": 918460, "adsabs": "2011PhRvC..84b4607L" } } }
