{"arxiv_id":"hep-ph/0403234","title":"Prethermalization","abstract":"Prethermalization of the equation of state and the kinetic temperature to their equilibrium values occurs on time scales dramatically shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collisions of heavy nuclei or other nonequilibrium phenomena in complex quantum and classical many body systems. We also compare the chemical equilibration time with other characteristic time scales.","primary_cat":"hep-ph","cross_cats":["cond-mat.other","hep-th","nucl-th"],"submitted_at":"2004-03-22T13:15:33+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"In a two-loop 2PI simulation of a quark-meson model, the equation of state and a global kinetic temperature reach near-equilibrium values within about one inverse thermal mass, roughly a hundred times faster than full thermal equilibration.","novelty_score":6.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":24,"_links":{"html":"https://pith.science/paper/hep-ph/0403234","verdict":"/api/v1/verdicts/hep-ph/0403234"}}
