Hadronic Transport Model Study of Elliptic Flow in ~(197)Au + ~(197)Au Collisions at (S_(NN))~1/2 = 200 GeV

摘要

1. RQMD under predicts the absolute of the v2, due to lack of the hot and dense partonic interaction in the model 2. Low pt region: hadron mass dependence observed via rescatterings! 3. Intermediate pt region: hadron type dependence observed, due to the vacuum hadronic cross sections used in hadronic model → the NCQ-scaling also observed in hadronic transport model. Coalescence explanation may not be unique! 4. High precision data on v2 of K~*, ρ, Φ, Λ~*, Ξ~* are important!
