The AMPT model
Lin et al, PRC 72, 064901 (2005)
3
The AMPT model
Chen et al.,PLB605,95(2005)
Chen et al.,PRC69,031901(2004)
Good description of light hadron low pT spectra and elliptic flow

Bulk properties in the AMPT model
Equation of state can be characterized by P/ε as a function of ε.
Active particle contributions are evaluated.
• default model hadronizes earlier than the string melting model
• equation of state depends on the parton scattering cross section
