摘要
Based on the extended hadronic transport model,we investigate the incompressibility of dense hadronic matter formed in relativistic Au+Au heavy-ion collisions at√SNN=3 GeV.By comparing various experimental observ-ables,such as proton directed ow,production yields of strange hadronsϕ,K−as well as their ratioϕ/K−and proton high-order cumulants with our model calculations,we nd that hadronic interactions play a dominant role in these collisions.
