Description
Strange hadron productions are sensitive probes to the dynamics of the hot and
dense matter created in heavy-ion collisions. In this talk, we will present the recent
STAR measurements on the production of various strange hadrons (K0s, phi, Lambda,
Xi and Omega) in $\sqrt{S_{NN}}$ = 7.7 - 39 GeV Au+Au collisions in the STAR beam
energy scan program. We will investigate the collision energy dependence of the
strangeness enhancement, nuclear modification factors, baryon to meson ratios,
as well as the phi meson elliptic flow. We will present the extracted chemical and
kinetic freeze-out parameters with the thermal and blast wave models as a function
of energy and centrality. The physics implications of these measurements on the
collision dynamics will be discussed.
