The physics interest of the LBL Soft Physics Group is to study the formation and characteristics of the medium system created in relativistic nucleus-nucleus collisions at RHIC energies, with focus on the single particle momentum spectra, azimuthal anisotropic distributions, two particle correlations, heavy flavor and electromagetic probe production by utilizing the STAR detector. We are studying/searching for the MATTER EoS with partonic degrees of freedom: partonic collectivity, thermalization, and the temperature of the system created at RHIC. We are also carrying out the program of exploring the QCD phase map to search for the first order phase transition boundary and the possible QCD critical point.
