We review recent results from the RHIC beam energy scan (BES) program, aimedto study the Quantum Chromodynamics (QCD) phase diagram. The main goals are tosearch for the possible phase boundary, softening of equation of state or firstorder phase transition, and possible critical point. Phase-I of the BES programhas recently concluded with data collection for Au+Au collisions atcenter-of-mass energies ($\sqrt{s_{NN}}$) of 7.7, 11.5, 19.6, 27, and 39 GeV.Several interesting results are observed for these lower energies where thenet-baryon density is high at the mid-rapidity. These results indicate that thematter formed at lower energies (7.7 and 11.5 GeV) is hadron dominated andmight not have undergone a phase transition. In addition, the centralitydependence of freeze-out parameters is observed for the first time at lowerenergies, slope of directed flow for (net)-protons measured versus rapidityshows an interesting behavior at lower energies, and higher moments ofnet-proton show deviation from Skellam expectations at lower energies. Anoutlook for the future BES Phase-II program is presented and efforts for thedetailed study of QCD phase diagram are discussed.
