Title: Recent results from Beam Energy Scan Program at RHIC-STAR experiment – possible signatures from the critical point and the 1^st order phase transition in the QCD phase diagram –
Place: ES635 & ZOOM

Abstract: The Quark Gluon Plasma (QGP) has been studied with high-energy heavy-ion collisions at various experimental facilities in order to investigate the properties of the phase transition and the QCD phase diagram, from the high-temperature phase such as early universe to the high-density phase such as neutron and compact stars, where the first order phase transition and the critical end point are expected towards the high baryon density area in the phase diagram. These phenomena and their possible signatures are being actively searched at Relativistic Heavy-Ion Collider (RHIC) at BNL and several on-going and future facilities. The recent experimental results from the Beam Energy Scan Program (BES-I and BES-II) will be shown and discussed especially focusing on fluctuation, flow and correlation in this presentation, that are related to the first order phase transition and critical end point.
