Description
The existence and the location of the critical end point (CEP) on the QCD phase diagram remains a puzzle. Probing the critical phenomena and locating the CEP are the key goals of the beam energy scan (BES) experiments. When approaching the CEP, the long-range correlation is established, and hence leads to a large fluctuation of the conserved charges. In this presentation, we show, based on the coalescence model and the Landau-Ginzberg theory, that the light nuclei yields and their ratios are enhanced as a consequence of the long-range correlation, which make them ideal probes of criticality [1]. The behavior of the hard probes in the vicinity of the CEP is studied as well [2]. These observables provide us new perspectives for seeking the CEP in the heavy-ion collisions.
