Abstract: Locating the possible critical (end-)point (CEP), characterized by a diverging density-density correlation length, in the phase diagram of Quantum Chromodynamics (QCD) through the Beam Energy Scan (BES) program at RHIC is one of the main goals in high-energy nuclear physics. Besides the non-Gaussian fluctuation of net-protons, the light nuclei production has long been suggested as a good observable. In this talk, I will discuss different production mechanisms of light clusters in high-energy nucleus collisions. In particular, I will present our recent progress about the QCD criticality on light nuclei production. Moreover, I will discuss the effects of first-order QCD phase transition on the light nuclei production within a transport approach. Our results suggest that the non-monotonic behavior of the yield ratio tp/d^2 in its collision energy dependence is closely related to the non-smooth QCD phase transitions, therefore, it can be used to locate the critical point in QCD phase diagram in relativistic heavy-ion collisions.
