Effects of QCD critical point on light nuclei production

Using the nucleon coalescence model, which can naturally take into account correlations in density distribution, we study effects of QCD critical point on light nuclei production relativistic heavy-ion collisions. We find that yield ratio NtNp/Nd2 proton (p), deuteron (d) and triton (t) increases monotonically with correlation length, is expected to increase significantly near phase diagram. Our thus demonstrates be used as a sensitive probe phenomenon. further discuss relation between transitions collisions possible non-monotonic behavior its collision energy dependence.
