Pre-clustering and light nuclei production close to the QCD critical point

I will discuss some effects of the possible modification of the nucleon-nucleon potential close to QCD critical-end point (CEP). In a simple model of nuclear interactions close to the CEP, we noted that the attraction among nucleons is likely to dominate over repulsion. This would develop sizable nuclear correlations, and possibly the formation of pre-clusters of few nucleons. Therefore, an eventual overproduction of light nuclei compared to thermal expectations is to be expected. I will describe how certain ratios of light nuclei yields can be used to test these effects in heavy-ion collisions. I will also comment on the properties of the Helium 4 nucleus and its excited states, and present some novel nuclear ratios involving this state. I will argue that these could serve as suitable measurements to test the presence of the CEP.
