# Nuclear correlations, pre-clusters and light
nuclei close to the QCD critical point

## Juan Torres-Rincon

I will discuss several effects of the
possible modification of the nucleon-nucleon potential close to QCD
critical-end point (CEP). In a simplified model of the nuclear interaction
close to the CEP, we noted that the attraction is likely to dominate over
repulsion. This would develop important nuclear correlations, and perhaps
the formation of pre-clusters of few nucleons with the eventual
overproduction of light nuclei compared to the thermal expectations. Some
nuclear ratios are proposed to test this effect in heavy-ion collisions. I
will comment on the quantum effects of these systems using two approaches:
the semiclassical thermal flucton, and the solution of the SchrÃ¶dinger
equation. Finally I will describe the case of Helium 4 and its ca. 50
excited states, which are expected to feed-down lighter nuclei, what can
have some relevance for intermediate- and low-energy ion collisions.
