Searching for QCD critical point with light nuclei

Density fluctuations and correlations due to a first-order quark-gluon plasma hadronic matter phase transition its critical end point, if they remain present after the evolution in heavy ion collisions, can lead an enhanced production of light nuclei these collisions. This would then result non-monotonic collision energy dependence yield ratio $$N_\text {t} N_\text {p} / {d}^2$$ proton number {p}$$ , deuteron {d}$$ triton {t}$$ . Measurements this as function thus provides possibility probe equation state strong-interaction diagram.
