Enhanced yield ratio of light nuclei in heavy ion collisions with a first-order chiral phase transition

Using a transport model that includes first-order chiral phase transition between the partonic and hadronic matter, we study development of density fluctuations in matter produced heavy ion collisions as it undergoes transition, their time evolution later stage collisions. coalescence to describe production deuterons tritons from nucleons at kinetic freeze out, find yield ratio $ N_\text{t}N_\text{p}/ N_\text{d}^2$, where $N_\text{p}$, $N_\text{d}$, $N_\text{t}$ are, respectively, proton, deuteron, triton numbers, is enhanced if trajectory QCD diagram passes through spinodal region transition.
