The emission order of hydrogen isotopes via correlation functions in 30 MeV/u Ar+Au reactions

Simulations of momentum correlation functions of light (anti)nuclei in relativistic heavy-ion collisions at $\sqrt{s_{NN}}$ = 39 GeV

“…We further study centrality and system-size dependence of momentum correlation functions for identical and nonidentical light (anti)nuclei pairs, respectively, which is in the condition of the maximum hadronic rescattering time of 100 f m/c in AMPT. The shape of momentum correlation functions for light (anti)nuclei pairs is consistent with previous works [13,30,36,37,79,80], which is caused by both QS and FSI. The similar structure between light nuclei momentum correlation functions and anti-ones indicates that the interaction between them are the same, which has been confirmed in Ref.…”

“…The correlation functions of p-t and d-t in Fig. 4 (c) and (e) also display the trend of below unity due to the dominant Coulomb repulsion, which is similar to the previous results in intermediate energy heavy-ion collisions [36,37]. In Fig.…”

“…The similar trend for d-t pairs is not so obvious overall, except for in peripheral collision the momentum correlation function with v d < v t is stronger and deuterons are emitted averagely earlier than tritons. In contrast with the emission order as shown in many previous results of the intermediate energy heavy-ion collisions [12,36,37,81], the average emission sequence of protons, deuterons, and tritons is opposite for 39 GeV heavy-ion collisions. Meanwile, Fig.…”

“…For the p-d (p-d) momentum correlation functions in Fig. 5 (a), the anticorrelation shape is a little unlike to the proton−deuteron momentum correlation function in the intermediate energy heavy-ion collision [36,37], indicating that a competition between the s-wave attraction and the Coulomb repulsion. The correlation functions of p-t and d-t in Fig.…”

“…[34]. Theoretical study has been extended to different kinds of nonidentical particle pairs, for instance p-d, n-p [35][36][37][38], π-p [39], K + -K − [40], d-t [12,22] as well as 3 He-α particles [41] in intermediate energy HICs.…”
