Collision system size dependence of light (anti-)nuclei and (anti-)hypertriton production in high energy nuclear collisions
The collision system size dependence of light (anti-)nuclei and (anti-)hypertriton production is investigated using the parton and hadron cascade (PACIAE) model plus dynamically constrained phase-space coalescence (DCPC) model in 10 B+ 10 B, 12 C+ 12 C, 16 O+ 16 O, 20 Ne+ 20 Ne, 27 Al+ 27 Al, 40 Ar+...
