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+ 40 Ar, 63 Cu+ 63 Cu, 96 Ru+ 96 Ru, 197 Au+ 197 Au, and 238 U+ 238 U collisions at s NN = 200 GeV. The yield ratios of deuteron to proton, helium-3 to proton, hypertriton to Λ -hyperon are predicted for various collision systems. In this study, we find the yield ratios between anti-(hyper-)nuclei are significantly suppressed compared to the ratios between the (hyper-)nuclei. It is also interesting to see the strangeness population factor s 3 shows a non-smooth dependence of atomic mass number A around 12 to 27, which can be related to the relative size of the produced nuclei and the emission source of different collision systems. Our present study provides a reference for a upcoming collision system scan program at RHIC. [ABSTRACT FROM AUTHOR]
