Production of multistrange hadrons, light nuclei and hypertriton in central Au+Au collisions at $\sqrt{s_{NN}}=$ 11.5 and 200 GeV

Understand

The production of dibaryons, light nuclei and hypertriton in the most central Au+Au collisions at $\sqrt{s_{NN}}=$ 11.5 and 200 GeV are investigated by using a naive coalescence model.

• The production of light nuclei is studied and found that the production rate reduces by a factor of 330 (1200) for each extra nucleon added to nuclei at $\sqrt{s_{NN}}=$ 11.5 (200) GeV.
• The $p_{T}$ integrated yield of multistrange hadrons falls exponentially as strangeness quantum number increases.
• We further investigate strangeness population factor $S_{3}, S_{2}$ as a function of transverse momentum as well as $\sqrt{s_{NN}}$.
