Production of multistrange hadrons, light nuclei and hypertriton in central Au+Au collisions at sNN=11.5 and 200 GeV

The production of dibaryons, light nuclei and hypertriton in the most central Au+Au collisions at sNN=11.5 and 200 GeV is 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 sNN=11.5(200) GeV. The pTpT integrated yield of multistrange hadrons falls exponentially as strangeness quantum number increases. We further investigate strangeness population factors S3,S2S3,S2 as a function of transverse momentum as well as sNN. The calculations for sNN=11.5 GeV presented here will stimulate interest to carry out these measurements during the phase-II of beam energy scan program at STAR experiment.
