Predictions for production of \nHΛ3\n and \nH¯Λ¯3\n in isobaric \nRu4496+Ru4496\n and \nZr4096+Zr4096\n collisions at \nsNN=200\n GeV

Abstract

The production of $_{\\mathrm{\\ensuremath{\\Lambda}}}^{3}\\mathrm{H}$ and $_{\\overline{\\mathrm{\\ensuremath{\\Lambda}}}}^{3}\\overline{\\mathrm{H}}$, as well as $^{3}\\mathrm{H}, ^{3}\\overline{\\mathrm{H}}, ^{3}\\mathrm{He}$, and $^{3}\\overline{\\mathrm{H}}\\mathrm{e}$ are studied in central collisions of isobars $_{44}^{96}\\mathrm{Ru}+_{44}^{96}\\mathrm{Ru}$ and $_{40}^{96}\\mathrm{Zr}+_{40}^{96}\\mathrm{Zr}$ at $\\sqrt{{s}_{\\mathrm{NN}}}=200$ GeV, using the dynamically constrained phase-space coalescence model and the paciae model with chiral magnetic effect. The yield, yield ratio, coalescence parameters, and strangeness population factor of (anti-)hypertriton and (anti-)nuclei produced in isobaric $_{44}^{96}\\mathrm{Ru}+_{44}^{96}\\mathrm{Ru}$ and $_{40}^{96}\\mathrm{Zr}+_{40}^{96}\\mathrm{Zr}$ collisions are predicted. The (anti-)hypertriton and (anti-)nuclei production is found to be insensitive to the chiral magnetic effects. Experimental data of $\\text{Cu}+\\text{Cu}, \\text{Au}+\\text{Au,}$ and $\\text{Pb}+\\text{Pb}$ collisions from RHIC, LHC, and the results of the paciae $+$ dcpc model are presented in the results for comparison.
