Predictions for production of HΛ3 and H¯Λ¯3 in isobaric Ru4496+Ru4496 and Zr4096+Zr4096 collisions at sNN=200 GeV

Abstract

The production of $\rm{^3_\Lambda H}$ and $\rm{{^3_{\overline \Lambda}\overline H}}$, as well as $\rm{^3H}$, $\rm{{^3\overline H}}$, $\rm{^3He}$, and $\rm{{^3\overline {He}}}$ are studied in central collisions of isobars $^{96}_{44}$Ru+$^{96}_{44}$Ru and $^{96}_{40}$Zr+$^{96}_{40}$Zr at $\sqrt{s_{\rm{NN}}}=200$ GeV, using the dynamically constrained phase-space coalescence model and the {\footnotesize 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 $^{96}_{44}$Ru+$^{96}_{44}$Ru and $^{96}_{40}$Zr+$^{96}_{40}$Zr collisions are predicted. The (anti-)hypertriton and (anti-)nuclei production is found to be insensitive to the chiral magnetic effects. Experimental data of Cu+Cu, Au+Au and Pb+Pb collisions from RHIC, LHC, and the results of {\footnotesize PACIAE+DCPC} model are presented in the results for comparison.
