The production of HΛ3 and H¯Λ¯3 , as well as H3, H¯3, He3 , and H¯e3 are studied in central collisions of isobars Ru4496+Ru4496 and Zr4096+Zr4096 at sNN=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 Ru4496+Ru4496 and Zr4096+Zr4096 collisions are predicted. The (anti-)hypertriton and (anti-)nuclei production is found to be ...
