Abstract

In this work, the parton and hadron cascade model (PACIAE) and the dynamically constrained phase space coalescence model (DCPC) are used to investigate the production of hypertriton and antihypertriton in Pb-Pb collisions at , 2.76, 5.02 and 7 TeV. The model parameters are fixed by comparing the PACIAE result with ALICE data on Λ and p productions in Pb-Pb collisions at TeV. Then, the predetermined parameters are used in PACIAE and DCPC models to simulate the hypertriton production in Pb-Pb collisions at TeV. The hypertriton and antihypertriton yields in Pb-Pb collisions at , 5.02 and 7 TeV are predicted in this work.
