摘要：

Hypernuclei are bound states of nucleons and at least one hyperon. In particular, the hypertriton H-3(Lambda), a bound state consisting of a proton, neutron and hyperon, is the lightest known hypernucleus. Precise measurements on the energy dependence of H-3(Lambda) production will give invaluable information on hypernuclei production mechanisms due to its unique intrinsic properties. The second phase of the Beam Energy Scan (BES-II) at RHIC provides a great opportunity to study hypernuclei production. In these proceedings, we present p(T)-integrated yields (dN/dy) at mid-rapidity, yield ratios and average transverse momentum (< pT >) of H-3(Lambda) as a function of collision energy in Au+Au collisions from root s(NN) = 3 to 27 GeV. These results are compared with phenomenological model calculations, and physics implications on production mechanism are discussed.
