Abstract
We report preliminary results on HΛ3 production in Au + Au collisions at RHIC at sNN=7.7, 11.5, 19.6, 27, 39, and 200 GeV. The beam energy dependence of strangeness population factor HΛ3/3HeΛ/p is shown and the result indicates that HΛ3/3HeΛ/p has an increasing trend with 1.7σ significance. The hypertriton lifetime combining the above Au + Au collision data set is measured to be 123±2226(stat)±10(sys) ps.
