Title: 40th HENPIC Seminar: Discussion on the Hypertriton lifetime measurements

Abstract:Hypernuclei is composed of nucleon, proton and hyperon, thus becomes the ideal micro-lab to understand the hyperon-nucleon (YN) interaction. The YN interaction, responsible in part for the binding of hyper nuclei, is of fundamental interest in nuclear physics and nuclear astrophysics. In this talk, I will start from a breif review of the early measurements on hyertriton lifetime from independent experiment. I will focus on the recent pcise results from the Relativistic Heavy-Ion Collider at BNL. A comparison with the similar measurements from GSI-HypHI fixed target exp. and the LHC-ALICE will also be made. Physics implications on the YN interaction and the consequence on the light hyper nuclei structure will be discussed.
