报告摘要：The lifetimes of light hypernuclei, particularly the hypertriton ^3_Lambda H, have been subjects of intense study due to conflicting measurements from recent heavy-ion collision experiments. Some measurements report lifetimes significantly shorter than the free Lambda lifetime (HypHI 2013, STAR 2018 and ALICE 2016), while others find consistency with it (STAR 2021 and ALICE 2023). To address this discrepancy, our J-PARC E73 experiment employs the K^-, pion^0) strangeness exchange reaction with a high-intensity $K^-$ beam at the J-PARC K1.8 beam line, enabling direct lifetime measurements of both ^3_Lambda H and ^4_Lambda H hypernuclei in the time domain.
