Recent heavy-ion collision experiments reported a surprisingly short lifetime for the hypertriton, which has been recognized as the hypertriton lifetime puzzle. Our J-PARC E73 experiment contributes to solve this puzzle with an independent experimental method by employing
3 He(K− , π0 )3 Λ H reaction. In this contribution, we will demonstrate our capability to provide3 Λ H binding energy information by deriving the production cross section ratio, σ /σ3 Λ H . The production cross section data for4 Λ H3 Λ H and4 Λ H are already available as the pilot run of E73 experiment and data analysis is in progress. [ABSTRACT FROM AUTHOR]- Published
