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 − , π 0 ) 3 Λ H reaction. In this contribution, we will demonstrate our capability to provide 3 Λ H binding energy information by deriving the production cross section ratio, σ 3 Λ H / σ 4 Λ H . The production cross section data for 3 Λ H and 4 Λ H are already available as the pilot run of E73 experiment and data analysis is in progress.
