Precise lifetime measurement of Λ4H hypernucleus using in-flight 4He(K−,π0)Λ4H reaction

We present a new measurement of the Λ4H hypernuclear lifetime using in-flight K− + 4He → Λ4H + π0 reaction at the J-PARC hadron facility. We demonstrate, for the first time, the effective selection of the hypernuclear bound state using only the γ-ray energy decayed from π0. This opens the possibilit...
