Lifetime measurement of Λ4H hypernucleus
Description
Results are reported on a lifetime measurement of Λ4H formed in 4He (stopped K-, π0) reaction. Decay of Λ4H was clearly identified by observing the monochromatic π0 peak from two-body decay (Λ4H → 4He + π- pπ = 132.9 MeV/c). The lifetime of Λ4H was determined to be τ(Λ4H) = 194-26+24 ps from a distribution of time difference between the K- injection and π- emission. (author)
