Analysis of a Double-Λ Hypernucleus Event in the KEK-PS E373 Experiment Khin Than Tint KEK-PS E373, a hybrid emulsion experiment, was performed using a 1.66 GeV/c separated K meson beam at High Energy Accelerator Research Organization (KEK) proton synchrotron (PS). The purpose of this experiment is to study S= -2 nuclei produced via Ξ hyperon captured at rest in nuclear emulsion. We have completed the analysis of about 90% of total emulsion data, among which we have successfully observed seven events of double-Λ hypernucleus and two events of the production of twin Λ-hypernuclei. We succeeded to find the production and the decay of a ΛΛ6 He nucleus. The value of Λ-Λ interaction energy, ΛBΛΛ, for double-Λ hypernucleus event#7 was - 0.5 ± 1.2 MeV which is consistent with the result given by "NAGARA event" (event#2). 2008 http://hdl.handle.net/20.500.12678/0000002006 https://meral.edu.mm/records/2006
