Among these, the identification of the Ξ− hyperon was performed with the constant sagitta (CS) method, by measuring multiple Coulomb scattering for 695 clear stopping events, σ-stop, with emission of nuclear fragments due to negatively charged hadrons. With use of a Geant4 simulation, the parameters for the CS method were optimized and we obtained the number of real Ξ− stopping events to be 432.3±7.6+ 0.0−14.0 with 3.2% systematic error by contamination by the Σ− hyperon. We have classified the events for Ξ− hyperon capture by light (C, N, O) and heavy (Ag, Br) elements in the emulsion. The trapping probabilities of two Λ hyperons for light and heavy nuclei were found to be 5.0±1.7% and 4.2±1.4%⁠, respectively, for σ-stop via Ξ− hyperon capture at rest in the emulsion. For at least one Λ trapping, the probabilities were 69.4±8.1% for light nuclei and 51.1±5.7% for heavy nuclei. These results allow us to present the trapping probabilities of Λ hyperons via Ξ− hyperon capture at rest in emulsion for the first time, because the previous E176 experiment showed the lower limits due to fewer statistics."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Trapping probability"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-05-05"}],"displaytype":"preview","filename":"Trapping probability of strangeness via Xi−.pdf","filesize":[{"value":"3518 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/728/files/Trapping probability of strangeness via Xi−.pdf"},"version_id":"83a5c6a2-0773-4e02-8f87-e72bd70825a6"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"2","subitem_journal_title":"Progress of Theoretical and Experimental Physics,021D01","subitem_volume":"2019"}]},"item_1583103147082":{"attribute_name":"Conference papaers","attribute_value_mlt":[{}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_supervisor(s)":[]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Aye Moh Moh Theint"},{"subitem_authors_fullname":"Ekawa, Hiroyuki"},{"subitem_authors_fullname":"Kasagi, Ayumi"},{"subitem_authors_fullname":"Kinbara, Shinji"},{"subitem_authors_fullname":"May Sweet"},{"subitem_authors_fullname":"Khin Than Tint"},{"subitem_authors_fullname":"Yoon, Chun Sil"},{"subitem_authors_fullname":"Yoshida, Junya"},{"subitem_authors_fullname":"Yoshimoto, Masahiro"},{"subitem_authors_fullname":"Nakazawa, Kazuma"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2019"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"https://umoar.mu.edu.mm/handle/123456789/382"},"item_title":"Trapping probability of strangeness via Xi− hyperon capture at rest in nuclear emulsion","item_type_id":"21","owner":"1","path":["1582967025340"],"publish_date":"2020-03-05","publish_status":"0","recid":"728","relation_version_is_last":true,"title":["Trapping probability of strangeness via Xi− hyperon capture at rest in nuclear emulsion"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T04:59:51.521981+00:00"}
