This is also true for the study of quantum many-body systems that consist of hyperons (baryons containing strange quarks). In particular, \u039b hyperons form nuclei called \u039b hypernuclei, and are important particles that are also closely related to the structure deep inside neutron stars. However, the interaction between \u039b hyperon and nucleon (\u039bN interaction) is still largely uncertain, and the microscopic understanding of the many-body force (\u039bNN 3-body force) that appears in \u039b hypernuclei and the internal structure of neutron stars remain unsolved issues. In the B02 group, we aim to construct \u039bN, \u03a3N interactions that enables quantitative discussion by promoting (1) measurement of the differential cross section of \u039b hyperon and proton, (2) determination of the strength of the coupling between \u039b and \u03a3 by measuring the cusp that appears at the threshold for the production of \u03a3 hyperon, and (3) derivation of the \u039bN, \u03a3N potential by lattice QCD calculations. We provide this interaction as inputs for the precision calculations of \u039b hypernuclei by the theory group (Group A). &nbsp;This calculation results will be verified by (4) high-resolution spectroscopy of \u039b hypernuclei. By developing precise calculations of \u039b hypernuclei based on the interactions constructed by the B02 group, we will build a foundation for elucidating the \u039bNN three-body force, which is the key to the repulsion of \u039b in neutron stars.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>B02 \u201cElucidation of the forces between baryons through the collaboration of scattering \u00a0experiments and lattic [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":487,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_locale":"en_US","_original_post":"https:\/\/qms.media-creations.org\/?page_id=196","footnotes":""},"class_list":["post-504","page","type-page","status-publish","hentry","en-US"],"_links":{"self":[{"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/pages\/504","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/comments?post=504"}],"version-history":[{"count":5,"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/pages\/504\/revisions"}],"predecessor-version":[{"id":669,"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/pages\/504\/revisions\/669"}],"up":[{"embeddable":true,"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/pages\/487"}],"wp:attachment":[{"href":"https:\/\/qm-science.org\/wp-json\/wp\/v2\/media?parent=504"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
