Studying how these elements form could help scientists understand the interactions among elementary particles in extreme environments such as the interiors of neutron stars or the early universe moments after the Big Bang.<\/p>\n<p>Particles known as \u201cbaryons\u201d\u2014principally protons and neutrons\u2014are composed of three quarks bound tightly together, with their charge depending on the \u201ccolor\u201d of the quarks that make them up. A dibaryon is essentially a system with two baryons. There is one known dibaryon in nature\u2014deuteron, a deuterium (or heavy-hydrogen) nucleus that contains a proton and a <a href=\"https:\/\/phys.org\/tags\/neutron\/\" rel=\"tag\" class=\"\">neutron<\/a> that are very lightly bound. Scientists have long wondered whether there could be other types of dibaryons. Despite searches, no other dibaryon has been found.<\/p>\n<p>The group, in work published in <i>Physical Review Letters<\/i>, has now used powerful theoretical and computational tools to predict the existence of a \u201cmost strange\u201d dibaryon, made up of two \u201cOmega baryons\u201d that contain three strange quarks each. They named it \u201cdi-Omega\u201d. The group also suggested a way to look for these strange <a href=\"https:\/\/phys.org\/tags\/particles\/\" rel=\"tag\" class=\"\">particles<\/a> through experiments with heavy ion collisions planned in Europe and Japan.<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2018-05-scientists-exotic-di-omega-particle.html\">https:\/\/phys.org\/news\/2018&#45;05-scientists-exotic-di-omega-particle.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based Science and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program, together with colleagues from a number of universities, [\u2026]<\/p>\n","protected":false},"author":396,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1523,33,2229,48,1617],"tags":[],"class_list":["post-78967","post","type-post","status-publish","format-standard","hentry","category-computing","category-cosmology","category-mathematics","category-particle-physics","category-quantum-physics"],"_links":{"self":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/78967","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/users\/396"}],"replies":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/comments?post=78967"}],"version-history":[{"count":1,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/78967\/revisions"}],"predecessor-version":[{"id":79021,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/78967\/revisions\/79021"}],"wp:attachment":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/media?parent=78967"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/categories?post=78967"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/tags?post=78967"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
