One of the key puzzles is to figure out why there is so much more matter than antimatter in the Universe, regarded as the CP asymmetry. The \u039e hyperon with strangeness S=\u22122, sometimes so-called the doubly-strange baryon, can provide key information to probe the asymmetry of the matter and antimatter. In this review, we discuss the studies of CP asymmetry in \u039e hyperon decay at E756, HyperCP and BESIII experiments.<\/jats:p>","DOI":"10.3390\/sym15010214","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T02:28:44Z","timestamp":1673490524000},"page":"214","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["CP Asymmetry in the \u039e Hyperon Sector"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0271-2311","authenticated-orcid":false,"given":"Hao","family":"Liu","sequence":"first","affiliation":[{"name":"School of Physical Science and Technology, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9567-7094","authenticated-orcid":false,"given":"Jingxu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8612-8045","authenticated-orcid":false,"given":"Xiongfei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Lanzhou University, Lanzhou 730000, China"},{"name":"Lanzhou Center for Theoretical Physics, Key Laboratory of Theoretical Physics of Gansu Province and Frontiers Science Center for Rare Isotopes, Lanzhou University, Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1103\/RevModPhys.76.1","article-title":"The Origin of the matter-antimatter asymmetry","volume":"76","author":"Dine","year":"2003","journal-title":"Rev.
