Observation of the Antimatter Nuclei in Relativistic Heavy Ion Collisions

Recently antimatter hyper-triton nuclei ${(_{bar{Lambda}}^3bar{H})}$ and antimatter helium nuclei ${(_2^4bar{He})}$ are discovered with the Solenoidal Tracker At Rhic detector in relativistic heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) (STAR Collaboration in Science 328(5974):58–62, 2010; STAR Collaboration in Nature 473:353–356, 2011). In this presentation, discoveries of antimatter particle are historically scanned and the recent observations at RHIC are reported in details as well as potential possibilities of discovery of antimatter nuclei at ALICE.
