From relativistic heavy ion collision to antimatter production

Relativistic heavy ion collider provides a unique venue to form a new kind of matter, namely the quark-gluon plasma, and while abundant antimatter could be produced. At BNL-Relativistic Heavy-Ion Collider (RHIC), head-on collisions of gold ions moving at nearly the speed of light simulate the conditions of a plasma of the smallest components of matter — the quarks and gluons. Abundant antinucleons can be produced after cooling down of the quark-gluon plasma that has the excellent capability of conducting the hunt of antimatter nuclei and studying interaction between antiprotons. In this talk, I will give overview of quark gluon plasma as well as antimatter nuclei production at RHIC
