Recent progress on antimatter and exotic strange particles study at RHIC
Abstract
<p indent="0mm">We introduce the recent progress on antimatter and exotic strange dibaryon study from our group. The main contents include two parts: we measure the interactions between antimatters via antiprotons correlations in relativistic heavy-ion colliders. The results suggest that there is a strong attraction between antiprotons, enough to overcome the Coulomb repulsive force between antiprotons, combined into antimatter nucleus. We measure the interactions between proton-Ω and their antiparticle pairs via two particle correlations to search for a possible p-Ω diabryon. Our results, in comparison with LQCD prediction, slightly favors a proton-Ω bound system with a binding energy of ~<sc>27 MeV.</sc> Our value is much larger than the binding energy of proton and neutron in a deuteron.</p>
