RIKEN Nishina Center for Accelerator-Based Science RHIC Physics Research Laboratory
Director: Robert Tribble (Ph.D.)
Research Summary

We study the strong interaction using RHIC collider at Brookhaven National Laboratory, USA. RHIC can collide heavy nuclei at high energy, producing hot and high density matter called Quark Gluon Plasma, which existed in early Universe. We study the properties of QGP produced at RHIC. We also study the nucleon structure with polarized pp collisions at RHIC. Polarized proton collisions at RHIC were realized at the initiative of RIKEN. we built a silicon tracking detector INTT for the new sPHENIX experiment. sPHENIX has started experiments in 2024.
