RIKEN Nishina Center for Accelerator-Based Science RIKEN BNL Research Center

RBRC Director: Robert Tribble (Ph.D.)

Research Summary

Hideto  Enyo

The RIKEN BNL Research Center was established in April 1997 at Brookhaven National Laboratory. The Center is dedicated to the study of strong interactions, including spin physics, lattice QCD and RHIC physics through the nurturing of a new generation of young physicists. The Center has three research groups: Theory Group led by Y.Hatta, Experimental Group led by Y. Akiba, and Computing Group led by T. Izubuchi. In addition to the strong research program in these three groups, we have a joint-fellowship program with other Universities. The fellowship program enables a talented researcher to maintain a tenure track position at his/her university as well as a Fellow position at RBRC for a certain period of time.
