RIKEN Nishina Center for Accelerator-Based Science Theory Group

Group Leader: Yoshitaka Hatta (Ph.D.)

Research Summary

Yoshitaka Hatta (Ph.D.)

RIKEN BNL Research Center has been founded in April 1997 at Brookhaven National Laboratory in the U.S. The center is dedicated to the physics of the Relativistic Heavy-Ion Collider (RHIC), such as spin physics, lattice QCD and Quark-Gluon Plasma (QGP). The theory group conducts world-leading research on the frontiers in RHIC physics. Our main interests include the spin structure of the proton, single-spin asymmetries, the hydrodynamic evolution of the QGP, the QCD phase diagram, jet quenching and the gluon saturation at small-x.
