RHIC data reveal intriguing dip in momentum fluctuations in high-density nuclear matter

Scientists using the STAR detector at the Relativistic Heavy Ion Collider found an intriguing dip in collision-by-collision momentum fluctuations from gold nuclei collisions at RHIC's lowest energies. The anomaly may signal new physics in the highest-density region of the nuclear phase diagram.
