AI Summary

Scientists analyzing data from the STAR detector at the Relativistic Heavy Ion Collider observed a pronounced dip in momentum‑fluctuation measurements taken from gold‑nucleus collisions. The dip occurs in a sparsely studied sector of the nuclear phase diagram, specifically at the collider’s lowest collision energies where the resulting matter reaches its highest density. This pattern suggests potentially novel behavior in dense nuclear matter. The results are reported in a new paper published in Physical Review Letters.
