systematically varying the amount of energy involved in collisions of gold nuclei, scientists have shown that the quark-gluon plasma (QGP) exists in collisions at energies from 200 billion electron volts (GeV) at least to 19.6 GeV. However, its production appears to be “turned off” at the lowest collision energy, 3 GeV. The “off” signal shows up as a sign change in data that describe the distribution of protons produced in these collisions. The findings will help physicists further study the QGP and phases of nuclear matter.
