What to know

  • RHIC scientists detected quark-gluon plasma—primordial matter from the Big Bang—in oxygen collisions at substantially lower energies than previously known to produce it.
  • Jet quenching (high-energy particles losing energy in the collision material) confirmed the plasma's formation in these smaller collision systems.
  • The findings narrow the boundaries of conditions needed to create early-universe matter, challenging existing physics models of plasma formation.

“This analysis is pushing the boundaries to an extreme case to help us learn something about this jet quenching phenomenon and the conditions needed to generate a QGP.”

    STAR experiment detects quark-gluon plasma in low-energy oxygen collisions

    Researchers at the RHIC found strong evidence of quark-gluon plasma (QGP) formed by colliding oxygen nuclei at nearly the speed of light at substantially lower energies than previously known to produce such matter. The detection was confirmed through jet quenching—high-energy particles losing energy as they travel through the collision material.

    “The QGP is believed to be the form of matter that filled the early universe — before the protons and neutrons that make up today's atoms formed.”
