Physicists present the strongest evidence yet that glueballs—hypothetical particles composed entirely of gluons—may exist in nature. The findings represent a major milestone in particle physics, potentially confirming a long-sought prediction of Quantum Chromodynamics.
Background
Glueballs are hypothetical particles predicted by Quantum Chromodynamics (QCD) that consist purely of gluons, the force carriers of the strong nuclear interaction. Despite decades of search, conclusively detecting them has been notoriously difficult due to their overlap with conventional quark-based mesons.
