Two New Exotic Particles Discovered | Science News
Scientists at Jefferson Lab didn’t find the exotic particle they were hunting—but instead uncovered two brand-new, never-before-seen structures in the subatomic world, possibly reshaping how we understand quark combinations. Using photoproduction with a high-energy photon beam, the GlueX Collaboration stumbled upon signals at 2.24 and 1.82 billion electron volts, dubbed Y(2240) and X(1830). These “XYZ states” defy the standard model, offering a tantalizing glimpse into the strange inner workings of matter—and hinting that the particle zoo just got a whole lot weirder and more exciting.
