CERN Physicists Have Discovered a Batch of New Exotic Particles

Scientists working at CERN have found four new “tetraquark” particles comprised of the same four subatomic building blocks. These exotic particles don’t last very long, and they probably don’t play an important cosmological role, but the discovery reveals the surprising diversity of the tetraquark family. This isn’t the new fundamental particle that we’re all waiting for, but it’s a fascinating finding nonetheless. Researchers working at the Large Hadron Collider beauty (LHCb) collaboration have confirmed the existence of an entirely new four-quark particle, known as tetraquarks, and three new tetraquarks that had never been seen before. First proposed in 1964 by...

Hopes Are Fading Fast for Possible New Particle at the LHC

Rumors are swirling again among physicists, but this time they’re not about gravitational waves. Instead, hopes are fading that two separate, but complementary, experiments at the Large Hadron Collider may have discovered a possible new particle. Last December, LHC physicists announced that they’d found tantalizing traces of an exotic particle not predicted by the Standard Model of particle physics— perhaps a heavier cousin of the Higgs boson, or the elusive graviton, a quantum carrier of the force of gravity. Neither reported finding was solid enough to claim discovery, but both experiments reported hints of a signal in exactly the same...
