Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Newly discovered particles have incited a fierce debate among experts about the correct picture of matter at the quantum scale. In August 2003, an experiment at the KEKB particle accelerator in Japan ...

Since the spectacular discovery of the Higgs boson in 2012, physicists at the Large Hadron Collider (LHC), the gigantic particle accelerator outside Geneva, have suffered a bit of a drought when it ...

This spring, at a meeting of Syracuse University’s quark physics group, Ivan Polyakov announced that he had uncovered the fingerprints of a semi-mythical particle. “We said, ‘This is impossible. What ...

One of the most important observations in particle physics was the discovery in 1964 of the Omega-minus baryon at Brookhaven National Laboratory. In the two decades leading up to this point over 27 ...
