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 ...

The strong interaction is one of the fundamental forces of nature, which binds quarks into hadrons such as the proton and the neutron, the building blocks of atoms. According to the quark model, ...

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 ...

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 ...
