For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

Newly released observations of the top quark -- the heaviest of all known fundamental particles -- could topple the standard model of particle physics. Data from collisions at the Tevatron particle ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...
