 | | The existence of the gauge bosons that carry this force, the W and Z particles, was confirmed in 1983 at CERN, the European nuclear research organization. |
 | | In 2003 scientists at the High-Energy Accelerator Research Organization in Tsukuba, Japan, discovered a new particle that could not be explained in terms of existing theories of energy and matter. |
 | | The unknown particle, which the researchers classified as X(3872), was detected in the decay products of beauty meson particles; it weighed as much as a single atom of helium and lasted a billionth of a trillionth of a second, an unusually long lifetime for a subatomic particle of this size. |
