This particle has an unusually long lifetime of approximately 10^-20 s and a very narrow decay width of 3 keV, both of which are explained by the (*) OZI rule.
The production of this particle is enhanced in the deconfined QGP phase, which has allowed scientists at the Large Hadron Collider to use the observation of this particle as evidence for deconfinement. Its discovery was preceded by the work of Glashow, Iliopoulos, and Maiani, formulators the GIM mechanism which predicted the existence of the particles that compose it. This particle has an unusually long lifetime of approximately 10^-20 s and a very narrow decay width of 3 keV, both of which are explained by the (*) OZI rule. Discovered during the November Revolution, it won the Nobel prize for Samuel Ting and Burton Richter, two scientists who discovered it independently and each contributed one letter to this particle's name. For 10 points, name this simplest charmonium bound state consisting of a charm quark and charm antiquark, a certain meson with a two-letter name.
