The "Charmed" Plasma Charm quarks have come to the front stage at the Quark Matter 2012 conference that was held in Washington from the 13th to the 18th of August, dedicated to the study of the Quark-Gluon Plasma (QGP). A state of matter present in the early Universe during the first millionths of a second after the Big Bang. In order to recreate such extreme conditions, the worlds most powerful accelerators are used to collide heavy nuclei accelerated at almost light speed. Read more __________________

On 10 November 1974, two experimental groups (one, a MIT group doing experiment on the east coast at Brook-haven National Laboratory, USA and the other a SLAC-Berkeley group doing experiment on the west coast at Stanford Linear accelerator centre, USA) simultaneously announced the discovery of a new particle at 3095 MeV whose lifetime was about 1000 times more than that of other particles of comparable mass.

Charm quarks are found in hadrons, which are subatomic particles made of quarks. Example of hadrons containing charm quarks include the J/psi meson (J/psi), D mesons (D), charmed Read more __________________
