Charmed baryons are a category of composite particles comprising all baryons made of at least one charm quark. Since their first observation in the 1970s, a large number of distinct charmed baryon states have been identified. Observed charmed baryons have masses ranging between 2,300 and 2,700 MeV/c2. In 2002, the SELEX collaboration, based at Fermilab published evidence of a doubly charmed baryon (Ξ
cc), containing two charm quarks) with a mass of ~3,520 MeV/c2, but has yet to be confirmed by other experiments. One triply charmed baryon (Ω
ccc) has been predicted but not yet observed.

Famous quotes containing the word charmed:
“At first, he savored only the material quality of the sounds secreted by the instruments. And it had already been a great pleasure when, beneath the tiny line of the violin, slender, resistant, dense and driving, he noticed the mass of the piano’s part seeking to arise in a liquid splashing, polymorphous, undivided, level and clashing like the purple commotion of wave charmed and flattened by the moonlight.”
—Marcel Proust (1871–1922)
