Charmed baryons

（重定向自Charmed baryon）

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 7003230000000000000♠2300 and 7003270000000000000♠2700 MeV/c. 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 ~7003352000000000000♠3520 MeV/c, but has yet to be confirmed by other experiments. One triply charmed baryon (Ω
ccc) has been predicted but not yet observed.
