charmed baryon  

Définition

  • 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 2300 and 2700 MeV/c². In 2002, the SELEX collaboration, based at Fermilab published evidence of a doubly charmed baryon (Ξcc), containing two charm quarks) with a mass of ~3520 MeV/c², but has yet to be confirmed by other experiments. One triply charmed baryon (Ωccc) has been predicted but not yet observed. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Charmed_baryon)
