Observation of the doubly charmed baryon Ξcc++.

Abstract:

A highly significant structure is observed in the Λ+cK−π+π+ mass spectrum, where the Λ+c baryon is reconstructed in the decay mode pK−π+. The structure is consistent with originating from a weakly decaying particle, identified as the doubly charmed baryon Ξ++cc. The difference between the masses of the Ξ++cc and Λ+c states is measured to be 1334.94±0.72(stat.)±0.27(syst.)  MeV/c^2, and the Ξ++cc mass is then determined to be 3621.40±0.72(stat.)±0.27(syst.)±0.14(Λ+c)  MeV/c^2, where the last u...
