Zusammenfassung:We study two- and three-baryon systems with two units of charm looking for possible bound states or resonances. All two-baryon interactions are consistently derived from a constituent quark model tuned in the light-flavor hadron phenomenology: spectra and interactions. The presence of the heavy quarks makes the two-body interactions simpler than in the light-flavor sector. Our results show a narrow two-body resonance with quantum numbers ( I , J P ) = ( 0 , 0 + ) . It is located 6.2 MeV below the Σ c Σ c threshold and has a width of 4.7 MeV. The foregoing two-body state contributes to generate a N Σ c Σ c resonance with quantum numbers ( I , J P ) = ( 1 / 2 , 1 / 2 + ) and a separation energy of 0.2 MeV.
