This thesis reports the first indications of the Λ(1520) and ∆(1232)++ decay modes in the Ξc0 → pK−K−π+ decay. The obtained fractions relative the inclusive Ξc0 → pK−K−π+ decay are (6.4±0.6)% and (32.6±1.2)% for the decays through the Λ(1520) and ∆(1232)++ resonances respectively. The estimates were done on a sample of 6449±226 events of the Ξc0 baryon originating in the pure hadron Ξb− → Ξc0π− decay. The fractions presented in this thesis should be seen as an early indication rather than final estimates as more in-depth studies need to be done.
