We study decay properties of the P-wave charmed baryons using the method of
light-cone QCD sum rules, including the S-wave decays of the flavor
3ˉFP-wave charmed baryons into ground-state charmed baryons
accompanied by a pseudoscalar meson (π or K) or a vector meson (ρ or
K∗), and the S-wave decays of the flavor 6FP-wave charmed
baryons into ground-state charmed baryons accompanied by a pseudoscalar meson
(π or K). We study both two-body and three-body decays which are
kinematically allowed. We find two mixing solutions from internal ρ- and
λ-mode excitations, which can well describe both masses and decay
properties of the Λc(2595), Λc(2625), Ξc(2790) and
Ξc(2815). We also discuss the possible interpretations of P-wave charmed
baryons for the Σc(2800), Ξc(2930), Ξc(2980), and the
recently observed Ωc(3000), Ωc(3050), Ωc(3066),
Ωc(3090), and Ωc(3119).Comment: 44 pages, 9 figures. Version appears in Phys. Rev.
