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 (3) over bar (F) P-wave charmed baryons into ground-state charmed baryons accompanied by a pseudoscalar meson (pi or K) or a vector meson (rho or K*), and the S-wave decays of the flavor 6(F) P-wave charmed baryons into ground-state charmed baryons accompanied by a pseudoscalar meson (pi or K). We study both two-body and three-body decays which are kinematically allowed. We find two mixing solutions from internal rho- and lambda-mode excitations, which can well describe both masses and decay properties of the Lambda(c) (2595), Lambda(c)(2625) Xi(c)(2790) and Xi(c)(2815). We also discuss the possible interpretations of P-wave charmed baryons for the Sigma(c)(2800), Xi(c)(2930), Xi(c)(2980), and the recently observed Omega(c)(3000), Omega(c)(3050), Omega(c)(3066), Omega(c)(3090), and Omega(c)(3119).
