英文摘要 | We study the P-wave charmed baryons using the method of QCD sum rule in the framework of heavy quark effective theory. We consider systematically all possible baryon currents with a derivative for internal rho- and lambda-mode excitations. We have found a good working window for the currents corresponding to the rho- mode excitations for A(c) (2595), A(c) (2625), Xi(c) (2790), and Xi(c) (2815) that complete two SU(3) (3) over barF multiplets of J(P) = 1/2(-) and 3/2(-), while the currents corresponding to the lambda-mode excitations seem also consistent with the data. Our results also suggest that there are two Sigma(c) (2800 states of J(P) = 1/2(-) and 3/2(-) whose mass splitting is 14 +/- 7 MeV, and two Xi(c) (2980) states whose mass splitting is 12 +/- 7 MeV. They have two Omega(c) partners of J(P) = 1/2(-) and 3/2(-), whose masses are around 3.25 +/- 0.20 GeV with mass splitting 10 +/- 6 MeV. All of them together complete two SU (3) 6(F) multiplets of J(P) = 1/2(-) and 3/2(-). They may also have J(P) = 5/2(-) partners. Xi(c) (3080) may be one of them, and the other two are Sigma(c) (5/2(-) ) and Omega(c) (5/2(-)), whose masses are 85 +/- 23 MeV and 50 +/- 27 MeV larger. |
