Heavy baryons in the relativized quark model with chromodynamics

Following the work of Capstick and Isgur [{https://doi.org/10.1103/PhysRevD.34.2809}{Phys.~Rev.~D~34,~2809~(1986)}], we systematically study the mass spectrum of the heavy baryons in the relativized quark potential model with chromodynamics. Besides the original Godfrey-Isgur (GI) model, we also adopt a modified GI model which replaces the linear confinement by a screened one. The two models give similar results in our work. All heavy baryons observed so far can be explained as three-quark states. In particular, we identify the Ωc(3000)/Ωb(6316), Ωc(3050)/Ωb(6330), Ωc(3065)/Ωb(6340) and Ωc(3090)/Ωb(6350) states as the pλ excitations with quantum numbers 1/2⁻, 3/2⁻, 3/2⁻ and 5/2⁻. The Ωc(3120) is a 3/2⁻ state with the pρ excitation, whose bottom partner is predicted to be Ωb(6446/6457,3/2⁻). The higher state Ωc(3188) is the 2sλ excitation with quantum numbers 1/2⁺, and Ωc(3327) is a dλ excitation with quantum numbers 3/2⁺ or 5/2⁺. In addition, the Λc(2940) with quantum numbers JP=3/2⁻ could be explained as the pρ excitation.
