Abstract:
The LHCb Collaboration recently observed five narrow Ωc0 resonances, and measured their masses and widths through the decays Ωc0 → Ξc+K. Motivated by this discovery, and also by the fact that the ground-state bottom baryon Ωb with spin-1/2 was already found experimentally, we perform theoretical investigation of the spin-1/2 and spin-3/2, Ωb, baryons by calculating decay width of their first orbitally and radially excited states to Ξb0 K. For this purpose, we employ QCD sum rule method on the light-cone by including into analysis the K meson distribution amplitudes up to twist-4. Obtained analytical expressions are utilized to extract parameters of these decay processes which may be useful for forthcoming experimental studies of bottom baryons.
