Some errors have been detected when studying P-wave bottom baryons of the SUð3Þ flavor 6 F with the spin-parity quantum number J P ¼ 5=2 −. We present the correct results below. To do this, we need the full expression of the J ¼ 5=2 propagator [1]: Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.

“…For the mass spectrum of the Ξ 0 c baryon, there exist many calculations with various models and effective theories in the literature [15][16][17][18][19][20][21][22][23][24][25]. We collect the predicted masses in Table I.…”

“…Besides mass spectra, the radiative and strong decay properties are crucial in pining down the inner structures of a state. Before the LHCb's measurement [12], there are also some discussions of the radiative and strong decay properties of the 1P wave Ξ c states [21,25,[28][29][30][31][32][33][34][35][36].…”

Understanding the newly observed Ξc0 states through their decays

Inspired by the newly observed Ξ 0 c states by the LHCb Collaboration, we investigate the OKubo-Zweig-Iizuka-allowed two-body strong decays of the λ-mode 1P wave Ξ 0 c states within the chiral quark model. Our results indicate that: (i) The newly observed states Ξ c ð2923Þ 0 and Ξ c ð2939Þ 0 are good candidates of the λmode 1P wave Ξ 0 c states with the spin-parity J P ¼ 3=2 − , namely j 4 P λ 3=2 − i and j 2 P λ 3=2 − i, respectively. (ii) The other newly observed state Ξ c ð2965Þ 0 mostly corresponds to the λ-mode 1P-wave Ξ 0 c state with the spin-parity J P ¼ 5=2 − , namely j 4 P λ 5=2 − i. (iii) For the two λ-mode J P ¼ 1=2 − mixed states, the jP λ 1=2 − i 1 is a narrow state with a width of Γ ∼ 15 MeV and mainly decays into Ξ 0 c π, while the jP λ 1=2 − i 2 state has a width of Γ ∼ 52 MeV and dominantly decays into Ξ c π and Λ c K channels. If the broad structure around 2880 MeVobserved at LHCb arises from the new Ξ 0 c state, this state is very likely to be the jP λ 1=2 − i 2 state.

“…Refs. [72,73] applied the light cone QCD sum rules to study its decays to ground-state bottom baryons and a meson considering the heavy quark effective theory. The consistency of the quantum numbers of the Ξ b (6227) − with a P -wave state with J P = 1 2 − , 3 2 − and 5 2 − was also indicated by mass calculation in the quark-diquark picture [74,75].…”

The LHCb Collaboration recently reported the observation of a new excited bottom baryon Ξb(6227)0 and announced an improvement in the measurements related to the previously observed Ξb(6227)− state. We conduct an analysis for Ξb(6227)0 state considering it as isospin partner of the Ξb(6227)− resonance and possibly 1P or 2S excited state with spin J = $$ \frac{3}{2} $$ 3 2 . The corresponding masses for both possibilities have consistent results with the experimental data, indicating that only with the mass sum rules, one can not make exact decision on the nature and quantum numbers of this state. To go further, the decays of these possible excited states to $$ {\Xi}_b^{-}{\pi}^{+} $$ Ξ b − π + final state are also considered and the relevant strong coupling constants are extracted from the light cone sum rules. The obtained decay width values support the possibility of Ξb(6227)0 to be the 1P excited state of Ξb(5945)0 baryon.
