Erratum: Strong decays of exotic and nonexotic heavy baryons in the chiral quark-soliton model [Phys. Rev. D 96, 094021 (2017)]

We present a corrected calculation of the decay widths of the putative exotic heavy ${\mathrm{\Omega }}_c^0$ states to the ground state ${\mathrm{SU}(3)}_{\text{flavor}}$ sextets of heavy baryons. In the article we have used formulas summed over the final spin $1/2$ and $3/2$ sextets. These states, however, are degenerate only in the strict $m_Q\to \infty$ limit, and therefore for phenomenological applications one has to use formulas for fixed final state spin. The correct numerical values of the decay widths are only marginally affected and all conclusions remain unchanged.

Figure 1

Decay widths of the charm baryons. Numbers on the horizontal axis label the decay modes as listed in Table I of the article and Tables 1 and 2. Red full circles correspond to our theoretical predictions. Dark green triangles correspond to the experimental data [1]. Data for decays 4–7 of ${\mathrm{\Sigma }}_c({\mathbf{6}}_1,3/2)$ (down triangles) have been divided by a factor of 5 to fit within the plot area. Widths of two LHCb [2] ${\mathrm{\Omega }}_c$ states that we interpret as pentaquarks are plotted as black full squares with corrected theoretical values shown as red full circles.
