Analysis of the D-wave $\Sigma$-type charmed baryon states with the QCD sum rules

We construct the $\Sigma$-type currents to investigate the D-wave charmed baryon states with the QCD sum rules systematically. The predicted masses $M=3.35^{+0.13}_{-0.18}\,\rm{GeV}$ ($3.33^{+0.13}_{-0.16}\,\rm{GeV}$), $3.34^{+0.14}_{-0.18}\,\rm{GeV}$ ($3.35^{+0.13}_{-0.16}\,\rm{GeV}$) and $3.35^{+0.12}_{-0.13}\,\rm{GeV}$ ($3.35^{+0.12}_{-0.14}\,\rm{GeV}$) for the $\Omega_c(0,2,{\frac{1}{2}}^+)$, $\Omega_c(0,2,{\frac{3}{2}}^+)$ and $\Omega_c(0,2,{\frac{5}{2}}^+)$ states are in excellent agreement with the experimental data $3327.1\pm1.2 \mbox{ MeV}$ from the LHCb collaboration, and support assigning the $\Omega_c(3327)$ to be the $\Sigma$-type D-wave $\Omega_c$ state with the spin-parity $J^P={\frac{1}{2}}^+$, ${\frac{3}{2}}^+$ or ${\frac{5}{2}}^+$.
