Analysis of the D-wave $$\Sigma $$ Σ -type charmed baryon states with the QCD sum rules
Abstract We construct the $$\Sigma $$ Σ -type currents to investigate the D-wave charmed baryon states with the QCD sum rules systematically. The predicted masses $$M=3.35^{+0.13}_{-0.18}\,\textrm{GeV}$$ M = 3 . 35 - 0.18 + 0.13 GeV ( $$3.33^{+0.13}_{-0.16}\,\textrm{GeV}$$ 3 . 33 - 0.16 + 0.13 GeV )...
