Newly discovered $\Xi_c^{0}$ resonances and their parameters

Understand

The aim of the present article is investigation of the newly observed resonances $\Xi_c(2923)^{0}$, $\Xi_c(2939)^{0}$, and $\Xi_c(2965)^{0}$ which are real candidates to charm-strange baryons.

• To this end, we calculate the mass and pole residue of the ground-state and excited $1P$ and $2S$ spin-$% 1/2 $ flavor-sextet baryons $\Xi_{c}^{\prime 0}$, $\Xi_{c}^{\prime 0}(1/2^{-})$ and $\Xi_{c}^{\prime 0}(1/2^{+})$ with quark content $csd$, respectively.
• The masses and pole residues of the ground-state and excited spin-$3/2$ baryons $\Xi_{c}^{\star 0}$ are found as well.
• Spectroscopic parameters of these particles are computed in the context of the QCD two-point sum rule method.
