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. Widths of the excited baryons are evaluated through their decays to final states \(\Lambda _{c}^{+}K^{-}\) and \( \Xi _{c}^{\prime 0}\pi \). These processes are explored by means of the full QCD light-cone sum rule method necessary to determine strong couplings at relevant vertices. Obtained predictions for the masses and widths of the four excited baryons, as well as previous results for 1P and 2S flavor-antitriplet spin-1/2 particles \(\Xi _c^{0}\) are confronted with available experimental data on \(\Xi _{c}^{0}\) resonances to fix their quantum numbers. Our comparison demonstrates that the resonances \(\Xi _c(2923)^{0}\) and \(\Xi _c(2939)^{0}\) can be considered as 1P excitations of the spin-1/2 flavor-sextet and spin-3/2 baryons, respectively. The resonance \(\Xi _{c}(2965)^{0}\) may be interpreted as the excited 2S state of either spin-1/2 flavor-sextet or antitriplet baryon.

本文的目的是研究新观察到的共振\(\Xi _c(2923)^{0}\)、\(\Xi _c(2939)^{0}\)和\(\Xi _c( 2965)^{0}\)是魅力奇异重子的真正候选者。为此，我们计算了基态和激发态的 1 P和 2 S自旋 1/2 味六重子重子的质量和极点残差\(\Xi _{c}^{\prime 0}\) , \ (\Xi _{c}^{\prime 0}(1/2^{-})\)和\(\Xi _{c}^{\prime 0}(1/2^{+})\)分别与夸克含量csd。基态和激发自旋 3/2 重子的质量和极点残基\(\Xi _{c}^{\star 0}\)也被发现。这些粒子的光谱参数是在 QCD 两点求和规则方法的背景下计算的。激发重子的宽度通过它们衰变到最终状态\(\Lambda _{c}^{+}K^{-}\)和\( \Xi _{c}^{\prime 0}\pi \ )。通过确定相关顶点处的强耦合所需的完整 QCD 光锥总和规则方法来探索这些过程。获得的四个激发重子的质量和宽度的预测，以及 1 P和 2 S风味-反三重态自旋 1/2 粒子的先前结果\(\Xi _c^{0}\)面临可用的实验数据在\(\Xi _{c}^{0}\)共振来固定它们的量子数。我们的比较表明共振\(\Xi _c(2923)^{0}\)和\(\Xi _c(2939)^{0}\)可以被认为是自旋 1/2 风味的1 P激发-sextet 和自旋 3/2 重子，分别。共振\(\Xi _{c}(2965)^{0}\)可以解释为自旋 1/2 风味六重子或反三重子的激发 2 S状态。
