预言一个新的粲奇重子类似物$D_{s0}^*(2317)$共振

Predicting a new resonance as charmed-strange baryonic analog of $D_{s0}^*(2317)$

摘要:

利用非猝灭夸克模型,我们预言了一个粲奇重子态,即$Ω_{c0}^d(1P,1/2^-)$。它的质量被预测为2945兆电子伏,这是低于$Ξ_c\bar{K}$阈值,由于非平凡的耦合通道效应。因此,$Ω_{c0}^d(1P,1/2^-)$态可以被重新分级为粲奇异介子$D_{s0}^*(2317)$的类似物。这为正在运行的Belle II实验在未来的$Ω_c^{(*)}γ$质谱实验中寻找这种状态提供了一个很好的机会。

英文摘要:

By an unquenched quark model, we predict a charmed-strange baryon state, namely, the $Ω_{c0}^d(1P,1/2^-)$. Its mass is predicted to be 2945 MeV, which is below the $Ξ_c\bar{K}$ threshold due to the nontrivial coupled-channel effect. So the $Ω_{c0}^d(1P,1/2^-)$ state could be regraded as the analog of the charmed-strange meson $D_{s0}^*(2317)$. It is a good opportunity for the running Belle II experiment to search for this state in the $Ω_c^{(*)}γ$ mass spectrum experiment in the future.
