摘要:

我们研究了从实现重夸克对称性的耦合通道幺正方法动态产生的粲重子共振。一些状态已经可以用实验观测来识别,例如$Λ_c(2595)$、$Λ_c(2660)$、$Σ_c(2902)$或$Λ_c(2941)$,而另一些状态需要更多实验数据的汇编以及模型的扩展以包括更高阶的贡献。我们还比较了我们的模型与以前的SU(4)方案。

英文摘要:

We study charmed baryon resonances that are generated dynamically from a coupled-channel unitary approach that implements heavy-quark symmetry. Some states can already be identified with experimental observations, such as $Λ_c(2595)$, $Λ_c(2660)$, $Σ_c(2902)$ or $Λ_c(2941)$, while others need a compilation of more experimental data as well as an extension of the model to include higher order contributions. We also compare our model to previous SU(4) schemes.
