We present a detailed study of the lowest-lying and resonances both in the heavy quark (bottom and charm) and the strange sectors. We have paid special attention to the interplay between the constituent quark-model and chiral baryon–meson degrees of freedom, which are coupled using a unitarized scheme consistent with leading-order heavy quark symmetries. We show that the [], [] and the [], and the [] admitting larger breaking corrections, are heavy-quark spin-flavor siblings. They can be seen as dressed quark-model states with molecular components of the order of 30%. The has, however, a higher molecular probability of at least 50%, and even values greater than 70% can be easily accommodated. This is because it is located almost on top of the threshold of the pair, which largely influences its properties. Although the light degrees of freedom in this resonance would be coupled to spin-parity as in the , and , the should not be considered as a heavy-quark spin-flavor partner of the former ones. We also show that the chiral two-pole pattern does not have analogs in the charmed and bottomed sectors, because the and channels do not play for heavy quarks the decisive role that the does in the strange sector, and the notable influence of the bare quark-model states for the charm and bottom resonances. Finally, we predict the existence of two and two heavy-quark spin and flavor sibling odd parity states.

最低位[公式省略]和[公式省略][公式省略]共振：从奇怪到底部扇区


我们对重夸克（底夸克和粲夸克）和奇怪扇区的最低层和共振进行了详细研究。我们特别关注组成夸克模型和手征重子介子自由度之间的相互作用，它们使用与前导重夸克对称性一致的酉化方案进行耦合。我们表明，[]、[] 和 []，以及承认较大破缺修正的 []，是重夸克自旋风味的兄弟姐妹。它们可以被视为分子成分约为 30% 的修饰夸克模型态。然而，它具有至少 50% 的较高分子概率，甚至可以轻松适应大于 70% 的值。这是因为它几乎位于该对的阈值之上，这在很大程度上影响了它的属性。尽管该共振中的轻自由度将与自旋宇称耦合，如 、 和 ，但 不应被视为前一夸克的重夸克自旋味伴侣。我们还表明，手性二极模式在粲扇区和有底扇区中没有类似物，因为 和 通道对于重夸克不像奇扇区那样起决定性作用，并且裸夸克的显着影响-魅力和底部共振的模型状态。最后，我们预测存在两个和两个重夸克自旋和风味兄弟奇宇称态。
