论文摘要
我们研究的主要目的是通过采用有效的QFT模型来了解某些常规和非规定的中间状态的性质。我们从包含独特的$ q \ bar {q} $种子状态的相对论拉格朗日人开始，该状态与原始状态的低质量衰减产品紧密结合。我们发现，某些状态可能会作为较重的$ q \ bar {q} $ mesons的动态生成的伴侣杆。特别是我们表明$ k^*_ 0（700）$是众所周知的$ k^*_ 0（1430）$共振的伴侣，$ x（3872）$以（虚拟的）伴侣的（$χ_{c1}}（c1}}（2p）$的（4008）$ y（4008）$的nore and sonemant，ye Entious norect nore and the Entious，但in Storatioun noratious，ye Entious，但$ψ（4040）$。
The main aim of our study is to understand the nature of some conventional and non-conventional mesonic states by applying effective QFT models. We start from the relativistic Lagrangians containing a unique $q\bar{q}$ seed state which is strongly coupled to the low-masses decay products of the original state. We find out that some states may appear as a dynamically generated companion poles of the heavier $q\bar{q}$ mesons. In particular we show that $K^*_0(700)$ is a companion pole of the well-known $K^*_0(1430)$ resonance, $X(3872)$ emerges as a (virtual) companion pole of $χ_{c1}(2P)$, and the puzzling $Y(4008)$ is not a real state, but a spurious enhancement which appears when studying the state $ψ(4040)$.
