我们利用手征分量夸克模型分析了重轻四夸克束缚态的可能性。这项研究是用变分方法进行的。特别注意了相互作用势的不同项所给出的贡献以及不同颜色通道所起的作用。我们发现两种构型都有一个稳定的状态。分析了这些结构可能出现的衰变模式。
We analyze the possibility of heavy-light tetraquark bound states by means of a chiral constituent-quark model. The study is done in a variational approach. Special attention is paid to the contribution given by the different terms of the interacting potential and also to the role played by the different color channels. We find a stable state for bothandconfigurations. Possible decay modes of these structures are analyzed.
