标题： Triply heavy tetraquark states in a mass-splitting model

摘要： 在一种改进的色磁相互作用模型中，假设$X(4140)$为最低的$1^{++}$ $cs\bar{c}\bar{s}$ 四夸克态，并将其作为参考态，我们系统地研究了三重重四夸克态$QQ\bar{Q}\bar{q}$($Q=c,b;q=u,d,s$) 的质量。 由于它们的质量较高，没有发现稳定的四夸克态。 使用一种简单的方案，我们还估计了重排衰变通道的部分宽度和相关比值。 如果其观测质量与部分宽度比值与我们的预测相符，一个紧凑的三重重四夸克候选态将更受青睐。 我们希望目前的工作对进一步的研究有所帮助。 显示英文摘要

摘要： In a modified chromomagnetic interaction model, assuming $X(4140)$ to be the lowest $1^{++}$ $cs\bar{c}\bar{s}$ tetraquark and treating it as the reference state, we systematically investigated the masses of the triply-heavy tetraquark states $QQ\bar{Q}\bar{q}$ ($Q=c,b;q=u,d,s$). Because of their higher masses, no stable tetraquarks were found. Using a simple scheme, we also estimated the partial widths of the rearrangement decay channels and relevant ratios. A compact triply heavy tetraquark candidate would be favored if its observed mass and partial width ratios were comparable with our predictions. We hope that the present work will be helpful for further studies.
