论文摘要
我们调查了$ dd^*$和$ d \ bar {d}^*$高能碰撞中的动量相关性，以阐明$ t_ {cc} $和$ x（3872）$ exotic hadrons的性质。基于经验数据构建了带有通道耦合的单个范围高斯电势。 $ d^0d^{*+} $，$ d^+d^{*0} $，$ d^0 \ bar {d}^{*0} $的动量相关功能，以及$ d^0 \ bar {d}^{*0} $，以及$ d^+d^{* - * - } $ pairs计算，包括coupled-channel效果。我们讨论了外来状态的性质如何反映在相关结果的行为中。
We investigate $DD^*$ and $D\bar{D}^*$ momentum correlations in high-energy collisions to elucidate the nature of $T_{cc}$ and $X(3872)$ exotic hadrons. Single range Gaussian potentials with the channel couplings to the isospin partners are constructed based on the empirical data. The momentum correlation functions of the $D^0D^{*+}$, $D^+D^{*0}$, $D^0\bar{D}^{*0}$, and $D^+D^{*-}$ pairs are computed with including the coupled-channel effects. We discuss how the nature of the exotic states are reflected in the behaviors of the correlation results.
