The production of the \(X(3872)\) particle in heavy-ion collisions has been contemplated as an alternative probe of its internal structure. To investigate this conjecture, we perform transport calculations of the \(X(3872)\) through the fireball formed in nuclear collisions at the LHC. Within a kinetic-rate equation approach as previously used for charmonia, the formation and dissociation of the \(X(3872)\) is controlled by two transport parameters, i.e., its inelastic reaction rate and thermal-equilibrium limit in the evolving hot QCD medium. While the equilibrium limit is controlled by the charm production cross section in primordial nucleon-nucleon collisions (together with the spectra of charm states in the medium), the structure information is encoded in the reaction rate. We study how different scenarios for the rate affect the centrality dependence and transverse-momentum (\(p_T\)) spectra of the \(X(3872)\). Larger reaction rates associated with the loosely bound molecule structure imply that it is formed later in the fireball evolution than the tetraquark and thus its final yields are generally smaller by around a factor of two, which is qualitatively different from most coalescence model calculations to date. The \(p_T\) spectra provide further information as the later decoupling time within the molecular scenario leads to harder spectra caused by the blue-shift from the expanding fireball.

生产的\（X（3872）\） 粒子在重离子碰撞已经被考虑作为它的内部结构的替代探针。为了调查这个猜想，我们 通过在大型强子对撞机的核碰撞中形成的火球对\（X（3872）\）进行了运输计算。在以前用于色拉的动力学速率方程方法中，\（X（3872）\）的形成和解离 受两个传输参数控制，即，它在不断发展的热QCD介质中的非弹性反应速率和热平衡极限。平衡极限是由原始核子-核子碰撞中的魅力产生截面控制的（连同介质中的魅力状态的光谱一起），结构信息被编码为反应速率。我们研究了速率的不同方案如何影响\（X（3872）\）的中心性依赖性和横向动量（\（p_T \））光谱。与松散结合的分子结构相关的更大的反应速率意味着它在火球进化中的形成要比四夸克的形成晚，因此其最终收率通常小两倍左右，这在质量上与迄今为止的大多数聚结模型计算不同。这\（p_T \） 光谱提供了进一步的信息，因为分子场景中较晚的解耦时间会导致由不断扩展的火球的蓝移引起的更硬的光谱。
