通过逐事件基础上的朗之万动力学与相对论玻尔兹曼输运方法耦合,讨论粲强子横向动量微分径向流\(v_0(p_T)\)。提出其作为探测重夸克与夸克 - 胶子等离子体相互作用强度的可观测量,表明它在中等横向动量对重夸克输运系数敏感,低动量时对强子化也敏感。
AI 中文摘要
我们在逐事件基础上,讨论了在与相对论玻尔兹曼输运方法耦合的朗之万动力学中,粲强子的横向动量微分径向流\(v_0(p_T)\)。我们提出重味\(v_0(p_T)\)作为一种新的可观测量,用于探测重夸克与膨胀的夸克 - 胶子等离子体相互作用的强度。通过比较空间扩散系数\(D_s(T)\)的不同温度依赖性,表明\(v_0(p_T)\)在中等横向动量时对重夸克输运系数保持强烈敏感性。在低横向动量时,该可观测量对强子化也敏感,我们观察到\(\Lambda_c\)重子的\(v_0(p_T)\)比\(D\)介子的大。
英文摘要
We discuss the $p_T$-differential radial flow $v_0(p_T)$ of charmed hadrons within a Langevin dynamics coupled to relativistic Boltzmann transport approach in an event-by-event basis. We propose heavy flavour $v_0(p_T)$ as a novel observable to probe the strength of the interaction of heavy quarks with the expanding Quark-Gluon Plasma. By comparing different temperature dependence for the spatial diffusion coefficient $D_s(T)$ we show that the $v_0(p_T)$ keep a strong sensitivity to the heavy-quark transport coefficients at intermediate $p_T$. At low $p_T$, the observable is also sensitive to hadronization where we observe a larger $v_0(p_T)$ for $Λ_c$ baryons than for $D$ mesons.
