Abstract The heavy quarks (HQs) are a unique probe of the hot QCD matter properties and their dynamics are coupled to the locally thermalized expanding quark gluon plasma. We present here a novel study of the event by event correlations between light and heavy flavor flow harmonics at LHC energy within a transport approach. Interaction between heavy quarks and light quarks have been taken into account to explore the impact of different temperature dependence for transport coefficients D s and Γ. Our study indicates that v n h e a v y − v n l i g h t correlation and the relative fluctuations of anisotropic flows, σ v n / 〈 v n 〉 , are novel observables to understand the heavy quark-bulk interaction and are sensitive to the temperature dependence even to moderate differences of D s ( T ) , or Γ ( T ) . Hence, the comparison of such new HQ observables to upcoming experimental data at both RHIC and LHC energies can put further constraints on heavy quark transport coefficients and in particular on its temperature dependence toward a solid comparison between phenomenological determination and lattice QCD calculations.

在逐事件传输方法中 LHC 能量处各向异性流的重-轻风味相关性

摘要 重夸克 (HQ) 是热 QCD 物质性质的独特探测器，其动力学与局部热膨胀的夸克胶子等离子体耦合。我们在这里通过传输方法中 LHC 能量处的轻重风味流谐波之间的事件相关性，对事件进行了一项新颖的研究。已考虑重夸克和轻夸克之间的相互作用，以探索不同温度依赖性对输运系数 D s 和 Γ 的影响。我们的研究表明，vnheavy − vnlight 相关性和各向异性流的相对波动 σ vn / 〈 vn 〉 是理解重夸克-体相互作用的新观测值，并且对温度依赖性敏感，甚至对 D s ( T ) 或Γ(T)。因此，
