摘要

我们提出了一种混合方法的扩展，它结合了粘性流体力学、颗粒化、射流能量损失和强子级联，来描述中高p_T区域的数据。这使我们能够结合QGP火球的体积动力学研究重离子碰撞中的微型射流产生和能量损失。将这种混合方法应用于$\sqrt{s_{NN}} = 2.76\，\textrm{TeV}$的LHC Pb-Pb碰撞，证明了强子再散射对中间$p_T$的迷你射流有显著影响。

Effects of hadronic rescattering in mini-jet production and energy loss at the LHC

We present an extension of hybrid approach, which combines viscous hydrodynamics, particlization, jet energy loss and hadronic cascade, to describe data in the intermediate and high $p_T$ regimes. This enables us to study mini-jet production and energy loss in heavy ion collisions, in conjunction with the bulk dynamics of QGP fireball. This hybrid approach is applied for Pb-Pb collisions at the LHC with $\sqrt{s_{NN}} = 2.76\,\textrm{TeV}$, and we demonstrate that hadronic re-scatterings have significant effects on mini-jets with intermediate $p_T$.
