Rapidity-dependent jet energy loss in small systems with finite-size effects and running coupling
摘要：
研究了非对称小碰撞系统中粒子产生和速度相关的射流能量损失的纵向动力学。我们利用一个改进的版本的\textsc{martini}，其中实施了两个改进来计算强耦合QGP液滴对射流能量损失的影响。我们表明，这些现实的处方改善核修改因子计算的结果。我们还观察到可见的能量损失的喷流在热背景下的高多重p-Pb碰撞，和能量损失和椭圆流系数的高能粒子之间的明确的相关性。我们的结论是，系统的测量小系统的中心碰撞中的喷流淬火可以支持的QGP液滴的形成。
英文摘要：
Longitudinal dynamics of particle production and rapidity-dependent jet energy loss are investigated in small and asymmetric colliding systems. We utilize an improved version of \textsc{martini} in which two improvements are implemented to calculate the effect of the strongly coupled QGP droplet on jet energy loss. We show that those realistic prescriptions improve the results of nuclear modification factor calculations. We also observe visible energy loss of jets in a thermal background of high-multiplicity p-Pb collisions, and a clear correlation between the energy loss and elliptic flow coefficients for energetic particles. We conclude that systematic measurements of jet quenching in central collisions of small systems can support the formation of the QGP droplet.
