We present a theoretical study of the medium modifications of the $p_{\rm T}$ balance ($x_{\rm J}$) of dijets in Xe+Xe collisions at $\sqrt{s_{\rm NN}}=5.44$ TeV. The initial production of dijets was carried out using the POWHEG+PYTHIA8 prescription, which matches the next-to-leading-order (NLO) QCD matrix elements with the parton shower (PS) effect. The SHELL model described the in-medium...
We present the first theoretical investigation of Fox-Wolfram moments (FWMs) for multi-jet production in relativistic heavy ion collisions. In this work, jet productions in p+p collisions are computed with a Monte Carlo event generator SHERPA, while the Linear Boltzmann Transport model is utilized to simulate the multiple scattering of energetic partons in the hot and dense QCD matter. The...
二维（2D）喷注层析技术是研究高能重离子碰撞中，喷注介质修正效应的一种工具。它结合了梯度（在本文中表现为横向）和纵向的喷注层析，用于选择横平面内不同初始喷注产生位置的喷注事件。它利用了夸克-胶子等离子体（QGP）的横向梯度和喷注路径长度的横向不对称性和能量损失的特性。在本研究中，我们采用二维喷注层析技术，结合描述喷注部分子在QGP介质中传播的线性玻尔兹曼输运（LBT）模型，研究了光子标记喷注的喷注形状受到的介质修正效应。我们的结果表明，横向不对称度（$A_N^y$）较小或 光子-喷注横动量不平衡性（$x_{J\gamma}=p_T^{\rm...
