A new Monte Carlo model of jet quenching in nuclear collisions, CUJET1.0, is applied to predict the jet flavor dependence of the nuclear modification factor for fragments f=π,D,B,e(-) from quenched jet flavors g,u,c,b in central collisions at RHIC and LHC. The nuclear modification factors for different flavors are predicted to exhibit a novel level crossing pattern over a transverse momentum range 5<p(T)<100 GeV which can test jet-medium dynamics in quark gluon plasmas.
一种新的核碰撞中喷注淬火的蒙特卡罗模型，CUJET1.0，被应用于预测 RHIC 和 LHC 中心碰撞中来自淬火喷注味道 g,u,c,b 的碎片 f=π,D,B,e(-)的核修正因子对于不同味道的喷注的依赖。在 5<p(T)<100 GeV 的横动量范围内，不同味道的核修正因子预计会呈现一种新的交叉模式，这可以测试夸克-胶子等离子体中的喷注-介质动力学。
