论文摘要
我们研究Casimir缩放量表的破坏，$ C_F/C_A $，由于喷气式飞机在热培养基中的演变。通过使用Jewel，是针对各种可观察到的中等修改的Monte Carlo事件发生器，我们能够分别研究Quark和Gluon发起的喷气机的开发，这些喷气式喷气式飞机与$ Z-$ Boson背靠背生产。关注$ p_t $分配，我们首先得出结论，颜色充电比是恒定但比Casimir缩放大的$ p_t $ jets大。此外，我们的结果似乎表明，夸克和胶子之间培养基引起的级联反应更相似，从而使整个中等淋浴间脱离了真空期望。最后，我们将结果与另一个蒙特卡洛发生器进行了比较，并观察到相同的尺度违规行为。
We study the breaking of Casimir scaling, $C_F/C_A$, due to the evolution of jets in a hot and extended medium. By using JEWEL, a medium modified Monte Carlo event generator validated for a wide set of observables, we are able to study separately the development of quark and gluon-initiated jets produced back-to-back with a $Z-$boson. Focusing on the $p_T$ distribution, we conclude first that the colour charge ratio is constant but larger than Casimir scaling for high $p_T$ jets. In addition, our results seem to indicate that the medium induced cascade is more similar between quarks and gluons, thus driving the overall medium shower scaling away from the vacuum expectation. Finally, we compare our results to another Monte Carlo generator and observe the same scaling violation.
