论文摘要
我们研究了中等内部动量扩大对核碰撞中产生的喷气对的观测值的影响。通过核碰撞的蒙特卡洛模拟获得这些二甲虫，在该模拟中，碰撞核中的部分是通过未集成的Parton密度来描述的，然后它们随后在夸克 - 胶状等离子体（QGP）的介质中进行了传播。对于QGP中的喷射进化，考虑了横向到传入粒子的动量以及中等感应辐射的动量。在对喷射液压的实验LHC数据进行了有利的比较之后，我们对Dijets的去相关做出了预测。特别是，我们研究了与高斯分布后的横向动量扩展的偏差。
We study the influence of in-medium transverse momentum broadening on observables of jet pairs produced in nuclear collisions. These dijets were obtained numerically via the Monte-Carlo simulations of nuclear collisions, where the partons within the colliding nuclei were described via unintegrated parton densities, and their subsequent propagation within the medium of a quark-gluon plasma (QGP). For jet-evolution in the QGP both, kicks transverse to the momentum of the incoming particle as well as medium induced radiation were considered. After favorable comparison of our results with experimental LHC-data on jet-quenching we make predictions for the decorrelation of dijets. In particular, we study deviations from a transverse momentum broadening that follows a Gaussian distribution.
