论文摘要
高能量处的重离子碰撞可以用作一种有趣的方法来重现和研究夸克 - 胶核血浆（QGP）的介质。我们特别研究了在硬二进制碰撞中产生的喷气机及其与暂定培养基的相互作用。这些喷气机是从凯蒂 - 阿尔格里特姆[1]中从蒙特卡洛模拟中获得的，其中碰撞核子内的parton momenta是通过未集成的帕顿分布函数（uppf）来描述的。我们将这些喷气机演变在培养基中，其中包含横向踢（在动量横向到喷射轴的宽度）以及在[3,4]的作品之后，在MinCas-Algorithm [2]内介质诱导的辐射[2]。我们产生定性的结果，以使二重相关。特别是，我们研究了与高斯分布后的横向动量扩展的偏差。 [1] A.

Heavy ion collisions at high energies can be used as an interesting way to recreate and study the medium of the quark-gluon plasma (QGP). We particularly investigate the jets produced in hard binary collisions and their interactions with a tentative medium. These jets were obtained numerically from the Monte-Carlo simulations of hard collisions using the KATIE-algorithm [1], where parton momenta within the colliding nucleons were describe by means of unintegrated parton distribution functions (uPDF). We evolved these jets within a medium that contains both, transverse kicks (yielding a broadening in momentum transvers to the jet-axis) as well as medium induced radiation within the MINCAS-algorithm [2] following the works of [3,4]. We produce qualitative results for the decorrelation of dijets. In particular, we study deviations from a transverse momentum broadening that follows a Gaussian distribution.
