论文摘要
用相对论重离子碰撞产生的夸克gluon等离子体(QGP)中硬质部分的相互作用会导致重建喷头的内部结构的特征修改。观察到的大部分射流子结构修改源于QGP对硬质partons沉积的能量和动量的反应。因此,对理论计算中培养基反应的良好控制对重离子碰撞中的培养基修饰(淬火)喷头的定量理解有用。我们提出了一种改进的方法,可以在喷射淬火模型珠宝中处理中等响应,并为各种喷气台结构可观察到的结果提供了结果。与旧方案相比,新的后坐力处理更具用途和健壮,可以更好地控制许多可观察力,尤其是大大改善了对喷气质量的描述。
Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed jet sub-structure modifications stem from the QGP's response to energy and momentum deposited by hard partons. Good control over medium response in theoretical calculations is thus instrumental to a quantitative understanding of medium modified (quenched) jets in heavy ion collisions. We present an improved way of handling the medium response in the jet quenching model JEWEL and present results for a variety of jet sub-structure observables. The new recoil handling is more versatile and robust than the old scheme, giving a better control over many observables and, in particular, greatly improves the description of the jet mass.
