We present a coherent model that combines jet production from perturbative QCD with strongly-coupled jet-medium interactions described in holography. We use this model to study the modification of an ensemble of jets upon propagation through a quark-gluon plasma resembling central heavy ion collisions. Here the modification of the dijet asymmetry depends strongly on the subleading jet width, which can therefore be an important observable for studying jet-medium interactions. We furthermore show that the modification of the shape of the leading jet is relatively insensitive to the dijet asymmetry, whereas the subleading jet shape modification is much larger for more imbalanced dijets. Finally, we compare the results of our holographic model to a recent CMS measurement.

我们提出了一个相干模型，该模型将来自微扰 QCD 的射流产生与全息术中描述的强耦合射流-介质相互作用相结合。我们使用这个模型来研究射流集合在通过类似于中心重离子碰撞的夸克-胶子等离子体传播时的修改。在这里，双射流不对称性的修改在很大程度上取决于次引导射流宽度，因此这可以成为研究射流-介质相互作用的重要观察结果。我们进一步表明，前导射流形状的修改对双射流不对称性相对不敏感，而次导射流形状修改对于更不平衡的双射流要大得多。最后，我们将全息模型的结果与最近的 CMS 测量结果进行比较。
