摘要：

在重离子碰撞中，急剧下降的喷流谱对喷流观测量的介质修正产生偏差。为了探索这种偏差，我们开发了一种新的分析框架来研究淬火喷流谱及其累积。我们包括许多与能量损失相关的效应，如软和硬介质诱导的发射，加宽，弹性散射，喷流碎裂，圆锥尺寸，相干效应等。我们表明，不同的喷流光谱为基础的可观测量是连接的，例如，核修饰、光谱移位和分位数程序。我们提出了第一个预测的核修饰因子和分位数程序与锥大小的依赖性。作为一个例子，我们比较了双喷注和玻色子+喷注事件，揭示了谱偏置效应。我们改进夸克，胶子喷注分类使用参数的基础上的累积。除了指出它的灵活性，我们将我们的框架与其他能量损失模型，如混合弱，强耦合。

英文摘要：

The steeply falling jet spectrum induces bias on the medium modifications of jet observables in heavy-ion collisions. To explore this bias, we develop a novel analytic framework to study the quenched jet spectrum, and its cumulative. We include many energy-loss-related effects, such as soft and hard medium induced emissions, broadening, elastic scattering, jet fragmentation, cone size, coherence effects, etc. We show that, different jet spectrum-based observables are connected, e.g., the nuclear modification, spectrum shift, and the quantile procedure. We present the first predictions for the nuclear modification factor and the quantile procedure with cone size dependence. As an example, we compare dijet and boson+jet events to unfold the spectrum bias effects. We improve quark-, and gluon-jet classification using arguments based on the cumulative. Besides pointing out its flexibility, we apply our framework with other energy loss models such as the hybrid weak-, strong-coupling.
