论文摘要
重型离子碰撞中高能对象的抑制和修饰为在不同长度尺度上访问夸克 - 胶状等离子体的自由度提供了一个重要的窗口。尽管对重离子碰撞中喷气机的性质的越来越精确和差异测量，但是使用喷气机来对夸克 - 胶状等离子体发表明确且独立的陈述仍然具有挑战性。在这里，我将对这些挑战的某些起源进行个人看法，包括建模的困难和乘坐偏见的偏见，这些挑战陷入了对喷气式修饰测量的直接解释。我将讨论一些模型研究，这些研究有助于消除测量中非直觉效应的来源，最后强调数据驱动的方法是一种有趣的机会，以使用Jets以模型的方式研究Quark-Gluon等离子体。
The suppression and modification of high-energy objects, like jets, in heavy-ion collisions provide an important window to access the degrees of freedom of the quark-gluon plasma on different length scales. Despite increasingly precise and differential measurements of the properties of jets in heavy-ion collisions, however, it has remained challenging to use jets to make unambiguous and model-independent statements about the quark-gluon plasma. Here I will give a personal take on some origins of these challenges, including the difficulty of modelling and biases from jet selection that obfuscate the direct interpretation of jet modification measurements. I will discuss a few model studies that have helped to disentangle the source of non-intuitive effects in measurements, and finally highlight data-driven approaches as an interesting opportunity toward studying the quark-gluon plasma in a model-independent way using jets.
