论文摘要
我们认为，在QCD中，在有限范围内强烈相互作用的流体中传播的单射流。相互作用导致流体中能量摩托车来源的出现。分析了逃脱容器的残留射流以及射流激发的介质的一部分。我们研究了静态与半现实的扩展培养基的效果，它们的喷气机向内行驶与向外行驶。我们根据弱耦合的描述及其与基于强耦合描述的流体动力学介质响应的组合来考虑通过后圈的介质响应，然后将其与流体动力学培养基响应相结合，然后将其掺入射流中。研究了这些限制对射流重建能量，动量和质量的影响，这是远离原始Parton方向的角度的函数。证明培养基中的不同流速构型在喷气式可观察物中产生很大的差异。这项工作强调了软培养基准确的动态建模作为计算喷气修饰的基础的重要性，并对没有这种建模的结果提出了怀疑。
We consider the case, in QCD, of a single jet propagating within a strongly interacting fluid, of finite extent. Interactions lead to the appearance of a source of energy-momentum within the fluid. The remnant jet that escapes the container is analyzed along with portions of the medium excited by the jet. We study the effect of a static versus a semi-realistic expanding medium, with jets traveling inward versus outward. We consider the medium response via recoils in partonic scatterings based on a weakly-coupled description and its combination with hydrodynamical medium response based on a strongly-coupled description, followed by incorporation into a jet. The effects of these limits on the reconstructed energy, momentum and mass of the jet, as a function of the angle away from the original parton direction are studied. It is demonstrated that different flow velocity configurations in the medium produce considerable differences in jet observables. This work highlights the importance of accurate dynamical modeling of the soft medium as a foundation on which to calculate jet modification, and casts skepticism on results obtained without such modeling.
