摘要

在对撞机物理学中，强子射流的性质通常被测量为其实验室坐标系动量的函数。然而，射流破碎必须发生在由所有颜色连接的粒子定义的特定静止框架中。由于这个框架可能不是实验室框架，射流的分裂取决于它的兄弟物体的属性。喷流的这种不可分解性对喷流实验技术产生了影响，如喷流标记、增强玻色子测量和寻找超越标准模型的物理。在本文中，我们将描述这种效应，并通过模拟显示其影响。

Experimental impact of jet fragmentation reference frames at particle colliders

In collider physics, the properties of hadronic jets are often measured as a function of their lab-frame momenta. However, jet fragmentation must occur in a particular rest frame defined by all color-connected particles. Since this frame may not be the lab frame, the fragmentation of a jet depends on the properties of its sibling objects. This non-factorizability of jets has consequences for experimental jet techniques such as jet tagging, boosted boson measurements, and searches for physics Beyond the Standard Model. In this paper, we will describe the effect and show its impact as predicted by simulation.
