摘要:

在本文中,我们扩大了以前提出的概念,能源移动的距离。由此产生的可观的质子-质子对撞机实验中识别罕见的过程提供了一种方法。它表明,不同的过程被分组在一起不同,这可以有助于改善实验分析。在大型强子对撞机的$t\bar{t}Z$生产被用作基准来说明该方法的适用性。此外,我们还研究了如何将这些可观测量作为新特征用于深度神经网络的训练。

英文摘要:

In this paper, we expand on the previously proposed concept of Energy Mover's Distance. The resulting observables are shown to provide a way of identifying rare processes in proton-proton collider experiments. It is shown that different processes are grouped together differently and that this can contribute to the improvement of experimental analyses. The $t\bar{t}Z$ production at the Large Hadron Collider is used as a benchmark to illustrate the applicability of the method. Furthermore, we study the use of these observables as new features which can be used in the training of Deep Neural Networks.
