用事件解构法寻找物理信号

Finding physics signals with event deconstruction

Davison E. Soper, Michael Spannowsky

摘要:

我们开发了一种基于矩阵元素的重建方法,称为事件解构。该方法使用来自硬矩阵元和部分子簇射的信息来分配最终状态是由信号还是背景过程发起的概率。我们将这种方法应用于全强子末态中的Z'衰变到助推顶夸克的信号过程,并讨论了该方法的改进设想。我们发现,事件解构可以大大提高现有的重建技术。

英文摘要:

We develop a matrix element based reconstruction method called event deconstruction. The method uses information from the hard matrix element and a parton shower to assign probabilities to whether a final state was initiated by a signal or background process. We apply this method in the signal process of a Z' decaying to boosted top quarks in an all hadronic final state and discuss envisioned improvements of the method. We find that event deconstruction can considerably improve on existing reconstruction techniques.
