用淋浴解构法寻找物理信号

Finding physics signals with shower deconstruction

Davison E. Soper, Michael Spannowsky

摘要:

介绍了一种在强子环境中寻找新物理的方法--簇射解构。该方法的目标是使用小射流的全信息方法。它为每个事件分配一个数字chi,该数字是信号过程产生该事件的概率与背景过程产生该事件的概率之比的估计值。我们推导出的计算这些概率的解析函数模拟了Pythia或Herwig等全事件发生器的工作,并且可以用图解的方式来描述。作为一个例子,我们将这种方法应用于与Z-玻色子产生的助推希格斯玻色子,并表明这种方法可以是有用的,以区分这个信号的Z+喷流背景。

英文摘要:

We introduce shower deconstruction, a method to look for new physics in a hadronic environment. The method aims to be a full information approach using small jets. It assigns to each event a number chi that is an estimate of the ratio of the probability for a signal process to produce that event to the probability for a background process to produce that event. The analytic functions we derive to calculate these probabilities mimic what full event generators like Pythia or Herwig do and can be depicted in a diagrammatic way. As an example, we apply this method to a boosted Higgs boson produced in association with a Z-boson and show that this method can be useful to discriminate this signal from the Z+jets background.
