摘要：

经过简单的归一化处理，我们发现在BSM $Z^\prime$ -玻色子衰变产生的任一轻子的横向动量分布中都出现了焦点。探索FP的属性，我们将能够以一般的方式定义一个新的可观测量，焦点不对称性（$A_{\rm FP}$），它可以用来设置对$Z^\prime$宽度的约束。我们讨论了潜在的和灵敏度的$A_{\rm FP}$作为诊断工具的$Z^\prime$物理，考虑各种$Z^\prime$唯象实现。

英文摘要：

We recognise the appearance of a Focus Point (FP) in the transverse momentum distribution of either leptons originating from a BSM $Z^\prime$-boson decay, after a simple normalisation procedure. Exploring the properties of the FP we will be able to define in a general way a new observable, the Focus Point Asymmetry ($A_{\rm FP}$), which can be used to set constrains on the $Z^\prime$ width. We discuss the potential and the sensitivity of the $A_{\rm FP}$ in as diagnostic tool for $Z^\prime$ physics, considering various $Z^\prime$ phenomenological realisations.
