论文摘要
部分波分析(PWA)是使用Hadronic多体式最终状态腐烂研究共振结构的重要工具。几年来,对此类分析的更独立的方法已用于各种衰减最终状态。但是,到目前为止,这些方法主要应用于部分波的子集,也称为释放波。在本文中,我们探讨了扩展与模型无关的方法的可能性和局限性。我们系统地将各种不同的拟合模型应用于伪数据集的分析,以研究用于释放波的数学描述的影响以及同时释放波浪的选择。我们可以证明存在合适的方法,这些方法仅将限制限制到释放部分波的子集中,并证明了以前的作品中存在的隐藏警告。
Partial-wave analyses (PWA) are an essential tool for studying resonance structures in decays with hadronic multi-body final states. For several years, more model-independent approaches to such analyses have been used for various decay final states. However, up to now, these methods have mostly been applied to sub-sets of partial waves, also called freed waves. In this article, we explore possibilities and limitations of extended model-independent approaches. We systematically apply various different fit models to the analysis of pseudo data sets, to study both the impact of the mathematical description used for the freed waves and the choice of simultaneously freed waves. We can show that suitable methods exist, which lift restrictions to only sub-sets of freed partial waves and demonstrate hidden caveats present in previous works.
