论文摘要
矢量样的夸克（VLQ）是TEV能量量表以外的标准模型以外的物理的潜在特征，并且在Atlas和CMS实验中都提出了重大努力，以寻找这些粒子。为了使这些搜索结果在最合理的VLQ理论的背景下更加相关，以一般方式呈现分析结果是很重要的。我们研究了与单独产生的VLQ搜索的这种解释相关的挑战，并提出了一个广义的半分析框架，该框架允许根据VLQ Lagrangian的无约束，免费参数对结果进行独立的铸造。我们还提出了对校正因子的简单参数化，以便在大衰减宽度下单个VLQ生产横截面。我们说明了如何使用提出的框架来方便地表示统计限制，通过数值重新解释基准图集和CMS分析的结果。
Vector-like Quarks (VLQs) are potential signatures of physics beyond the Standard Model at the TeV energy scale and major efforts have been put forward at both ATLAS and CMS experiments in search of these particles. In order to make these search results more relatable in the context of most plausible theories of VLQs, it is deemed important to present the analysis results in a general fashion. We investigate the challenges associated with such interpretations of singly produced VLQ searches and propose a generalized, semi-analytical framework that allows a model-independent casting of the results in terms of unconstrained, free parameters of the VLQ Lagrangian. We also propose a simple parameterization of the correction factor to the single VLQ production cross-section at large decay widths. We illustrate how the proposed framework can be used to conveniently represent statistical limits by numerically reinterpreting results from benchmark ATLAS and CMS analyses.
