上下模单件生产的非共振图

Non-resonant Diagrams for Single Production of Top and Bottom Partners

Avik Roy, Timothy Andeen

摘要:

在ATLAS和CMS实验中,寻找顶部和底部合作伙伴是分析的主要焦点。当单独产生时,这些标准模型第三代夸克的类矢量伙伴保留了相当大的横截面,使它们在各自的拓扑结构中成为有吸引力的搜索候选者。虽然大多数的努力都集中在共振模式的单一生产这些假设的粒子,最主要的模式在狭窄的宽度,最近的研究揭示了广泛和丰富的现象,涉及非共振图。在这封信中,我们分类调查的影响,非共振图上不同的顶部和底部的合作伙伴单一的生产拓扑结构和它们的影响,包括横截面估计。我们还提出了一个参数化计算的校正因子的单矢量夸克产生截面时,这种图包括。

英文摘要:

The search for Top and Bottom Partners is a major focus of analyses at both the ATLAS and CMS experiments. When singly produced, these vector-like partners of the Standard Model third generation quarks retain a sizeable cross-section that makes them attractive search candidates in their respective topologies. While most efforts have concentrated on the resonant mode for single production of these hypothetical particles, the most dominant mode at narrow widths, recent studies have revealed a wide and rich phenomenology involving the non-resonant diagrams. In this letter we categorically investigate the impact of the non-resonant diagrams on different Top and Bottom partner single production topologies and their impact on the inclusive cross-section estimation. We also propose a parameterization for calculating the the correction factor to the single vector-like quark production cross-section when such diagrams are included.
