The Leptoquark Hunter's Guide：Pair Production
The Leptoquark Hunter's Guide: Pair Production
摘要：
轻夸克出现在许多新的物理场景中，可能是LHC的下一个重大发现。本文的目的是指出，一个模型无关的搜索策略，涵盖所有可能的leptoquark是可能的，尚未得到充分利用。为了系统化，我们根据一个细夸克矩阵来组织可能的细夸克末态，矩阵中的条目对应于九种实验上可区分的细夸克衰变：{光喷流，b喷流，top}中的任何一种，{中微子，$e/μ$，$τ$ }中的任何一种。这9种可能性可以通过LHC中的细夸克对产生来探索，这在很大程度上是与模型无关的。我们回顾了实验搜索的9个组成部分的leptoquark矩阵的状态，指出其中3个没有得到充分的覆盖。我们请求实验者在尽可能宽的窄夸克质量范围内，将窄夸克截面的边界作为质量的函数来公布。这样的边界对于可靠地重铸一般的轻子夸克模型是必不可少的。为了证明实用程序的leptoquark矩阵的方法，我们收集和总结搜索与leptoquark对生产相同的最终状态，并使用它们来推导出一套完整的最小的Leptoquark模型，跨越所有可能的味道和规范表示标量和矢量leptoquark的界限。
英文摘要：
Leptoquarks occur in many new physics scenarios and could be the next big discovery at the LHC. The purpose of this paper is to point out that a model-independent search strategy covering all possible leptoquarks is possible and has not yet been fully exploited. To be systematic we organize the possible leptoquark final states according to a leptoquark matrix with entries corresponding to nine experimentally distinguishable leptoquark decays: any of {light-jet, b-jet, top} with any of {neutrino, $e/μ$, $τ$}. The 9 possibilities can be explored in a largely model-independent fashion with pair-production of leptoquarks at the LHC. We review the status of experimental searches for the 9 components of the leptoquark matrix, pointing out which 3 have not been adequately covered. We plead that experimenters publish bounds on leptoquark cross sections as functions of mass for as wide a range of leptoquark masses as possible. Such bounds are essential for reliable recasts to general leptoquark models. To demonstrate the utility of the leptoquark matrix approach we collect and summarize searches with the same final states as leptoquark pair production and use them to derive bounds on a complete set of Minimal Leptoquark models which span all possible flavor and gauge representations for scalar and vector leptoquarks.
