论文摘要
鉴于Leptoquarks（LQS）在$ b $ - 米森腐烂中的非通道的提示正在享受文艺复兴时期。我们提出了新的大型强子对撞机（LHC）搜索不仅依赖强大生产的这种假设状态，而且还可以从Quark-Lepton歼灭中获得重要的贡献。对于涉及底部夸克和tau Lepton（$ b +τ$）的共振信号的情况，顶级夸克和缺失的横向能量（$ e_ {t}^{\ rm miss miss} $）和light-flavour jets jets jets plus $ e_ {t}^{t}^{t}^{\ rm Miss} $，我们对现实分析的策略进行了详细的策略，并提供了详细的策略，未来LHC的LQ签名运行。我们的分析使我们能够对第三代单元向量vector LQ的质量和耦合产生一系列严格的约束，这表明在LHC Run Run III和高光度LHC中，提出的搜索渠道可以探测$ B $ - $ physics Anomalies的LQ参数空间的有趣部分。鉴于提议的$ b +τ$签名的范围，我们建议将针对此最终状态的专用共鸣搜索添加到Atlas和CMS的Exotics Search Canon中。
Given the hints of lepton-flavour non-universality in $B$-meson decays, leptoquarks (LQs) are enjoying a renaissance. We propose novel Large Hadron Collider (LHC) searches for such hypothetical states that do not rely on strong production only, but can also receive important contributions from quark-lepton annihilation. For the cases of a resonant signal involving a bottom quark and a tau lepton ($b + τ$), a top quark and missing transverse energy ($E_{T}^{\rm miss}$) and light-flavour jets plus $E_{T}^{\rm miss}$, we develop realistic analysis strategies and provide detailed evaluations of the achievable sensitivities for the corresponding LQ signatures at future LHC runs. Our analyses allow us to derive a series of stringent constraints on the masses and couplings of third-generation singlet vector LQs, showing that at LHC Run III and the high-luminosity LHC the proposed search channels can probe interesting parts of the LQ parameter space addressing the $B$-physics anomalies. In view of the reach of the proposed $b + τ$ signature, we recommend that dedicated resonance searches for this final state should be added to the exotics search canon of both ATLAS and CMS.
