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 (\( {E}_T^{\mathrm{miss}} \)) and light-flavour jets plus \( {E}_T^{\mathrm{miss}} \), 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.

鉴于在B介子衰变中存在轻子风味非通用性的迹象，轻石夸克（LQs）正在复兴。我们提出新颖的大型强子对撞机（LHC）搜索这样的假设状态，这些状态不仅仅依赖于强产量，而且还可以从夸克-轻子an灭中获得重要的贡献。对于涉及底部夸克和tau轻子（b + τ），顶部夸克和缺少横向能量（\（{E} _T ^ {\ mathrm {miss}} \））和淡味的共振信号的情况喷气机加\（{E} _T ^ {\ mathrm {miss}} \），我们开发了切合实际的分析策略，并在未来的LHC运行中提供了对相应LQ签名可达到的灵敏度的详细评估。我们的分析使我们能够得出对第三代单重态向量LQ的质量和耦合的一系列严格约束条件，表明在LHC Run III和高亮度LHC时，建议的搜索通道可以探查LQ参数空间寻址的有趣部分。的乙-物理异常。考虑到建议的b + τ签名的范围，我们建议将针对此最终状态的专用共振搜索添加到ATLAS和CMS的奇异搜索规范中。
