论文摘要
LHC束的质子内部的夸克和胶子诱导了大型强子对撞机（LHC）通常研究的过程。在这封信中，我们证明，由于质子还包含瘦素，因此也可以靶向LHC上的Lepton诱导的过程。特别是，通过从一个梁和另一个梁的夸克中挑选一张轻子，我们首次对强子对撞机的共鸣单leptoark（LQ）产生进行了全面分析。对于最小的标量LQ，我们得出了由LHC Run II产生的新颖界限，考虑到电子或MUON和UP（$ U $）的所有可能的风味组合（$ d $），一个奇怪的或一个符号夸克。对于具有$ u $或$ d $ quark的风味组合，所获得的限制代表了迄今为止在此类型的LQ上的最严格的约束。还探索了我们未来LHC运行的方法的前景。鉴于拟议的LQ签名的发现范围，我们认为在最终状态下，具有单一轻便顿和单个轻型喷气式喷气式飞机的专用共振搜索应添加到Atlas和CMS协作的Exotics Search Canon中。
Processes commonly studied at the Large Hadron Collider (LHC) are induced by quarks and gluons inside the protons of the LHC beams. In this letter we demonstrate that, since protons also contain leptons, it is possible to target lepton-induced processes at the LHC as well. In particular, by picking a lepton from one beam and a quark from the other beam, we present for the first time a comprehensive analysis of resonant single leptoquark (LQ) production at a hadron collider. In the case of minimal scalar LQs, we derive novel bounds that arise from the LHC Run II considering all possible flavour combinations of an electron or a muon and an up ($u$), a down ($d$), a strange or a charm quark. For the flavour combinations with a $u$ or a $d$ quark, the obtained limits represent the most stringent constraints to date on LQs of this type. The prospects of our method at future LHC runs are also explored. Given the discovery reach of the proposed LQ signature, we argue that dedicated resonance searches in final states featuring a single light lepton and a single light-flavour jet should be added to the exotics search canon of both the ATLAS and the CMS collaboration.
