对标量轻夸克的对产生进行了限制，考虑了轻夸克衰变为第三代夸克（$t$，$b$）和轻子（$τ$，$ν$）的所有可能.对于上型（$\mathrm{LQ}_{3}^{u}$ $\rightarrow t ν/ b τ$）和下型（$\mathrm{LQ}_{3}^{d}$ $\rightarrow b ν/ t τ$）细夸克，极限是细夸克质量和带电轻子分支比的函数。许多结果是对以前发表的ATLAS检索的重新解释。在所有情况下，使用ATLAS探测器在2015年和2016年记录的质量中心能量为$\sqrt{s}$ = 13 TeV的LHC质子-质子碰撞数据，对应于36.1 fb $^{-1}$的积分光度。对于$\mathrm{LQ}_{3}^{u}$和$\mathrm{LQ}_{3}^{d}$两者，与分支比无关地排除低于800 GeV的质量，对于分支比等于零或1的极限情况，排除低于约1 TeV的质量。
英文摘要：
Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark ($t$, $b$) and a lepton ($τ$, $ν$) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the branching ratio into charged leptons for up-type ($\mathrm{LQ}_{3}^{u}$ $\rightarrow t ν/ b τ$) and down-type ($\mathrm{LQ}_{3}^{d}$ $\rightarrow b ν/ t τ$) leptoquarks. Many results are reinterpretations of previously published ATLAS searches. In all cases, LHC proton-proton collision data at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV recorded by the ATLAS detector in 2015 and 2016 are used, corresponding to an integrated luminosity of 36.1 fb$^{-1}$. Masses below 800 GeV are excluded for both $\mathrm{LQ}_{3}^{u}$ and $\mathrm{LQ}_{3}^{d}$ independently of the branching ratio, with masses below about 1 TeV being excluded for the limiting cases of branching ratios equal to zero or unity.
Search for 1st-Generation Leptoquarks Using the ATLAS Detector
本文报道了在LHC记录的7 TeV ATLAS数据的1/fb中寻找标量细夸克对产生的结果。轻夸克是一种假设的三重色玻色子，它同时带有夸克和轻子的味道，因此衰变为夸克和轻子，与任何标准模型粒子不同。轻夸克产生于许多超越标准模型的理论。在这个分析中检查的通道需要至少一个轻夸克衰变到电子，其中包括最终状态eejj和evjj。没有多余的事件被观察到，从而限制允许leptoquark质量被确定。我们在95%的置信水平上排除了质量m < 660（607）GeV的第一代标量细夸克的产生，假设细夸克衰变到电子的分支分数为1.0（0.5）。
