论文摘要
我们研究了大型强子对撞机的不对称leptoark对生产机制,以提倡其潜在的相关性,以建立对leptoquark参数空间的可靠约束及其有助于正确识别这些有吸引力的新物理学来源的能力。不对称对生产的主要特征将其与通常的Leptoquark对生产区分开来,这是通过以下事实,即通过$ T $ CHANNEL LEPTON在Proton-Proton碰撞中产生的两个Leptoquark并不是彼此之间的共轭。因此,针对此类过程的不对称leptoark对生产的建议名称。我们阐明了先决条件,使得不对称的Leptokark配对生产机制是运行的,并列举了可能产生它的Leptoquark多重组合的所有可能组合。最终,我们在标准模型的几个简单标量leptoark扩展中重新解释了现有的Leptoquark对生产搜索结果,假设Leptoquarks专门夫妇夫妇到电子或MUONS和第一代夸克,以证明适当地包含非对称对生产。因此,我们提供了$ s_1 $,$ s_3 $,$ r_2 $,$ s_1 $+$ s_3 $的准确参数空间约束,以及$ s_1 $+$+$ r_2 $ leptoquark centarios。
We investigate asymmetric leptoquark pair production mechanism at the Large Hadron Collider to advocate its potential relevance to establish reliable constraints on the leptoquark parameter space and its ability to aid in correct identification of these attractive sources of new physics. The main feature of asymmetric pair production that genuinely distinguishes it from the usual leptoquark pair production is given by the fact that the two leptoquarks that are produced in proton-proton collisions through a $t$-channel lepton exchange are not charge conjugates of each other. Hence the proposed name of asymmetric leptoquark pair production for this type of process. We spell out prerequisite conditions for the asymmetric leptoquark pair production mechanism to be operational and enumerate all possible combinations of leptoquark multiplets that can potentially generate it. We finally reinterpret existing leptoquark pair production search results within several simple scalar leptoquark extensions of the Standard Model, assuming that the leptoquarks exclusively couple to either electrons or muons and the first generation quarks, to demonstrate proper inclusion of asymmetric pair production. We consequently present accurate parameter space constraints for the $S_1$, $S_3$, $R_2$, $S_1$+$S_3$, and $S_1$+$R_2$ leptoquark scenarios.
