在LHC上产生新的轻夸克对

Novel Leptoquark Pair Production at LHC

Ilja Doršner, Svjetlana Fajfer, Ajla Lejlić

摘要:

我们介绍了一种新的机制,在大型强子对撞机上的leptoquark对的生产是一个$t$通道拓扑结构和夸克-夸克启动。这种机制在相当一般的条件下运作。其中之一是这两个轻夸克耦合到同一轻子,另一个是这两个轻夸克的费米子数相差2。所提出的机制的强度提供了一种替代的方法,以有效地约束参数空间的两个leptoquark场景在大型强子对撞机,只要满足上述条件。因此,我们提出了一个案例研究,概述了这种新的生产机制的物理潜力。

英文摘要:

We introduce a novel mechanism for the leptoquark pair production at LHC that is of a $t$-channel topology and is quark-quark initiated. This mechanism operates under fairly general conditions. One of them is that the two leptoquarks in question couple to the same lepton and the other one is that the fermion numbers of these two leptoquarks differ by two. The strength of the proposed mechanism provides an alternative way to the conventional processes to efficiently constrain the parameter space of the two leptoquark scenarios at LHC whenever the aforementioned conditions are met. We accordingly present one case study to outline the physics potential of this novel production mechanism.
