论文摘要
在本文中，我们处理如何区分LHC/FCC不同\ lqs的签名，如果它们都位于类似的质量和耦合范围内，并且可以目前和未来的山脉。已经发现，硬散射横截面和角度分布可用于区分标量和矢量leptoquarks。另一方面，即使从相同的$ su（2）_l $多重组中，最终状态拓扑和喷气电荷的确定也可以用相同的旋转分离。我们对LHC/FCC的所有主要标准模型（SM）背景进行了基于Pythia8的分析，标量（$ s_1 $）和Vector（$ \ wideTilde {u} _ {1μ}）leptoquarks的质量能量中心为14、27和100 TEV。我们看到，在14 TEV处确认标量leptoquark的证据需要1000 fb $^{ - 1} $的集成光度，而矢量leptoquark可以用很早的数据进行探测。但是，在100 tev的情况下，具有1000 fb $^{ - 1} $的集成光度，质量3.5 TEV的标量leptoquark和质量的向量leptoquark可以轻松探测超过5个TEV。
In this article, we deal with how to distinguish the signatures of different \LQs at the LHC/FCC if all of them lie within similar mass and coupling range and can be produced at present and future colliders. It has been found that hard scattering cross-sections and angular distributions can be used to differentiate scalar and vector Leptoquarks. On the other hand, final state topology and determination of jet charge can separate \LQs with same spin even from same $SU(2)_L$ multiplet. We performed a PYTHIA8 based analysis considering all the dominant Standard Model (SM) backgrounds at the LHC/FCC with centre of mass energies of 14, 27 and 100 TeV for scalar ($S_1$) and vector ($\widetilde{U}_{1μ}$) Leptoquarks. We see that confirming evidence of scalar Leptoquark at 14 TeV requires 1000 fb$^{-1}$ of integrated luminosity, whereas the vector Leptoquark can be probed with very early data. But, at 100 TeV with 1000 fb$^{-1}$ of integrated luminosity, scalar Leptoquark of mass 3.5 TeV and vector Leptoquark of mass more than 5 TeV can be probed easily.
