论文摘要
尽管具有较高量规组的标准模型的各种扩展预测了链球菌的存在，但在任何围墙中都没有观察到它们。在本文中，我们研究了像Hera，LHEC和FCC-HE这样的几个过去和未来$ E $ -E $ - $ P $ call的前景，以通过辐射幅度零来检测它们。我们发现，在$ e $ -E $ -P $ collider的树级单光子振幅中显示零的Leptoquark在$ e $ e $-umγ$ collider的互补套装中。我们提出了HERA，LHEC和FCC-HE（运行II）的基于毕曲霉的分析，以通过辐射振幅零来检测分别具有70 GEV，900 GEV和1.5 TEV（2.0 TEV）的Leptoquarks。
Though various extensions of the Standard Model with higher gauge group predict the existence of leptoquarks, none of them has been observed yet at any of the colliders. In this paper, we study the prospect of several past and future $e$-$p$ colliders like HERA, LHeC and FCC-he to detect them through radiation amplitude zero. We find that the leptoquarks showing zeros in the tree-level single-photon amplitudes at $e$-$p$ collider lie within the complementary set of those exhibiting zeros at $e$-$γ$ collider. We present a PYTHIA-based analysis for HERA, LHeC and FCC-he (run II) to detect the leptoquarks with masses 70 GeV, 900 GeV and 1.5 TeV (2.0 TeV) respectively through radiation amplitude zero.
