论文摘要
通过连贯的协作，中微子核子相干散射测量为我们提供了独特的能力，可以测试超出标准模型方案的各种功能。在这项工作中，我们使用相干数据来限制标量leptoquarks（LQS）。 LQ在标准模型（SM）的许多扩展中都出现。通常，假定LQ的质量很高，以避免质子衰减的边界。但是，有一些低尺度的LQ模型禁止通过构造质子衰减。我们考虑了两个具有超荷兰y = 1/6的Electroweak Doublet标量LQ模型，Y = 7/6，并在Yukawa耦合的平面和LQ的质量中提供边界。我们还比较了来自其他各种实验的LQ的界限，并发现连贯的范围涵盖了从MEV到TEV的各种LQ质量，并且在某些区域中，约束与其他质量具有竞争力。
Neutrino-nucleus coherent scattering measurements by the COHERENT collaboration provide us with a unique capability to test various beyond the standard model scenarios. In this work, we constrain scalar leptoquarks (LQs) using the COHERENT data. LQs arise in many extensions of the Standard Model (SM). Generally, the mass of the LQs is assumed to be very high to avoid the bounds from proton decay. However, there are low-scale LQ models which prohibit proton decay by construction. We consider two electroweak doublet scalar LQ models with hypercharge Y=1/6, and Y=7/6 and provide the bounds in the plane of the Yukawa coupling and the mass of LQ. We also compare the bounds on LQs coming from various other experiments and find that the COHERENT one covers a wide range of LQ masses from MeV to TeV and in certain regions the constraints are competitive with the others.
