AI总结:

本文研究了广义中微子相互作用的两种常见参数化方法及其关联,比较了CEvNS和深度非弹性散射的约束,并展示了COHERENT实验在低能下的标量相互作用约束优于高能下的张量相互作用约束。

摘要:

广义中微子相互作用(GNI)正逐渐成为描述有效标量、向量和张量相互作用的便利框架。此类相互作用自然地出现在扩展标准模型中,旨在解释中微子性质及其质量起源。本文仔细研究了GNI的两种更常见的参数化方法及其关联,这使得可以在相同基础上比较CEvNS和深度非弹性散射所获得的约束。此外,我们还介绍了从CEvNS测量中获得的当前约束,由COHERENT实验提供,并将其与深度非弹性散射的结果进行比较。我们的结果集中在中微子-夸克相互作用上,并展示了在不同尺度上工作的实验之间的互补性,表明标量相互作用由低能实验如COHERENT更好地约束,而张量相互作用则由深度非弹性散射稳健地约束。

英文摘要:

Generalized neutrino interactions (GNI) are emerging as a convenient framework for describing effective scalar, vector, and tensor interactions. Such interactions arise naturally from extensions of the Standard Model that aim to explain neutrino properties and their mass origin. In this paper, we carefully study the two more common parametrizations for GNI and how to relate them. This allows us to compare bounds obtained from CEvNS and deep-inelastic scattering under the same footing. In addition, we present the current bounds from CEvNS measurements by COHERENT and compare them to those obtained from deep inelastic scattering on the same level. Our results focus on neutrino-quark interactions, and illustrate the complementarity between experiments working at different scales for GNI, showing that scalar interactions are better constrained by low-energy experiments like COHERENT, while tensor interactions are robustly constrained from deep inelastic scattering.
