Title: 辐射修正来自隐秘中微子相互作用及其对中微子散射实验的影响

Abstract: New, neutrinophilic mediators are one potential extension beyond the Standard Model of particle physics. Often, studies of neutrinophilic mediator consist of searching for direct evidence of its production and/or its tree-level virtual effect for generating strong neutrino self-interaction. In this work, we focus instead on the fact that such new mediators \textit{also} lead to deviations in neutrino-matter scattering via radiative corrections. With a mediator mass well below the electroweak scale, these effects are potentially observable in a variety of contexts, including coherent elastic neutrino-nucleus scattering (CEvNS), neutrino deeply-inelastic scattering ($\nu$DIS), and neutrino-electron scattering (e.g., at Borexino). Additionally, such effects lead to new contributions to the $Z$-boson decay width and to non-standard neutrino interactions relevant for long-baseline oscillation experiments. We explore all of these scenarios in some depth, building on the rich phenomenology associated with neutrinophilic mediators. Show Chinese abstract

Abstract: 新的、对中微子有亲和力的媒介粒子是粒子物理标准模型之外的一种潜在扩展。 通常，对中微子有亲和力的媒介粒子的研究包括寻找其产生和/或其树级虚效应的直接证据，以生成强烈的中微子自相互作用。 在这项工作中，我们则关注这样的新媒介粒子\textit{也}通过辐射修正导致中微子-物质散射的偏差。 当媒介粒子的质量远低于电弱尺度时，这些效应在多种情况下可能被观测到，包括相干弹性中微子-核子散射（CEvNS）、中微子深度非弹性散射（$\nu$DIS）以及中微子-电子散射（例如，在Borexino实验中）。 此外，这些效应会导致$Z$-玻色子衰变宽度的新贡献，以及对长基线振荡实验相关的非标准中微子相互作用。 我们深入探讨了所有这些情形，并基于与中微子有亲和力的媒介粒子相关的丰富现象学进行研究。
