标题： EFT analysis of New Physics at COHERENT with Dirac neutrinos

摘要： 我们研究了类似于COHERENT的实验对非标准贡献的敏感性，这些贡献属于所谓的$\nu$WEFT框架。后者是最一般的低能有效场论，不仅包括轻SM场还包括额外的右手中微子。我们的分析首次包含了中微子产生（$\pi$介子和$\mu$介子衰变）和中微子探测（通过相干弹性中微子-核散射）中的普遍的新物理效应。尽管具有广泛性，结果可以简洁地表达，并且易于在现有或未来使用有效核电荷的分析中实现。我们利用当前COHERENT数据来限制相应的有效算符，并估计未来测量的灵敏度。 显示英文摘要

摘要： We study the sensitivity of COHERENT-like experiments to non-standard contributions within the so-called $\nu$WEFT framework. The latter is the most general low-energy effective field theory that includes not only the light SM fields but also additional right-handed Dirac neutrinos. Our analysis includes for the first time flavor-general New Physics effects in neutrino production (pion and muon decays) and neutrino detection (through Coherent Elastic Neutrino-Nucleus Scattering). Despite the generality, the results can be written in compact form and are easy to implement in existing or future analyses using effective nuclear charges. We use current COHERENT data to set constraints on the corresponding effective operators, and we estimate the sensitivity of future measurements.
