中性流相干弹性中微子-核散射（CE$\nu$NS）的过程，符合标准模型（SM）的预期，最近已被测量的相干实验在Spinning中子源，橡树岭。根据观测到的信号和我们对相关Cs和I同位素的核计算，更新了对常规和奇异中微子物理的约束。本研究集中在各种SM扩展涉及矢量和张量非标准相互作用（NSI）以及中微子的电磁性质，重点是中微子磁矩和中微子电荷半径。此外，模型解决一个轻不育中微子状态和新的传播场，如矢量$Z^\prime$和标量玻色子的情况下进行检查，相应的排除区域的相干实验。
The process of neutral-current coherent elastic neutrino-nucleus scattering (CE$\nu$NS), consistent with the Standard Model (SM) expectation has been recently measured by the COHERENT experiment at the Spallation Neutron Source, Oak Ridge. On the basis of the observed signal and our nuclear calculations for the relevant Cs and I isotopes, the extracted constraints on both conventional and exotic neutrino physics are updated. The present study concentrates on various SM extensions involving vector and tensor non-standard interactions (NSI) as well as neutrino electromagnetic properties with emphasis on the neutrino magnetic moment and the neutrino charge-radius. Furthermore, models addressing a light sterile neutrino state and scenarios with new propagator fields such as vector $Z^\prime$ and scalar bosons are examined, and the corresponding excluded regions by the COHERENT experiment are presented.
