论文摘要
连贯协作的CENNS-10实验最近报道了在液氩中首次检测到相干弹性中微子核散射（CEVNS），其意义超过3σ$。在这项工作中，我们利用新数据来探测各种有趣的参数，这些参数对于标准模型内外的CEVN至关重要。对这些数据的专门统计分析表明，在大多数情况下，当前的限制都会显着改善。我们得出了对氩气中性RMS电荷半径的首次测量，并改善了低能量状态中弱混合角的测定。我们还更新了有关中微子非标准相互作用，电磁特性和光中微子相互作用的约束，相对于从第一个相干CSI数据得出的介导器。
The CENNS-10 experiment of the COHERENT collaboration has recently reported the first detection of coherent-elastic neutrino-nucleus scattering (CEvNS) in liquid Argon with more than $3 σ$ significance. In this work, we exploit the new data in order to probe various interesting parameters which are of key importance to CEvNS within and beyond the Standard Model. A dedicated statistical analysis of these data shows that the current constraints are significantly improved in most cases. We derive a first measurement of the neutron rms charge radius of Argon, and also an improved determination of the weak mixing angle in the low energy regime. We also update the constraints on neutrino non-standard interactions, electromagnetic properties and light mediators with respect to those derived from the first COHERENT-CsI data.
