论文摘要
我们对三种不同的型号（即所谓的通用，$ b-l $和$l_μ-l_τ$型号）提出了新的约束，涉及尚未观察到的光线vector $ z'$中介器，通过利用最近在Argon and Cesium-iodiide conterorent coherent coherent conecoration cohorent and Cesium-iodiide contoration the COESIUM-NS的相干弹性弹性中性核中心核酸群（CE $ ns）。我们比较了从上述数据集的组合获得的结果与固定目标，加速器，太阳中微子和反应器CE $ν$ ns实验中的搜索的限制，以及可以解释MUON的异常磁矩的参数区域。我们表明，对于通用和$ b-l $模型，连贯的数据使我们能够在Light Vector Mediator Mass，$ M_ {Z'} $和耦合中施加严格的限制，$ G_ {Z'} $，参数空间。
We present new constraints on three different models, the so-called universal, $B-L$ and $L_μ-L_τ$ models, involving a yet to be observed light vector $Z'$ mediator, by exploiting the recent observation of coherent elastic neutrino-nucleus scattering (CE$ν$NS) in argon and cesium-iodide performed by the COHERENT Collaboration. We compare the results obtained from a combination of the above data sets with the limits derived from searches in fixed target, accelerator, solar neutrino and reactor CE$ν$NS experiments, and with the parameter region that could explain the anomalous magnetic moment of the muon. We show that for the universal and the $B-L$ models, the COHERENT data allow us to put stringent limits in the light vector mediator mass, $M_{Z'}$, and coupling, $g_{Z'}$, parameter space.
