Abstract
We analyze data from the CsI, liquid Ar and Ge detectors of the COHERENT
experiment and confirm within $1.5\sigma$ that the measured elastic
neutrino-nucleus scattering cross section is proportional to the square of the
number of neutrons in the nucleus, as expected for coherent scattering in the
standard model. We also show how various degeneracies involving nonstandard
neutrino interaction parameters are broken in a combined analysis of the three
datasets.
我们分析了 COHERENT 实验的 CsI、液态 Ar 和 Ge 探测器的数据,并在 1.5 美元的范围内证实,测得的弹性中微子-原子核散射截面与原子核中中子数目的平方成正比,正如标准模型中相干散射所预期的那样。我们还展示了在对三个数据集的综合分析中,涉及非标准中微子相互作用参数的各种退行性是如何被打破的。
