Non-standard interactions (NSI) of the neutrino sector is studied in the framework of coherent elastic neutrino-nucleus scattering (CE\(\nu\)NS). Differential and total cross sections of the CE\(\nu\)NS process for several nuclei are presented for different scale of incoming neutrino energy. Behavior of form factor in accordance with the criteria of coherency process is also shown as a function of momentum transfer. Several benchmarks were implemented according to the proposed advancement of CE\(\nu\)NS experiments. Using recently analyzed bound, we forecast that the NSI cross section spectrum is larger than the standard model (SM) ones and increased for heavier nuclei. Prediction of the NSI bounds is also given in the parameter space of the new interaction strengths by utilizing the deviation of NSI and SM spectrum ratio. All possibilities of non-universal flavor conserving (FC) and flavor violating (FV) process are considered as neutrino interact with the quark constituent of nucleus.

未来相干弹性中微子-核散射实验中非标准中微子相互作用的研究

在相干弹性中微子-核散射(CE \(\ nu \) NS)的框架下研究了中微子扇区的非标准相互作用(NSI )。针对中微子进入能量的不同尺度,提出了几个核的CE \(\ nu \) NS过程的微分截面和总截面。根据相干过程的标准,形状因数的行为也显示为动量传递的函数。根据CE \(\ nu \)的提议改进,实施了多个基准NS实验。使用最近分析的边界,我们预测NSI的横截面谱比标准模型(SM)的谱大,并且对于较重的原子核会增加。通过利用NSI和SM频谱比的偏差,还可以在新的相互作用强度的参数空间中对NSI范围进行预测。中微子与核的夸克成分相互作用时,非通用风味保留(FC)和违背风味(FV)过程的所有可能性都被认为是可行的。
