大亚湾核电站非标准反中微子相互作用

Non-standard antineutrino interactions at Daya Bay

Rupert Leitner, Michal Malinsky, Bedrich Roskovec, He Zhang

摘要:

本文研究了在大亚湾中微子实验装置上,在源和探测器中钉扎非标准反中微子相互作用效应的前景。众所周知,如果探测过程中的非标准相互作用与产生过程中的非标准相互作用是同一类型的,则它们的净效应可以被归入轻子混合角θ_13的测量值中的仅仅移动。放宽这一假设,大亚湾的远,近探测器测量的反中微子光谱的比例是扭曲的一个特征的方式,和良好的拟合的基础上的标准振荡假设不再可行。我们表明,在一定的条件下,三年的大亚湾运行可以足以提供一个明确的暗示,非标准中微子物理。

英文摘要:

We study the prospects of pinning down the effects of non-standard antineutrino interactions in the source and in the detector at the Daya Bay neutrino facility. It is well known that if the non-standard interactions in the detection process are of the same type as those in the production, their net effect can be subsumed into a mere shift in the measured value of the leptonic mixing angle theta_13. Relaxing this assumption, the ratio of the antineutrino spectra measured by the Daya Bay far and near detectors is distorted in a characteristic way, and good fits based on the standard oscillation hypothesis are no longer viable. We show that, under certain conditions, three years of Daya Bay running can be sufficient to provide a clear hint of non-standard neutrino physics.
