用MINOS寻找不育中微子

Searching for Sterile Neutrinos with MINOS

Ashley Timmons

摘要:

本文介绍了利用2005 - 2012年的$10.56 \times 10^{20}$靶上质子数据集进行3+1无菌中微子搜索的最新结果。通过寻找由大质量分裂驱动的振荡,MINOS通过使用带电电流样本的任何能量依赖偏差对无菌中微子的存在敏感,以及查看远和近探测器之间的中性电流事件之间的任何相对赤字。本文将讨论新的分析,使搜索无菌中微子设置在参数空间$\{Δm^{2}_{41}, \sin^2θ_{24}\}$以前未探索的区域的限制。所提出的结果可以与LSND和MiniBooNE建议的参数空间进行比较,并补充了以前在电子中微子外观通道中对无菌中微子的其他实验搜索。

英文摘要:

This document presents the latest results for a 3+1 sterile neutrino search using the $10.56 \times 10^{20}$ protons-on-target data set taken from 2005 - 2012. By searching for oscillations driven by a large mass splitting, MINOS is sensitive to the existence of sterile neutrinos through any energy dependent deviations using a charged current sample, as well as looking at any relative deficit between neutral current events between the far and near detectors. This document will discuss the novel analysis that enabled a search for sterile neutrinos setting a limit in the previously unexplored regions in the parameter space $\{Δm^{2}_{41}, \sin^2θ_{24}\}$. The results presented can be compared to the parameter space suggested by LSND and MiniBooNE and complements other previous experimental searches for sterile neutrinos in the electron neutrino appearance channel.
