Most of the data of neutrino oscillation experiments can be consistently described by oscillations between the three active neutrino flavors. However, several experiments have found deviations from the predictions of the three-flavor-scenario that might point to the existence of sterile neutrinos. The SOX project is dedicated to the search for these novel neutrinos, aiming to be the first experiment unambiguously verifying or refuting the existence of sterile neutrinos as cause for these anomalies. Therefore, an intense radioactive antineutrino source will be deployed close to the Borexino detector to perform a short-baseline oscillation experiment. The applicants aim to contribute to this fascinating project: We will perform the calibration for a calorimetric measurement of the source activity and will engage in data analysis by investigating detector backgrounds and systematics. Both aspects will significantly enhance the sensitivity for the sterile neutrino search.

中微子振荡实验的大部分数据可以一致地用三种活跃的中微子之间的振荡来描述。然而，几个实验已经发现，与可能指向稀有中微子存在的三味情景的预测存在偏差。SOX项目致力于寻找这些新的中微子，旨在成为第一个明确证实或驳斥这些反常原因的稀有中微子存在的实验。因此，将在Borexino探测器附近部署一个强辐射反中微子源，以进行短基线振荡实验。申请者的目标是为这个引人入胜的项目做出贡献：我们将对源活动的量热测量进行校准，并将通过调查探测器背景和系统学来进行数据分析。这两个方面都将显著提高寻找无菌中微子的灵敏度。
