RUI: Search for Exotic Particles at the MiniBooNE Experiment

本提案要求巴克内尔大学的一个小组在费米实验室的MiniBooNE实验的基础上开展实验基本粒子物理学的研究和教育项目。该实验包括对KARMEN时间异常的研究，以及寻找中性重轻子、惰性中微子、中性超对称粒子和类轴子粒子。KARMEN异常是在卢瑟福阿普尔顿实验室ISIS散裂中子设施的KARMEN实验中检测到的过量中微子事件，可能是由于罕见的非标准模型p+衰变模式：m+Q0，其中Q0表示大质量，中性，弱相互作用的不稳定粒子。对异常的研究需要对可能的背景贡献进行全面的调查，这是巴克内尔小组提出的工作的主要组成部分。这项工作将与一组本科生合作完成。

This proposal requests support for a group at Bucknell University for a program of research and education in experimental elementary particle physics based on the MiniBooNE experiment at Fermilab. The experiment involves an investigation of the KARMEN timing anomaly and a search for neutral heavy leptons, sterile neutrinos and neutral supersymmetric and axion-like particles. The KARMEN anomaly is an excess of neutrino events detected in the KARMEN experiment at the ISIS spallation neutron facility at Rutherford Appleton Laboratory and may be due to a rare non-Standard Model p+ decay mode: m+Q0 where Q0 denotes a massive, neutral, weakly interacting unstable particle. The study of the anomaly requires a comprehensive investigation of possible background contributions, the main component of the proposed work of the Bucknell group. The work will be performed in collaboration with a group of undergraduates.
