论文摘要
我们研究了与tau质量下质量的轻型bino样中性诺相关的现象学，这违反了最小的超对称标准模型。这是一个良好动机的示例，即产生潜在的光线和长寿的外来颗粒，这可能在遥远检测器实验中进行测试，例如大型强子对撞机的FASER实验。通过详细理解光奇异的费物与标准模型物质的相互作用，尤其是望元部门的相互作用，对发现潜力的定量评估或限制的提取。在这里，我们提出了对这种粒子衰变的系统分析，并继续对低能量效应的模型独立推导，以便可以将这种形式主义转移到其他紫外线完成中，甚至可以作为独立的有效现场理论。然后，我们强调了可能的现象学的多样性，并更具体地讨论与违反超对称框架的R-Parity相关的特征，例如中子 - 抗雷剂振荡。
We study the phenomenology associated with a light bino-like neutralino with mass under the tau mass in the context of the R-parity violating Minimal Supersymmetric Standard Model. This is a well-motivated example of scenarios producing potentially light and long-lived exotic particles, which might be testable in far-detector experiments, such as the FASER experiment at the Large Hadron Collider. A quantitative assessment of the discovery potential or the extraction of limits run through a detailed understanding of the interactions of the light exotic fermion with Standard Model matter, in particular, the hadronic sector. Here, we propose a systematic analysis of the decays of such a particle and proceed to a model-independent derivation of the low-energy effects, so that this formalism may be transposed to other UV-completions or even stand as an independent effective field theory. We then stress the diversity of the possible phenomenology and more specifically discuss the features associated with the R-parity violating supersymmetric framework, for example neutron-antineutron oscillations.
