Searching for Sterile Neutrinos and other Beyond the Standard Model phenomena with SBND

SBND(短基线近探测器)实验是位于美国费米拉实验室助推器中微子光束线沿线的多探测器短基线中微子(SBN)计划的一部分。SBN计划中的每个探测器都利用了液态Ar时间投影室(LArTPC)技术。SBN方案的主要目标是通过搜索稀有中微子和其他超越标准模型的现象，处理以前的短基线实验观察到的一些异常现象。SBND还将非常详细地研究重原子核上中微子相互作用的复杂性质，这对下一代液体Ar中微子探测器将是无价的。该博士项目将侧重于通过测量控制无菌中微子振荡和BSM过程的关键参数来解决短基线异常问题。这将涉及在开发专用软件框架方面发挥主导作用，包括实施机器学习技术。最终，该软件将用于处理和分析大型模拟和真实物理数据集。

The SBND (Short-Baseline Near Detector) experiment is part of the multi-detector Short Baseline Neutrino (SBN) programme located along the Booster Neutrino Beamline at Fermilab, USA. Each detector in the SBN programme utilises the liquid argon time projection chamber (LArTPC) technology. The main goal of the SBN programme is to address a number of anomalies observed by previous short baseline experiments through searches for sterile neutrinos and additional beyond the Standard Model (BSM) phenomena. SBND will also study the intricate nature of neutrino interactions on heavy nuclei in great detail, which will be invaluable to the next generation of liquid argon neutrino detectors. This PhD project will focus on addressing the short baseline anomalies through measurements of key parameters which govern sterile neutrino oscillations and BSM processes. This will involve taking a lead role in developing dedicated software frameworks, including the implementation of machine learning techniques. Ultimately, the software will be used to process and analyse large simulated and real physics datasets.
