The SBND is the next generation of the liquid argon time projection chamber experiment and part of the short-baseline neutrino programme at Fermilab. It will start taking data in 2024, and due to the proximity to the source of the neutrino beam, it will detect the highest so far number of neutrino interactions. That will allow for the first precision measurements of the rare processes, e.g. the quasi-elastic Cabbibo suppressed processes with a production of a hyperon (????) instead of the nucleon in the final state. The students will work on selecting the signal events with such processes while removing other types of interactions that could mimic such processes. The SBND is a surface detector, and the analysis will require an algorithm optimisation to reject the cosmic muon background. The student will also support the commissioning and data-taking efforts. They will become a subsystem expert during their LTA at Fermilab and continue when they return to Lancaster.

SBND是下一代液体氩时间投影室实验，也是费米拉布（Fermilab）短基线中微子计划的一部分。它将在2024年开始获取数据，并且由于靠近中微子束的来源，它将检测到迄今为止最高数量的中微子相互作用。这将允许对稀有过程的第一个精度测量，例如准弹性Cabbibo抑制了在最终状态下的超子（???）而不是核子的产生的过程。学生将通过此类过程选择信号事件，同时删除可能模仿此类过程的其他类型的互动。 SBND是一个表面检测器，分析将需要算法优化才能拒绝宇宙哑光背景。该学生还将支持调试和数据投入工作。他们将在Fermilab的LTA期间成为子系统专家，并在返回兰开斯特时继续。
