Searching for Low Energy Neutrinos and Beam Exotics with Scintillation

液态Ar时间投影室(LArTPC)由于其优越的位置和能量分辨率，正被广泛用作中微子探测器。英国主要参与了下一代沙丘LArTPC，它将在未来十年建造，以及短基线近探测器，将于2020年获得数据。LArTPC主要使用电离电荷来重建事件，但Ar也是一种熟练的闪烁体。曼彻斯特小组在开发使用闪烁光进行最先进的物理测量方法方面走在了前列，特别是那些仅使用电离电荷很难执行的测量，即需要快速计时或具有低能量沉积。最近提出了一系列模型来预测中微子束中产生的可能是暗物质粒子的可行候选者的重奇异粒子，而SBND处于独特的位置，因为它靠近中微子目标来寻找它们。学生将致力于开发SBND(和沙丘)中的闪烁光重建方法，并使用它们来寻找SBND中的此类粒子。如果时间允许，他还将使用开发的方法在沙丘上搜索超新星中微子。

Liquid argon Time Projection Chambers(LArTPC) are becoming widely used asneutrino detectors thanks to their excellent position and energy resolution.The UK has major involvement in the next generation DUNE LArTPC, which willbe built in the next decade as well as the Short Baseline Near Detector, whichis set to take data in 2020. LArTPCs use mostly ionization charge toreconstruct events, but argon is also a proficient scintillator. The Manchestergroup is at the forefront of developing the methods of using scintillation lightto perform state-of-the art physics measurements, particularly those thatwould be difficult to perform using only ionization charge i.e. requiring fasttiming or having low energy deposits.A wide range of models has been recently proposed that predict heavy exoticparticles produced in neutrino beams that could be viable candidates for darkmatter particles and SBND is in a unique position, given its near position to theneutrino target to search for them. The student will work on developing thescintillation light reconstruction methods in SBND (and DUNE) and use them tosearch for such particles in SBND. If time allows, he will also use the developedmethods to develop a search for supernova neutrinos in DUNE.
