深度学习模型旨在抑制中微子实验中的碳-14噪声

研究人员开发了三种深度学习模型,包括一个时空图神经网络和两个基于Transformer的模型,用于识别和抑制液体闪烁体探测器中的碳-14衰变产生的光子击中。这些模型旨在通过区分碳-14信号和实际事件信号(尤其是在时空重叠时)来提高中微子实验的能量分辨率。所提出的模型实现了25%至48%的碳-14召回率,同时将电子-正电子事件的误识别率保持在1%以下。 AI

影响 通过提高信噪比,有潜力提高敏感科学实验的数据质量和分辨率。

    利用时空深度学习抑制大型液体闪烁体探测器中的$^{14}\mathrm{C}$光子击中

    arXiv:2603.27727v2 Announce Type: replace-cross Abstract: Liquid scintillator detectors are widely used in neutrino experiments due to their low energy threshold and high energy resolution. Despite the tiny abundance of $^{14}$C in LS, the photons induced by the $\beta$ decay of …
