Description

对马约拉纳中微子的研究是当前粒子物理领域探索超出标准模型新物理的热点研究方向,无中微子双贝塔衰变(NLDBD)是实验上可以确认中微子马约拉纳属性的稀有核衰变。PandaX-III合作组致力于打造具有国际竞争力的百公斤靶质量实验,采用基于气体微结构探测器技术的高压气氙时间投影室来寻找Xe-136的NLDBD过程,其最显著优势在于能够通过带电粒子径迹特征进行信号本底鉴别,进而大幅提高实验对NLDBD的探测灵敏度。本报告将从PandaX-III实验中带电粒子径迹特征分析入手,基于机器学习方法开展信号鉴别、事例顶点重建等粒子特征分析工作,推动PandaX-III朝着零本底实验条件发展。
