SNO+ is a multi-purpose experiment whose main goal is to study the nature of the neutrino mass through the observation of neutrinoless double-beta decay. Detection of this rare process would indicate that neutrinos are elementary Majorana particles, proving that lepton number is not conserved. The SNO+ detector will operate in three distinct phases with different target materials: water, pure liquid scintillator and tellurium-loaded liquid scintillator. During the water phase, the external backgrounds were confirmed to be within expectation, new limits on specific channels of invisible nucleon decay modes were set and the Boron-8 solar neutrino flux was measured and confirmed to be compatible with previous measurements. With a completed water phase, SNO+ is moving towards its main Tellurium-loaded phase. Here, we report the status of the experiment, the recent results and the potential of SNO+ for neutrinoless double-beta decay search.

SNO+ 现状与前景

SNO+ 是一项多用途实验，其主要目标是通过观察无中微子的双β衰变来研究中微子质量的性质。检测到这个罕见的过程将表明中微子是基本的马约拉纳粒子，证明轻子数不是守恒的。SNO+ 探测器将以不同的目标材料在三个不同的阶段运行：水、纯液体闪烁体和载碲的液体闪烁体。在水相期间，确认外部背景在预期范围内，对不可见核子衰变模式的特定通道设置了新的限制，测量了 Boron-8 太阳中微子通量并确认与之前的测量结果兼容。随着水相的完成，SNO+ 正朝着其主要的碲负载相迈进。这里，
