论文摘要
本文报告是由于搜索了\ snoplus {}检测器中使用所有可用数据的$^{16} $ o核从$^{16} $ o核中消失的搜索。这些所谓的“无形”衰减不会直接沉积能量在检测器中，而是通过随后的核去激发和伽马射线排放来检测。部分生命时给出了新的限制：$τ（n \ rightarrow Inv）> 9.0 \ 9.0 \ times10^{29} $年，$τ（p \ rightArrow inv）> 9.6 \ times10^{29} $年$年，$τ（nn \ rightarrow inv（nn \ rightarrow inv） 6.0 \ times10^{28} $年，$τ（pp \ rightarrow inv）> 1.1 \ times10^{29} $年$年度在90 \％贝叶斯信誉级别（速率为先前的统一）。除了（$ nn \ rightarrow Inv $）外，所有结果都在现有限制上提高了约3倍。
This paper reports results from a search for single and multi-nucleon disappearance from the $^{16}$O nucleus in water within the \snoplus{} detector using all of the available data. These so-called "invisible" decays do not directly deposit energy within the detector but are instead detected through their subsequent nuclear de-excitation and gamma-ray emission. New limits are given for the partial lifetimes: $τ(n\rightarrow inv) > 9.0\times10^{29}$ years, $τ(p\rightarrow inv) > 9.6\times10^{29}$ years, $τ(nn\rightarrow inv) > 1.5\times10^{28}$ years, $τ(np\rightarrow inv) > 6.0\times10^{28}$ years, and $τ(pp\rightarrow inv) > 1.1\times10^{29}$ years at 90\% Bayesian credibility level (with a prior uniform in rate). All but the ($nn\rightarrow inv$) results improve on existing limits by a factor of about 3.
