摘要

在现代粒子物理学中，寻找超越标准模型的物理学是一个非常热门的话题。到目前为止，BESIII实验已经收集了世界上最大的𝐽/ sarah和sarah(3686)共振数据集。庞大的数据样本和干净的反应环境为寻找新物理学提供了理想的场所。我们报告了最近对不可见衰变𝐽/ → +不可见的搜索和对重子扇区Λ→不可见的首次搜索。

Search for invisible decays at BESIII

Search for physics beyond the standard model is a highly topical in modern particle physics. So far, BESIII experiment has collected the world’s largest data sets at the 𝐽 / 𝜓 and 𝜓 (3686) resonances. The huge data samples and a clean reaction environment provide a ideal place to search for new physics. We report recent searches of the invisible decays 𝐽 / 𝜓 → 𝛾 + invisible and the ﬁrst search for the Λ → invisible in the baryon sector.
