Probing scalar-neutrino and scalar-dark-matter interactions with PandaX-4T

本研究利用 PandaX-4T 实验的 $^{136}$ Xe 双 $\beta$ 衰变数据，开展了首次直接谱搜索，为低于 2 MeV $/c^2$ 的媒介子质量设定了迄今最严格的标量媒介中微子自相互作用限制，从而约束旨在解决哈勃张力问题的模型，并为标量媒介暗物质相互作用提供新的界限。

Study of the reactions $\bar{n} p \to 2\pi^{+}\pi^{-}$ , $2\pi^{+}\pi^{-}\pi^{0}$ , and $2\pi^{+}\pi^{-}2\pi^{0}$ using $J/\psi \to p \pi^{-}\bar{n}$

利用 BESIII 探测器采集的 $(10.087 \pm 0.044) \times 10^{9}$ 个 $J/\psi$ 事例数据集，本研究通过在动量范围延伸至 1174 MeV/ $c$ 的区间内测量 $\bar{n} p \to 2\pi^{+}\pi^{-}$ 、 $2\pi^{+}\pi^{-}\pi^{0}$ 和 $2\pi^{+}\pi^{-}2\pi^{0}$ 反应的截面，开创了在 $e^{+}e^{-}$ 对撞机上研究反中子 - 质子相互作用的先河。
