Scattering lengths beyond the nuclear scale and the Efimov effect

该论文探讨了中子与原子核在低能下可能产生远超核尺度的散射长度，并以 $^{17}$ B- $n$ 系统为例，分析了其巨大散射长度对 $^{19}$ B作为 $^{17}$ B- $n$ - $n$ 埃菲莫夫三聚体结构的潜在影响，从而为在原子核中观测埃菲莫夫效应提供了理论依据。

Combined Evidence for the $X_{17}$ Boson After PADME Results on Resonant Production in Positron Annihilation

该论文指出，PADME 实验在正电子湮灭中观测到的约 17 MeV 处的异常信号与核物理实验中观测到的 $X_{17}$ 玻色子迹象相互印证，结合两者后显著降低了 $X_{17}$ 玻色子质量的不确定度。

Measurement of coherent exclusive $J/\psi\to\mu^+\mu^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV with the ATLAS detector

ATLAS 实验利用 2023 年记录的 79 $\mu$ b $^{-1}$ 积分亮度数据，在质心能量为 5.36 TeV 的铅 - 铅超周边碰撞中测量了相干独占 $J/\psi\to\mu^+\mu^-$ 产生截面，结果显示其快度分布与理论预言基本一致，但在中心快度区域与 LHC 运行 2 的其他实验结果存在张力。
