Observation of the charmless purely baryonic decay $\mathinner{\mathit{\Lambda}^0_b\!\to \mathit{\Lambda} p \overline{p}}$

利用 LHCb 实验的质子 - 质子对撞数据，研究人员以 5.1 倍标准差的显著性观测到了无粲纯重子衰变 $\mathinner{\mathit{\Lambda}^0_b\!\to \mathit{\Lambda} p \overline{p}}$ ，并首次测量了其相对于 $\mathinner{\mathit{\Lambda}^0_b\!\to \mathit{\Lambda} K^+ K^-}$ 的分支比。

Production of $D_s\bar{D}_s$ and $D\bar{D}$ bound states in the $B$ decays within the Bethe-Salpeter framework

本文利用 Bethe-Salpeter 框架和单玻色子交换模型研究了 $B$ 介子衰变中 $D_s\bar{D}_s$ 和 $D\bar{D}$ 束缚态的产生，发现尽管 $D\bar{D}$ 束缚态在所有耦合参数组下均存在，但 $D_s\bar{D}_s$ 束缚态仅局限于特定的参数区域，其预测的分支比范围为 $10^{-6}$ 至 $10^{-4}$ 。

Landscape of Spontaneous CP Violation

本文综述了超对称框架内自发 CP 破坏的实现，阐明了其如何解决强 CP 问题、产生 CKM 相位，并通过 Affleck-Dine 机制成功解释宇宙重子不对称性，同时预言了可探测的中子电偶极矩。

Differential measurements of $\gamma\gamma\to\tau\tau$ and constraints on $\tau$ -lepton electromagnetic moments in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV with ATLAS

利用 1.93 nb $^{-1}$ 的 Pb+Pb 碰撞数据（ $\sqrt{s_{_\text{NN}}} = 5.02$ TeV），ATLAS 合作组首次给出了 $\gamma\gamma\to\tau\tau$ 产生的微分事例率测量结果，并提取了对 $\tau$ 轻子反常磁偶极矩和电偶极矩的约束，这标志着电偶极矩在重离子碰撞中的首次测量。
