Precision measurement of CP violation and branching fractions in $B^{\pm} \to K^0_{\mathrm{S}} h^{\pm}$ $(h = \pi, K)$ decays and search for the rare decay $B_c^{\pm} \to K^0_{\mathrm{S}} K^{\pm}$

LHCb 实验利用 13 TeV 质子 - 质子对撞数据，对 $B^{\pm} \to K^0_{\mathrm{S}} \pi^{\pm}$ 和 $B^{\pm} \to K^0_{\mathrm{S}} K^{\pm}$ 衰变进行了迄今最精确的测量，确定了其 CP 不对称性和分支比，并首次对稀有衰变 $B_c^{\pm} \to K^0_{\mathrm{S}} K^{\pm}$ 设定了上限。

Sharpening New Physics Searches in Neutrino Oscillations with DUNE-PRISM

本文研究表明，DUNE-PRISM 技术通过利用多离轴角测量来降低系统误差，能显著恢复 DUNE 实验在非幺正性和惰性中微子等新物理搜索中的灵敏度，尽管其对 $\tau$ 中微子扇区的改善有限，同时作者还发布了更高统计量的离轴中微子通量数据供社区使用。

Kitchen Sink Anomaly Detection

该论文通过引入新的模拟信号基准和高维且模型无关的“大杂烩”可观测变量集（结合能量流多项式与子喷注变量），显著提升了异常检测的灵敏度，并证明了基于属性袋装的集成方法能在大幅降低训练成本的同时保持相当的性能。
