Conformal calibration and look-elsewhere effect in anomaly detection for new-physics searches

本文提出了一种基于符合预测（conformal prediction）的校准层，该层能将未经校准的机器学习异常评分转化为具有统计严谨性、无分布限制的局部和全局 p 值，从而有效地纠正背景误建模和“寻找别处效应”（look-elsewhere effect），以防止在新物理搜索中出现虚假发现。

Optimal binning of $D\rightarrow K_{\mathrm S}^0\pi^+\pi^-$ and $D\rightarrow K_{\mathrm S}^0K^+K^-$ phase space for experimental measurements

本文针对 $D \rightarrow K_{\mathrm S}^0\pi^+\pi^-$ 和 $D \rightarrow K_{\mathrm S}^0K^+K^-$ 衰变的 Dalitz 图提出了新的优化分箱方案，通过利用改进的品质因数，在考虑探测器分辨率和背景效应的情况下，预计可使 $\gamma$ 测量的精度提高 5%，并使粲混合可观测量（charm mixing observables）的统计灵敏度提高 20%。
