当我们只模糊地知道它应该是什么样子时,我们如何才能寻找新的物理学呢?我们如何进行公正且数据驱动的搜索?如果我们在数据中看到明显的异常事件,我们如何事后量化它们的“有趣性”?我们提出了一种同时解决上述每个问题的分析策略 (SLEUTH),并在费米实验室 Tevatron 的运行 I 中 D0 收集的数据中演示了其对 30 多个专有最终状态的应用。
How can we search for new physics when we only vaguely know what it should look like? How can we perform an unbiased yet data-driven search? If we see apparently anomalous events in our data, how can we quantify their ''interestingness'' a posteriori? We present an analysis strategy (SLEUTH) that simultaneously addresses each of these questions, and we demonstrate its application to over thirty exclusive final states in data collected by D0 in Run I of the Fermilab Tevatron.
