Complete Optimal Non-Resonant Anomaly Detection

2024 · arXiv (Cornell University)

We propose the first-ever complete, model-agnostic search strategy based on the optimal anomaly score, for new physics on the tails of distributions. Signal sensitivity is achieved via a classifier trained on auxiliary features in a …

Single interpolated generative model for anomalies

2025 · Physical review. D/Physical review. D.

A key step in any resonant anomaly detection search is accurate modeling of the background distribution in each signal region. Data-driven methods like CATHODE accomplish this by training separate generative models on the complement of …
