This study presents an unsupervised machine learning method using generative models to subtract background noise from images of particle jets in calorimeter detectors at particle physics experiments. The approach demonstrates robust performance across different experimental conditions and datasets without requiring labeled training data, addressing a key challenge in identifying signals of interest in high-energy physics experiments. The technique shows improved generalizability compared to supervised methods when applied to new detector configurations or collision scenarios.


This method could significantly improve the accuracy of particle identification in experiments at facilities like the Large Hadron Collider, potentially enabling the discovery of new physics phenomena that are currently obscured by background noise. The unsupervised approach is particularly valuable because it reduces the need for extensive labeled datasets and adapts more readily to varying experimental conditions.
