Trigger Anomaly Detection for New Physics at the Large Hadron Collider
This dataset is a mirror of the Zenodo record: https://doi.org/10.5281/zenodo.21787779
This dataset contains Level-1 Trigger objects from the CMS experiment at the CERN Large
Hadron Collider, assembled for research on unsupervised anomaly detection in the
trigger. The goal of unsupervised anomaly detection in this context is the discovery of
new physics. This data set does not contain new physics. It is meant… See the full description on the dataset page: https://huggingface.co/datasets/CERN/anomaly_detection_cmsl1t.global-medicines-atlas-cms-partd-20260827
