Description

Foundation models have the potential to expand the discovery reach for new physics searches. In this paper, a full physics analysis using CMS Open Data is carried out to search for new physics in dijet events using the OmniLearned foundation model. We find that the background estimation describes the data well in validation regions, but is unable to accurately model the signal region where a significant excess is observed.
