Anomaly detection in the searches for inelastic dark matter at Belle II — •Jonas Eppelt, Patrick Ecker, Pablo Goldenzweig, and Torben Ferber for the Belle II collaboration — Karlsruhe Institut for Technology, Karlsruhe, Germany

Inelastic Dark Matter (IDM) is a rather complex model containing two Dark Particles and two Mediators. Its expected signatures include one resonant and one non-resonant decay.

In this talk current efforts are presented to approach searches for IDM at Belle II with anomaly detection via machine learning. This approach aims to train algorithms on (simulated) background events in order to recognize previous unknown signals. It seeks to reduce limitations due to the chosen model and parameter space in searches for physics beyond the Standard Model.

The current status on employing anomaly detection in an IDM search at Belle II will be given.
