Plenary Talk - Physics Results with AD

This contribution discusses an anomaly detection search for narrow-width resonances beyond the Standard Model that decay into a pair of jets. Using 139 fb−1 of proton-proton collision data at sqrt(s) = 13 TeV, recorded from 2015 to 2018 with the ATLAS detector at the Large Hadron Collider, we aim to identify new physics without relying on a specific signal model. The analysis employs two...

Plenary Talk - Physics Results with AD

This work presents a strategy for model-independent searches for new physics using deep unsupervised learning techniques at the LHC. The first study applies a deep autoencoder to 140fb^-1 of sqrt(s)=13TeV pp collision data recorded by the ATLAS detector, selecting outlier events that deviate from the dominant Standard Model kinematics. Invariant mass distribuations of various two-body systems...
