Search for new phenomena in two-body invariant mass distributions using unsupervised machine learning for anomaly detection at √s =13TeV with the ATLAS detector

Show other versions (429)

Searches for new resonances are performed using an unsupervised anomaly-detection technique. Events with at least one electron or muon are selected from 140 fb−1 of 𝑝⁢𝑝 collisions at √𝑠=13 TeV recorded by ATLAS at the Large Hadron Collider. The approach involves training an autoencoder on data, and...
