Description
Soft Unclustered Energy Patterns (SUEPs) are an unconventional signature that can arise in hidden-sector models with approximately conformal dynamics. Unlike traditional new physics signals, SUEP events are dominated by high particle multiplicities, low individual transverse momenta, and nearly isotropic energy flow, making them challenging to identify using standard reconstruction and analysis techniques at the Large Hadron Collider (LHC).
Previous experimental studies have begun to explore the phenomenology of SUEP-like signatures. In particular, the CMS Collaboration has performed a search targeting SUEP topologies using hadronic final states, demonstrating the feasibility of dedicated reconstruction strategies for diffuse, soft events. Complementary efforts within the ATLAS Collaboration also investigate SUEP scenarios with a focus on muonic final states, highlighting alternative experimental handles on hidden-sector dynamics.
This talk presents an ongoing analysis to characterize hadronic final state SUEP signatures in proton–proton collisions at √s =13 TeV using the ATLAS detector. A description of ongoing efforts will be presented, which aim to refine experimental tools for identifying SUEP signatures and to broaden the sensitivity of LHC searches to non-traditional manifestations of physics beyond the Standard Model.
