Description

Various theories beyond the Standard Model predict new physics phenomena that require dedicated and unconventional reconstruction techniques and background estimation strategies. Examples include displaced decays from long-lived particles scenarios or Dark Matter models where the target particles fall below standard trigger thresholds. These signatures often challenge traditional search strategies and demand innovative approaches to detection and analysis. The talk will focus on the most recent results using 13 and 13.6 TeV pp collision data collected by the ATLAS detector.

Many extensions of the Standard Model predict new heavy particles that could appear as resonances decaying into quarks, leptons or photons, or phenomena that require dedicated and unconventional reconstruction techniques and background estimation strategies. Examples include displaced decays from long-lived particles scenarios or Dark Matter models where the target particles fall below standard trigger thresholds.. The talk will focus on the most recent results using 13 and 13.6 TeV pp collision data collected by the ATLAS detector.
