Description
The disappearing track signature, which arises from the decay of a long-lived charged particle to a neutral particle and particles with momenta below the reconstruction thresholds, is characteristic of many well-motivated models for physics beyond the standard model, including anomaly mediated SUSY breaking models, natural models of SUSY with light higgsinos, and dark matter models with mass-degenerate multiplets. This talk presents a search for disappearing tracks in the ATLAS detector using the full Run 2 dataset. The results are interpreted in the context of long-lived charginos produced either directly or in the cascade decay of heavy prompt gluino states.
