ATLAS sets strong limits on supersymmetry
- ATLAS used machine learning to probe low-energy particles and improve sensitivity in SUSY searches at the LHC.
- The searches examined disappearing tracks from chargino decays and low-energy leptons from heavier neutralino decays.
- No evidence of SUSY particles was observed in either search.
- The results tighten limits on the masses and lifetimes of charginos and neutralinos.
- The new limits surpass older bounds set by the Large Electron–Positron Collider, the LHC’s predecessor.
- Results help guide future SUSY searches at the LHC and the High-Luminosity LHC.
- The Moriond conference featured the presentation of these SUSY search results.
- The higgsino remains a central focus in SUSY searches due to its connection to dark matter.
- The analysis used data from the LHC’s second run collected between 2015 and 2018.
- The effort aims to explore the potential mirror world predicted by supersymmetry.
