flag CERN's ATLAS experiment finds no evidence of supersymmetry, setting tighter limits on hypothetical particles using LHC data and machine learning.

flag The ATLAS Collaboration at CERN has set some of the strongest limits yet on supersymmetric particles using machine learning and data from the Large Hadron Collider’s 2015–2018 run. flag Researchers searched for signs of charginos and neutralinos decaying into low-energy particles, including "disappearing tracks" from pions and two low-momentum leptons, but found no evidence of supersymmetry. flag The results tighten constraints on the masses and lifetimes of these hypothetical particles, improving sensitivity to faint signals and guiding future experiments at the LHC and beyond.
