Searching for natural supersymmetry using novel techniques
New ATLAS results with contributions from our group
19.02.2020
In yesterday's CERN LHC seminar, Jeanette Lorenz presented the latest results of the ATLAS Collaboration on searches for natural supersymmetry. Our group made major contributions to a search for top squarks, the supersymmetric partner particles of the top quark, with decays to a lepton. Exploiting advanced techniques, including the use of neural networks, the search obtains some of the strongest experimental constraints on top squarks in the world of particle physics. A more detailed overview can be found in the accompanying physics briefing released by the ATLAS Collaboration.
The plot above shows the observed and expected exclusion contours at 95 % confidence level from different searches for top squarks. The search for top squarks using decays to one lepton is shown in orange.
