Description
Supersymmetry (SUSY) is one of the most compelling beyond Standard Model theories, addressing questions such as the hierarchy problem, dark matter, and unification of the fundamental forces. The ATLAS experiment at LHC has conducted a comprehensive and robust search for SUSY particles using pp collision data collected during Run 2 at \sqrt{s} = 13 TeV.
This talk will review the strategies and results of these searches, covering both strongly and electroweakly produced SUSY particles, in scenarios with R-parity conservation and violation. Special attention will be given to experimentally challenging, theoretically motivated signatures, including long-lived particles and compressed mass spectra.
Moreover, a collection of ATLAS SUSY searches are reinterpreted in SUSY models with the full range of RPV coupling strengths, covering scenarios with prompt, long-lived, and stable LSP. This provides a comprehensive assessment of the sensitivity of SUSY searches in ATLAS to signatures of RPV SUSY.
The IHEP SUSY group contributed to the analyses targeting the electroweak 1-lepton (1L), same-sign and three-lepton (SS/3L), and di-tau final states, as well as the RPC-to-RPV reinterpretation and the pMSSM reinterpretation, providing crucial sensitivity to a wide range of SUSY scenarios.
