Supersymmetry searches

Higgsino exclusion summary (Dec 2017). Stop exclusion summary (Dec 2017). High jet multiplicity event from SUSY-2016-13.

This page contains public results from the ATLAS SUSY Working Group. The group is responsible for searches sensitive to putative supersymmetry (SUSY) production including both R-parity conserving and violating scenarios, as well as long-lived (s)particles. Results from searches for (N)MSSM Higgs boson production can be found on the Higgs Results page. Non-ATLAS members looking for ATLAS results for conferences should contact the conveners: Zach Marshall and Federico Meloni. A list of conference talks and proceedings discussing ATLAS SUSY results can be found here: Slides, Proceedings, all ATLAS.

Auxiliary material

As part of ATLAS SUSY journal publications auxiliary material is made available in digital format via the HEPData project. This can be accessed via the “Documents” and then “Data points” links. The information in HEPData includes:

  • the observed and expected exclusion contour lines,
  • the observed upper limits on the signal model cross-section,
  • the acceptance and the efficiency (encapsulating detector effects) numbers for selected signal models,
  • detailed cut-flows for selected signal models (sometimes only in the “Auxiliary figures and tables” section of the public results webpage),
  • with the corresponding SLHA files (new HEPData: click on “Resources”-“Common Resources”),
  • [starting in 2017] code snippet with the implementation of the analysis selection at truth-level, as used to produce the acceptance numbers (new HEPData: click on “Resources”-“Common Resources”).

The acceptance is calculated using objects at truth-level following the definitions in ATL-PHYS-PUB-2015-013 with the following choices / minor modifications:

  • using `undressed’ leptons,
  • jets: excluding muons and neutrinos,
  • missing transverse momentum: include neutrinos from hadrons (e.g. from semi-leptonic b decays).
All experimental effects are absorbed in the so-called "efficiency", which is defined such that the product of acceptance and efficiency is the full selection efficiency calculated using reconstructed objects i.e. including all detector effects.

Filter Documents

Select the desired keywords to filter the results.
Selections within a section row are combined with a logical OR, while selections among different section rows are combined with a logical AND.
The "0 lepton" implies a lepton (typically el, mu) veto, while the "All hadronic" keyword describes analyses that are agnostic to leptons.
