Release 2.0.0-dev (development release)

New features since last release

  • A module allowing for jet substructure studies has been implemented in MadAnalysis 5. (#13)

    • It includes the following fastjet-contrib functionalities:
      • VariableR: normal and expert mode
      • SoftDrop: expert mode
      • Clusterer: expert mode
      • Jet Filtering: expert mode
      • Reclustering: expert mode
      • Nsubjettiness: expert mode
      • Pruner: expert mode
      • Energy Correlator: expert mode
      • HEPTopTagger: expert mode
    • RecJetFormat has been wrapped with a PseudoJet structure to accommodate dynamic transition between two objects.

    All these methods can be used through the SFS interface.

  • Substructure and HEPTopTagger has been redesigned to be shared libraries, so that MadAnalysis could be compiled without these modules as well. (#63)

  • The tagger module has been redesigned to accommodate the features of substructure module. (#86)

  • Multi-level object tagging has been enabled through the SFS framework. (#97)

    • Option to activate charm-jet tagging has been introduced.
    • Option to use jet-based hadronic tau matching has been introduced.
  • Command to fix random seed has been added. (#86)

Improvements

  • The SFS libraries are now included in the file analysisList.h, instead of in the main analysis file. This leads to much cleaner and independent analysis construction. (#86)

  • Compilation time testing has been added for the jet Substructure and HEPTopTagger interfaces (#86).

Bug fixes

  • Various bugfixes for matching the numeric results to MA5 v1.10. (#97)

  • $M_{eff}$ definition has been fixed. (#86)
