Contents

Existing Codes and Implementations

  • Are all interesting models currently implemented?
    • non-minimal models like hidden valley or quirks?
    • need for modified shower or fragmentation models?
  • Update the Durham / Les Houches BSM Tools repository: Les Houches BSM Tools Repository

Framework for new model implementations

  • Status of QNUMBERS approach: arXiv:0712.3311
  • Implementation of arbitrary models as an evolution of the BSM-LHEF
    • Feynman rule packages: LanHEP, FeynRules
    • spectrum calculators
    • (matrix element) generator interfaces
    • interfaces to parton showers and hadronisation models
    • generator validation strategies
  • incorporation into validated generator versions used by experiments

SM for BSM (with Session 1)

  • Automated ME+PS matching for BSM processes
  • Boosted hadronic decays of BSM particles and decay products
  • BSM applications of New Jet Algorithms
  • Impact of MC tuning / uncertainty evaluations, on New Physics searches and measurements?

Detector simulation (with Session 1)

See Fast Detector Simulation Specification and Usage.

Flavour Les Houches Accord

  • With Tools WG of Flavor/LHC workshops. Model independent parametrization of flavor related quantities such as Wilson coefficients, exp. results, etc. Modify existing SLHA "structure" to host this accord? S. Heinemeyer, N. Mahmoudi.

Common non-susy BSM scenario and benchmark points

  • Define & generate some benchmark common data sets?
  • Discussion (accord?) on how experiments and theory might best interact on new model testing

Training

  • Possible training sessions on how to go from a model to event generation with new tools
    • Feynman rules: FeynRules, LanHep
    • spectrum calculators
    • MC generators: Herwig, Pythia, Sherpa, Whizard, MadGraph ...
    • detector simulation: Delphes
