    Tentative Agenda

The following is a tentative list of priorities, which may serve as a starting
      point for discussion towards adopting a simulations agenda:
Short-term
priorities
Long-term
goals
Software Development
Calculations
Software Development
Calculations
1. Interface to HGEANT 1. Preparing for the first test run:
Beam particles? Energies? Angles?
What to expect?
1. Link with theoretical models
(e.g. medium effects, QMD, BUU etc)
1. Heavy-ion reactions
2. Consolidate GEANT geometry 2. Detector efficiencies
& normalization
2. Enable heavy-ion calculations 2. Background calculations (combinatorial, conversion)
3. Consolidate GEANT digitizers 3. HADES reaction-dependent 
Filters (pion/proton beam)
3. Build data bases for:
  • Branching Ratios
  • Form Factors
  • Spectral Functions
  • In-medium elementary cross sections
  • 3. Pion-beam physics
    4. Interface to HYDRA 4. Reference trajectories 4. Enable automatic selection of the decay path for a given beam and target  
    5. GUI 5. Multiplicities, resolution etc. for DLS reactions (e.g. Ca+Ca) with partially completed spectrometer (e.g. 2 sectors, no MDC-4) 5. Develop high-level (physics) analysis tools and merge with the analysis framework  
    6. Enable non-isotropic decays 6. Alternative to GEANT:
    Polynomial fits for  fast tracking 
    through the HADES media
    6. Additional sources (e.g. thermal, cosmics)  
    7. Additional decay modes
    (e.g. VDM Dalitz distribution)
       

        Goals of the Workshop

    Identify a  "Simulations" team:
            Learn of the activities of Collaboration members
            with an interest on issues related to simulations.
    Adopt a common framework:
            A common simulations platform will facilitate
            acceptance studies and guarantee consistency
            in comparisons of results among detector groups.
    Set priorities:
            Agree on a tentative agenda for simulation software
            development and calculations, distribute tasks,
            set deadlines, and arrange for regular future contacts
            to report progress.
    Identify liaisons:
          Appoint a contact person from each detector group
            to import the simulation software to their group, and
            communicate requests to the developers.
