    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.
