  1. How to proceed with MC for STAR forward upgrades?

  2. Geometry (from decadal plan): FSC FGT Extension Forward Tracking PID

  3. How to proceed? • Put oversimplified models for every detector (for example, ignore all mechanical details), run MC and try to optimize. Faster to implement, but will results be credible? • Or, include to best of our knowledge details, may be start with overkill parameters in terms of resolutions, granularities for future optimization. More work, but should provide more reliable results. • Some sort of combined scheme.

  4. Questions for slide 2: • What minimal configuration is required to do physics simulations? • What must be in the geometry file (details) and what can be omitted (assuming needed information will be accessible in geant output somehow)?

  5. FGT Extension (example): Six additional GEM discs. Required input: dimensions, positions, pixels size. What degree of details should be in the description (foil thickness, gas thickness, mechanical support, readout)? Can existing FGT geometry be simply reused with shift/spread along Z? Or, something simple can be implemented? Who will collect all required information? Who will put geometry in place?

  6. PID and Forward Tracking: • PID, low-mass RICH, what model to put in? • Forward Tracking, same questions as for FGT extension; dimensions, positions, pixel size. What level of details (technology) to include? Is simple sensitive pixels (yes/no for charge particles) is enough? Should we worry about albedo (mechanical details)? Etc… Who will put conceptual requirements? Who will put models in geometry description?

  7. Forward Spaghetti Calorimeter:(see Jay’s slides) • From stand alone MC no optimization yet, require more work, more people should be involved. • However, current parameters (granularity and resolution) may be an overkill already. • Proceed with implementation of current model? • UCLA will provide all known details about hardware.

  8. FMS, FHC. • FMS, detailed description exists? • FHC – same question, put simplified model, or put all know details. (Can we take care of collecting all info about FHC?)
