6. Update sim web page
7. Update BgsApp documentation
8. TCL parameter documentation
9. Persistence of geometry parameters
10. All-in-one-step executable
11. Performance improvements to BgsG4Extension

ALL:

1. Rerun old requests which had invalid filter requests
2. Generate dec files as needed and requests for validation requests
3. Material studies:
   • e+e- -> gamma gamma - 100K (gamma_pair.tcl)
   • bhabhas - 100K (bhabha_generic_lumi_c.tcl)
4. Alignment studies:
   • dimuons - standard - 50K (mu_pair.tcl)
   • dimuons - no boost, no rotation, 0 beam size - 50K ()
   • dimuons - as above, no radiation, no multiple scattering, no interactions, no decays - 50K ()
   • dimuons - as above, const. BField - 50K ()
5. Resolution studies:
   • D* cocktail - 20K (B0B0bar_Breco_DX+DstarX_cocktail.dec)
   • B -> JpsiK+ - 20K (B+B-_JpsiK.dec)
   • D* decays (.dec files from Owen Long):
     20K (ccbar_Dstar+_D0pi_D0Kpi.dec)
     20K (ccbar_Dstar-_D0pi_D0Kpi.dec)
     20K (Ups4S_Dstar+_D0pi_D0Kpi.dec)
     20K (Ups4S_Dstar-_D0pi_D0Kpi.dec)
     
   • B0 -> D*pi, D0 -> K pi, K 3pi
6. Different hadronic models

PEP:

1. Extend geometry beyond Q1

SVT:

1. RF shield (in sim, isn't in reco)
2. fix ribs -- done
3. Validate alignment
4. Document
5. Refine geometry hierarchy to improve performance
6. Cables and matching cards
7. In BgsSvtSim, remove dependency on SvtSimGeomP

DCH:

1. Investigate why there are so many DchGHits -- done
2. Correct gas container material -- done
3. Investigate the effect of Diffuse vs. discrete wires
4. Volume optimization
5. Model of inert material needs improvement (electronics, cables,...)

Tracking:

1. de/dx validation
2. Tracking performance memo -- mostly done
3. Multiple scattering lateral displacement (BgsG4Extension/G4)
4. Overall comparison project

DRC:

1. Improvements to bulkhead geometry

EMC:

1. Overlaps
2. Parameterized lateral em showers
3. Compare performance with bbsim: EMC only
4. Native G4 coding

IFR:

1. RPC updates -- done mostly
2. Geometry of upgrade model -- done
3. Cryo-tower details -- done
4. Coil geometry
5. Persistance

SimApp:

1. Subsystems: degrade performance to look like data
   • SVT -
   • DCH - resolution smearing and inefficiency in SimApp.
   • DCH - dedx
   • DRC - smearing currently done in Bear
   • EMC - RUN2 feature extraction code in EmcSim
   • IFR -
   • L1 - trigger upgrade
2. EvtMix:
   • emc digi mixing with multiple input collections - fixed
   • mix tsf digis
   • mix prior to L1 sim. Requires DCH waveforms
   • extend to handle GHit mixing

ProdTools:

1. spruns --hidden needs to be fixed so we don't need --hidden to list G4 runs
2. spupdate needs to be fixed to handle bogus
3. spclean can't handle bogus (all options)
4. saveDir probably won't work with bogus ...
5. WEB CGI to produce inventory
6. Filter requests
