1) D0Sim Milestones:

• D0GSTAR without Digi Packages. Shuichi reported he took out Digi packages and made new release for D0gstar.
• Prototype D0Sim program, which includes:
  • 1st version pile-up package
  • Existing Digi packages: (sftdigi_reco, fpsdigi, cpsdigi, muo_digi)
  • CalWeight package
  Serban reported that a prototype D0Sim is already put into cvs and will be in the next release.

2) Subdetector's concerns on noise, efficiencies and pileup:

• Calorimeter: Marek reported the purpose, status, plans and manpower for calorimeter Pile-up in detail. Here is the summary of his talk.
• cps: Don Coppage reported cps digitization status. Works done beyond the current production MC:
  • Nearst neighbor crosstalk
  • Photo Statistics
  • Stereo angle bug for Z<0 fixed
  All the above iterms are in the current releases. But not turned on and not extensively tested. The pile-up will be their future work.
• fps: Dennis Shpakov reported that the situation with the FPS noise simulation package is pretty much the same as with the CPS: no real numbers characterizing noise and inefficiencies exist so far. The plan is to have methods to simulate cross talk between neighboring strips as well as fiber attenuation and reflection in fpsdigi by March 15 with some reasonable default parameters. As for the pileup, there is no FPS specific part of the problem: hits from the min. bias events should be added to SimFPSHitChunk and will therefore be picked up by fpsdigi automatically.
• Muon: no report from muon group.
• cft: no report from cft group.
• SMT: Ela reported that Anatoly Solomin will work on SMTdigi package, which is a conversion of the current SMT digitization from Fortran to C++ and will include SMT noise and ineficiency in the simulation. Anatoly just came from Moscow and will work here for three months for this project.
