For general upgrade samples please see: https://twiki.cern.ch/twiki/bin/viewauth/Atlas/UpgradePhysicsActivities#Information_on_MC_samples

Here are the ITK specific samples:

Requested Samples:

samples (25k-100k events): pi, mu, (e) mu=1,140,200 (multi lepton samples with discrete energy values (as before)) ------> requested from Pippa?

Beamspot missing layer layouts (incl no stub) CMOS granularity layouts material variations (e samples) 100k: tt for b-tagging, high pT jet studies no stub layout CMOS granularity layouts

Geometry files to be put in svn


Note W.I.P = Work In Progress, T.B.S = To be started

Pixel service implementations
  • Can we simulate this?
  • Are all the proposed layouts “easily alignable”?


We are working on a standardized checklist to evaluate layouts:

  1. Tests to be passed in IDres before being passed to step 2. (e.g. hits, coverage, redundancy)
  2. Tests to be passed in FatRas before being passed to step 3. cross check IDRes results
  3. FullSim studies with single particles in ID only geometry: resolution check, fake rate check, compare single muons truth tracking with pattern reco
  4. FullSim studies with physics signals in ID only geometry
  5. Geometries passed to Upgrade Physics group for full studies.
