Trigger Talking points

• Trigger
• At Level1, Level2, Level3
• What are the trigger terms?
• What are the rates ?
• What is the signal efficiency?
• In which stream the data will be available?
• What is the state of the trigger simulator code?
• How far can you run the package to get a
  rate/efficiencies?
• What data samples are needed to get the
  rates/eff. How many of each is needed?
• Whats the status of MC simulation for these
  signal and background events?
• How many events are currently available ?

3
Event Selection Talking points

• Offline Event Selection
• What are the objects available in the data?
• Which type of algorithms will be available as
  default?
• What needs to be available to rerun a given
  algorithm or a different one?
• What are the topological variable available for
  event selection?
• Are they in some Chunk or we need to develop code
  to access it?
• What information we need to have in the various
  levels of data storage formats for ease of event
  selection?
• In which stream the data will be available?

4
Object ID Talking Points

• Object ID
• What are the various reconstruction/id techniques
• Which ones are suited for top/Higgs?
• Is this the default method?
• Is the technique on a solid footing?
• How much work needs to be done?
• Which packages does this reside in
• What information do the Chunks contain?
• Is there something missing which could be useful
  for our analyses?
• How well does the simulation work for these
  objects
• Electrons/muons are too clean no noise?
• b-fragmentation models?
• Herwig vs Pythia vs isajet and other generators
• Efficiency
• Fake rates
