While in general it is to hoped that experiments will correct for detector effects, producing particle-level measurements valid within some systematic uncertainty, this is not always the case. Some key measurements only exist in uncorrected form, and a detector smearing or acceptance needs to be applied to theoretical/MC results before they can be compared to the data. Also, in some phenomenological evaluations of possible new measurements, it is desirable to have a rough simulation to estimate their robustness against detector effect.

We propose to evaluate tools in this area, and examine the requirements they might need to meet. A key issue is likely to be a standard output format for "reconstructed" objects such as jets, missing transverse energy etc.

  • Review of physics requirements
    • Acceptance, resolution, trigger and reconstruction efficiency
    • Granularity
    • Magnetic field
    • B-tagging
  • Review of Software Requirements (integration into tool chain)
    • Standardized input from generators (HepMC? At what level? Final state particles?)
    • Standardized output to Rivet and/or user code (TBD?)

We should define use cases, when is it a good idea for theorists to worry about detector simulation etc. Interested people (session 1) Simon Dean, Jon Butterworth, Peter Loch, Fabio Maltoni, Matthew Schwartz, Steve Mrenna, Andy Buckley.
