- QCD radiation patterns and New Showers: see below
Validity of tunes and Uncertainty Bands (Sessions 1 & 2)
- Automated Runing: Rivet & Professor (Session 1)
- Can we define regions of validity for the physics implemented in the MC? e.g. What about small x, high rapidity effects (Session 1)
- Can we obtain credible uncertainty bands with existing tools, or are new methods needed (Session 1)
- Impact of tunes on new physics searches (Session 2)
- Maybe we can produce "Demystifying Tuning: A Les Houches Guide to Tuning?" (Session 1)
Tuning in the presence of matching (Session 1)
- Chart the problem. Determine some Classic Examples.
- How dependent on matching strategy?
- Are there ways of revamping pre-matched tunes?
