New Approaches: Sessions I+II
Z. Bern and L. Dixon   (Conveners)

    A list of topics to be covered

• Recent improvements to twistor and analytic-based approaches
  
  •    four-dimensional unitarity method
  •    techniques for rational parts
  • d-dimensional unitarity
  •  factorization-based (bootstrap) methods
  • direct diagrammatic approaches
  •    new loop integration methods
• Automation and standardization of new approaches
•  Progress and prospects for attacking the unsolved problems from the 2005 Les Houches wish list:
  
  •  VV + 1 jet
  •   ttbb
  •  tt + 2 jets
  •   VVbb
  •   VV + 2 jets
  •   V + 3 jets
  •   VVV
•  Discussion of other important processes, such as multi-jets and V + 4 jets
• The issue of including masses in loops (e.g. the top quark) in the new approaches
• Maximizing information transfer between new approaches and more traditional ones,
    in order to improve both
• Discussion of any new formal developments, which may lead to new insights and further improvements; for example
  
  •   Lagrangian-based proofs of MHV and CSW rules
  •   Space-cone gauge
  •   Feynman tree and largest-time decompositions
• These topics will be helpful as a precursor to the
  GGI workshop on collider physics
