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
