New Physics at the LHC
The New Physics part will meet at Les Houches during the period 17-26 June 2009, but people should form an idea of the studies they would like to pursue before that. All work should be completed by the end of 2009. The preference will be for studies focused on recent developments in new physics possibilities.

BSM with top:

Work Topics & Wish Lists
Boosted W/Z:
Theorists' wish list:
- Efficiency & background rejection for boosted Z to ee, mumu, bb; W and Z to qq (non-bb); what is the jet mass resolution vs jet pT for merged jets from color singlet objects?
- Can we identify something like u' -> Wu, W->e/mu nu? (MET will be aligned with lepton/jet, use collinear approx & W mass to constrain fake MET?)
Experimenters' wish list:
- Exhaustive list of models producing boosted W and Z bosons (organized by other objects in the event), with x-section ranges.
Long-Lived Particles:
"If it can be short-lived, it can often also be long-lived"
Experimenter's wish list:
- Monte Carlo generators
Spin and Mass Reconstruction:
- With current mass methods developed for SUSY, what do you get for non-SUSY? (Tommaso)
- Comparisons of mass methods and where they work/fail (Bob)
- What about off-shell particles? (Singh)
From Signature to Model:
- Meet again Monday morning

(Before registration, we had listed some possibilities:
- Hidden valleys (and other models with long-lived particles) - New physics decaying to top quarks - Exotic quarks - 4th family (mirror or sequential) - LHC-dark matter: LHC signals related to hints from PAMELA, ATTIC, DAMA
Furthermore, it would be interesting to further develop guidelines for follow-ups after a potential discovery: if we see X then what should we look for?)
