 top production (ttbar and single top)
 ---------------------------------------

  - better models of event characteristics
    Currently use LO PYTHIA/HERWIG/ALPGEN.
    What physics is included?  What's not?
    Investigate MC@NLO ttbar production

  - top mass - control of systematic errors

  - single top "aiming for discovery"
    analysis techniques for difficult signal
    extend already good dialogue with theorists


 top properties
 --------------
  - How well can we measure Vtb, (Vts, Vtd)? 
  - Is there any shot at the t-t-Z vertex before a linear collider? 
  - What kind of bounds on anomalous gluon couplings can we expect from Tevatron?


 W+jets, Wbb+jets, Wcc+jets, Wc+jets
 -------------------------------------
 - major backgrounds to top properties (cross-section, W helicity,
 single top) and new physics (Higgs, anything with lepton, MET and jets)

 NLO exists for W+2jets and Wbbar
  - how can we use it in analyses? eg single top search
  - check assumptions for ttbar background estimates

 LO Matrix Element

  - How to combine events generated with different numbers of b, c and
 jets? This is a big problem for background calculations and kinematic
 modeling. Test approaches suggested by Mangano and CKKW and others...
 Choice of scale?

 top as a background to new physics
 ----------------------------------

 - How good do models of tt, ttj and ttjj (background to qqH->qqWW at for low
 mass Higgs search in first years of LHC) have to be? 
 - Can we test the theoretical predictions for ttbar and single top? 
 (A lot of LHC Higgs physics these days relies on the W-fusion
 production modes.) 

 PDFs
 ----

 - top is a clean way to study PDFs at high x, which is definately of
 interest for LHC.  Single-top in the t-channel is perhaps a unique way to
 measure the b PDF at high x, which can be important for Higgs physics, etc.

 W mass
 ------

 - Study of different methods (traditional M_T method vs cross section ratios, p_T
 distributions etc.), what can we learn from Tevatron
 - What needs to be done to get ready for LHC (improved Monte Carlos, combination of RESBOS 
 (QCD) and WGRAD/ZGRAD (EWK), inclusion of higher orders (QED) etc.).
 

 Other W/Z topics
 -----------------
 - measurements of triple gauge boson couplings, asymmetries, total cross sections. 
 - What can we learn about PDFs and new physics (e.g. search for anomalous TGCs, extra 
 gauge bosons) ? 
 - W and Z events as luminosity monitors.
