Dear all,

  the following summarizes the main points of discussion at last 
week's first open toplhcwg, where action items from the group/experiments 
is needed.

-- decide whether to use BLUE for the cross-section combination. 
Aim, if possible, at having a combination for TOP2012
-- set-up a W helicity combination team
-- contact D0/CDF for the preparation of the first top mass world 
combination including the LHC.
-- finalize the definition of a common acceptance. Quote a value of the 
measured cross section in that acceptance
-- finalize the definition of a pseudo-top for unfolding purposes
-- provide cross section comparison to theory by using the PDG top mass 
value as a reference for both the experimental acceptance and the theory 
predictions
- single top combination: continue investigation on different sensitivities 
on b-tagging and TH uncertainties
- TH systematics: continue harmonisation where possible and use data to 
compare Q2/IFSR variation. Compare the effect of constraining with data 
as soon as possible
- investigate the dependence of the top mass on transverse momentum of 
top and b. Study particle multiplicities in top events.
- prepare future combinations in the Wtb vertex, single top tW, s-channel, 
ttbb, tt+boson

Let us remind everyone to subscribe to the new open email list
lhc-toplhcwg@cern.ch, where general interest topics will be discussed
and new open meetings announced. It is proposed to have the next one
in October.
