1) pT spectrum in gg->ZH (A. Rizzi)

- gg->ZH shows strange peak at Higgs pT around 120GeV,
<- kinematics should be dominated by top, but the peak seems to be a bit low (Stefan).
- summed qq+gg->ZH contribution as a function of Higgs pT is not flat but shows peak around pT=120GeV, deviating +15/30% with respect to qq->ZH only contribution.
- gg->ZH inclusive contribution is O(10%) but here we are discussing boosted Higgs regime, thus gg->ZH contribution is even larger.

- Robert may be able to provide Higgs pT spectrum with VH@NNLO, but it uses heavy top mass limit. 
- Giancarlo should check the numbers if he reproduces the numbers (Stefan).

- Does public gg->ZH code exists (LO)?
- in the to-do list in HAWK for gg->ZH but not yet. Should not be complicated. (Stefan)
- Code is not public especially for ZH, but could provide Ntuple. (Giancarlo)
- perhaps no public code exists for MC+PS, neither MC@NLO nor MCFM(?)
--> asked Carlo Oleari for Powheg: gg --> ZH not available yet

- pT spectrum with/without jet-veto? (Andrea)
<- can be studied with gg->ZH LO + PS to estimate the effect (Massimiliano)
-> Giancarlo will do more investigation in few weeks.

Conclusion
- take central values as function of pT(H) from Giancarlo's result,
- apply average K-factor and assign conservative systematic uncertainty (1/2 of corrections?).

2) Dynamical scale choice (Giancarlo Ferrera)

- Has studied the dynamical scale choice effect in boosted regime (pV>200GeV) with 1) fixed scale as CERN Report 3 (mu^2=(MH+MW)^2) and 2), 3) dynamical scales with Higgs pT.
- indeed NNLO QCD corrections are small of below few % in any choice of scales of fixed or dynamical.
- also the difference in the NNLO cross section with different scales is 5.5% at most. 

- the argument by Massimiliano is that contrary to gg->H (large pT jet means large pT Higgs), it does not necessarily mean large Higgs pT with large jet pT because VH process is mediated via vector boson.
- thus the dynamical scale choice of MH^2+pTH^2 would not be a good choice for qq/gg->VH process. 
- even with jet-veto, Higgs pT would not change much thus does not expect much change (Massimiliano).

=> perhaps remain with fixed scale (with additional systematic uncertainty if necessary for scale choice?). 

Conclusion of 1) and 2)
- would like to have written prescription to be agreed among ATLAS+CMS+TH to survive for 2012 paper.
        - for gg-->ZH contribution, use parton level computation from first correction and refine later with LO+PS approach once available
           (at some point even NLO?)
- Andrea and Giacinto to further iterate with theory collegues.

3) qq/gg->WH/ZH cross sections at Ecm=13.0,13.5,14.0TeV with MH=125.0,125.5,126.0GeV were requested once again.

4) Powheg for the VH (WH/ZH) processes and the MiNLO approach which matches VH @ NLO and VH+1 jet @ NLO and LL PS is now available. This now adds up to the previously available Herwig++ (with powheg method) and the MC@NLO approaches (both only VH @ NLO). In none of these cases the gg-->ZH contribution is included.
