- General
- The document should correctly point out ("sell") the potential of a LCF
- high centre-of-mass energies
- beam polarisation
- two detectors
- The 11 years at 250 GeV as in earlier run plans are not a due to a technical limitation of the ILC technology
- Higgs at 250 GeV
- The influence of the Z-pole results on the Higgs precision to be taken into account
- Relation "isolated" Higgs couplings and global interpretations (is maybe true for many topics)
- 2f and 4f including Z-pole and WW scattering
- Point out (at least in an outlook) how a signiicant increase in lumi could be beneficial for the W mass
- Higgs at highest energies
- Johannes reminded that new physics could shine up directly in \lambda_hhh even if the single Higgs couplings are standard
- Overlap with e.g. GW could/should become part of the paper
- top from threshold to highest energies
- Value of top coupling precision to discover new physics (e.g. compositeness)
- ttH and WW
- ttH could benefit from an overhaul (on theory and experimental side)
- What to do with expected precision of 1% at 1 TeV
- New physics models?
- tth (and top mass) important for parametric uncertainties
- WW polarisation fraction could be an important observable
- hadronic separation of W/Z (still) important topic
- WW->tt as a (new) topic (at least R.P. has never thought about it :-( )?
- BSM - Direct production of new particles
- FCNC should be mentioned (either here or under top)
- Discussion about balance between "reaction" to bumps at LHC and full scrutinisation of region between 100 Gev and 1 TeV to search for LHC Loopholes
- It was pointed out that the small and big hierarchy problem is still an excellent guide to search for new physics and this still implies new physics at the 1 TeV scale
- Global interpretation
- Seems to be important to define the scope of the global fits
- NLO SMEFT is newest development but not all corrections are known
- It was agreed that the prediction power of the global fits should also be demonstrated at the ecample of concrete models
- Photon-Photon interactions
- Non-collider experiments
- Discovery study of heavy mesons were pointed out
- Strong QED in beam-beam interactions (did I get this right?)
- Opportunity of fixed target experiments with high energetic positrons
