  Mono-Higgs discussion: ATLAS/CMS discussion on mono-Higgs
  Present:
  
  Benedikt, Eiko, Koji, Lars, Oleg, Uli
  
  The scope of the paper was discussed
  
  Generally, everybody agrees to have a scope as outlined above
  
  Split of material was discussed
  
  Preliminary splitting decided, see outline above
  
  General principle is to not duplicate labor
  
  Additional material for paper:
  
  explicit grid recommendation
  
  not mentioned explicitly in the email by the LHC DM WG
  
  but part of previous white paper
  
  Oleg will confirm with the organisers that we want it in
  
  Discussion about the maximum range of tan(beta)
  
  The large difference between fixed order results from Uli and MG results from Lars not yet understood but high up in Uli’s priority list for next weeks
  
  For the time being go wiht tanb<10 and then wait for the outcome of Uli’s study
  
  Generally, for mono-h not superexciting because bb provides moderate additional sensitivity, i.e. what is excluded with gg production is certainly excluded including bb
  
  Question whether the SMM should be part of the white paper
  
  Needs to be discussed in wider forum with LHC DM WG organisers
  
  General feeling that including SMM would create a feeling of a disbalanced paper given that the amount of studies which went into it is only a fraction of the 2HDM+a model
  
  The 2HDM+a model is complex and including another model may not add to the clarity of the paper
  
  Uli pointed out that the only signature that the model has beyond the 2HDM+a is VBF DM production
  
  Layout of contribution
  
  a short (1-2 paragraph) description of your most recently published analysis
  
  very brief, outline main discriminant observables + strategy
  
  [ATLAS+CMS]
  
  A few kinematic plots showing the behaviour of variables that are most relevant for your analysis as a function of the model parameters
  
  Essentially motivating the choice of the scan paramers
  
  the central part of the contribution
  
  parton-level plots showing the kinematic dependence like on on p7 of https://indico.cern.ch/event/678491/contributions/2778773/attachments/1552383/2439419/2017_11_03_WhitePaper_2HDMa_monoh_BRANDT.pdf
  
  parton-level since this is what was used to study the sensitivity to the model and to derive the grid
  
  [CMS: angle parameters sint and tanb (plots+text) and lambdas (for lambdas probably only text)]
  
  [ATLAS: mass parameters mA ma mH]
  
  Total and fiducial cross-section at parton level for the same grids
  
  For (mA,ma) plane only (representative illustration)
  
  [ATLAS since the grid is based on Lars’ studies]
  
  Signal efficiency at parton level with simplified analysis-like cuts for grids
  
  For (mA,ma) plane only (representative illustration)
  
  [ATLAS since the grid is based on Lars’ studies]
  
  (if available) sensitivity at parton level for the same grids
  
  No…
  
  Recommendation for the final scan including exact points (to be confirmed with LHC DM WG organisers):
  
  (mA,ma) plane
  
  (ma,tanb) plane
  
  sint 1D slices for representative mA,ma points

  Mono-Z discussion
  
  MonoZ_Whitepaper_151117.pdf
  People Present
  
  Yicheng, Koji, Chris, Alison, Michel, Ashraf, Andreas
  
  Scope of contribution
  
  Kinematic distributions
  
  Common variables: MET, Z PT, DeltaPhi(Z,MET)
  
  Leptonic only:
  
  Something sensitive to Z polarization, e.g. cos(delta_phi (l-,Z)) in Z frame
  
  Hadronic only:
  
  Jet properties, e.g. jet mass (only those that are ~reliable at particle level)
  
  Possible further content not yet decided on:
  
  Significance estimation
  
  Comparison of kinematic shapes to DMF pseudoscalar model
  
  Inclusion of tan(beta) scan (would have to also produce b enduced)
  
  Generation technical details
  
  Particle Level
  
  No ME jet for leptonic case
  
  Full process in MG, gluon only, no Madspin (generate g g > xd xd~ l+ l-)
  
  Action items
  
  Check interest from CMS mono-V(had)
  
  Converge on selection for hadronic and leptonic analyses
  
  Synchronize data cards and generation details
  
  Choose parameter points to look at
  
  Meet again in 1 or 2 weeks to discuss progress
