To do list for paper

Time scale: end of March/beginning of April (Higgs approval 29 Mar)

  • b-tagging scale factors: got final b-tagging scale factors yesterday

  • There will be a new update in next few days but only for c-tag SFs for JetFitterComb - doesn’t affect us

  • METUtility: will move to new version for final analysis run

  • Jet pileup correction: to be applied for final run – finally not much improvement (if any) but already in the code

  • Di-b-jet mass scale: will apply 5% correction to m(b,b)

  • Top normalization scale factors:

    • Changing to new method to improve consistency with W+jets and with ZH->lvbb analysis

  • ΔRjj study: look again at low ΔRjj region to answer EB questions

  • Limits:

    • Cross checks ongoing, but looks like asymptotics not good enough – differences between Lianliang and Silje because of Asimov set determined at different values of mu (?!)

    • Giacinto trying different approach but no agreement

  • Smoothing of backgrounds:

    • Previously done in llbb/lvbb but not on vvbb – need input from stats forum!

  • Theory uncertainties should be revisited slightly: to do

  • Boosted H->bb – lots of interest from elsewhere!

    • Hope will converge in Summer

    • Not many people…

  • ttH activity ramping up

    • Similar to vector-boson like quarks but different enough to make it a Higgs analysis

    • Could have results for summer maybe

  • Z->bb having difficulties:

    • Bug found in g->bb samples – being re-generated

    • Re-produced AFII g->bb – bad description of data

  • Possible Technicolor interpretation of H->bb

    • Thinking about this
