Top analyses short of manpower in run 2

Below are the high-profile top analyses that are high-priority to be done with the run 2 data, but either have insufficient or no manpower.

  • Additional jets in tt events: e.g. gap fraction measurement.
    • Important QCD measurement to help understand top modelling and background to new physics searches.
  • ttV cross-section measurement.
    • Rare process that was just seen at the end of run 1 - run 2 gives a significant boost in the cross-section.
  • Differential cross-section measurements of ttbar production: boosted and resolved.
    • Vital to understand the modelling of ttbar events - in particular the top pT measurement, which was not well modelled in run 1.
  • Charge asymmetry (resolved) l+jets and dilepton.
    • Run 2 allows to explore to higher ttbar invariant mass and investigate potential new physics contributions.
  • Single-top associated Wt production cross-section measurements.
    • Observed for the first time at the LHC run-I. The increase of the cross-section at 13TeV should allow to perform precision measurements for total and fiducial cross-section, and could open the possibility to perform differential cross-section measurements.
  • Top mass measurements - all channels / methods.
    • One of the fundamental parameters of the SM that can be measured at the LHC. The huge statistics in run 2 open up possibilities for classic measurements and also new ideas.
