This is Heling Zhu's sandbox to store studies in ATLAS Experiment.

Physics Analysis

Resonance search in low-mass 4-muon final states

Run-1 + data 2015/16 analysis

Data 2017 analysis

New baseline selection

Measurements of VBSVV semi-leptonics process

  • TWiki page
  • Supporting note
  • Paper published in Physics reivew D (PLD)
  • Paper approval meeting by Heling
  • Common Package for this analysis in reco-level: CxAODReader_VBSVV
  • Package for truth level study (fiducial space): xAODTruth_VBSVV
  • Tool for this analysis: To run systematic inputs with large variations, usually many jobs failed in lxbatch. One can use this tool to resubmit failed jobs quickly.
  • My works:
    • Event selection optimization, BDT and systematics studies in 2-lepton channel.
    • VBS theory cross section studies, theoretical systematics studies.

HZZ analysis

Off-shell Higgs analysis in data 2015+2016

EFT interpretation in unfolding Inclusive m4l in data 2015+2016
