CDF Bayesian Neural Network WH Search with 4.3/fb - Systematics

 





Systematics

The following table shows the systematic uncertainity for each lepton/b-tag categories due to each effect on the signal acceptance.
  • Lepton reconstruction (Lep Reco)
  • Trigger
  • Initial and final state radiation, and Parton distribution functions (ISR/FSR/PDF)
  • Jet energy scale (JES)
  • b-tagging scale factor

We further apply 6.0% integrated luminosity uncertainty for all lepton/b-tagging category.
