MVA preparation

  • VBF character

two forward jets with high pT and great Y separation,higgs in central region

  • 6 variables:mjj,Δηjj,PTt,Δϕγγ,jj,ΔRminγ,j,η*
  • η*=ηγγ-0.5*(ηj1+ηj2)

qualification task

  • ITK only simulation->digitization-

>reconstruction

  • check out InDetPhysValMonitoring and

draw some plots

  • need to talk with Andreas to understand

the plot
