Jet reconstruction

• reconstruct jet by using fastjet package
• Anti-kT method
• Minimum pT cut on track pT > 0.15 GeV/c
• R < 0.7

electron and Jet distance

• Calculate R (distance of electron and jet in phi & eta)
  • dphi = phi(e) - phi(jet), deta = eta(e) - eta(jet) & R = sqrt(dphi*dphi + deta*deta)
• Plotted the R if R < 0.7
• Electrons were separated semi-inclusive & photonic electron
  • photonic electron: identified by invariant mass method
  • semi-inclusive: removed reconstructed photnic electron via invariant mass
    • smaller photonic contribution than inclusive

• R distributions after dividing the number of entries

electron tagged jet pT

• plotted jet pT if the distance of jet and electron (R in the upper plots) is less than 0.7.
  • assumed tagging electron in the jet
• Reference: Cone pT (Summing tracks w.r.t electron in R<0.7)
