Energy fraction by type in Gen Jets:
GenJetEfrac.gif GenJetEfracLog.gif

  • Had: pions, kaon, protons and neutrons
  • EM: gamma,electron
  • Inv: muons and neutrinos
  • Aux: everithing else, including resonances - sigma, lambda, etc.,

Comments: Invisible energy (neutrinos and muons(*) ) is below 1%. Aux has decay modes with pi,p,n,pi0, if add it to EM and Had the energy distribution could be described with the proportion: EM 30%, Had 70% for Pt 20:150 GeV range.

Average particle energy by type.
Particle with similar response in calorimeters are combined.
