    • indico 26 Aug 2021 WG meeting
• A note on particle "status codes" in HepMC and Delphes
  • [1]
  • The Particle branch of the DELPHES output root file contains all generated particles
    • if(particle->Status==4)// Beam particle
    • ...Status==1 // undecayed particle
    • ...Status==2 // decayed physical particle (e.g. pi0, K_S, but not quark, gluon...)
  • use these codes to assess CORE reconstruction resolution
