New jet tree format

Description can be found here

Jet finder Run 6 configuration

Jet tree branches

  • track/tower pT > 0.2 GeV
  • trigger IDs: See the list below
  • all primary vertices with rank > 0
  • hadronic correction: 100% subtraction scheme
  • track |DCA| < 3 cm
  • pT-dependent DCAxy cut
  • track (number of hits) / (number of possible hits) > 0.51

  • track/tower pT > 0.2 GeV
  • trigger IDs: JP1, L2JetHigh, BBCMB-Cat2 (luminosity monitor)
  • all primary vertices with rank > 0
  • hadronic correction: 100% subtraction scheme
  • track |DCA| < 3 cm
  • pT-dependent DCAxy cut (a la Run 6 with slight tuning around 0.5 < pT < 1.5 GeV)
  • track chi^2 < 4
  • track (number of hits) / (number of possible hits) > 0.51
