John: Jet finding using Centauro algorithm

  • Goal: access TMD physics
  • Advantage of Centauro algorithm: it can properly capture the current jet and separate it from the beam remnant jets
  • An initial simulation study using 2000 events of SIDIS group simulation output with high Q2 and ECCE detector setup close to July concept
    • In full simulation: transformation from lab frame to Breit frame using truth and reconstructed e- information to obtain x, Q2, and virtual photon momentum
    • For truth information: transform the event generator frame to the lab frame and then to the Briet frame
    • Both calorimeters (mid rapidity and forward regions) and track jets are studied with a jet cone of 0.8 (may adjust the number in the later study)
    • Results agree well with Centauro paper
  • Discussion
    • Calorimeter jets results appear to have some noise. Need to figure out how to calibrate the calorimeter jet response
    • Low count in track jets. It could be an efficiency issue
There are minutes attached to this event. Show them.
