2010.1.25 Mon. Review of Jet, Tracking DPG

Review of Jet Related meetings
  • Jet Algo (2009/12/17)
    • Association of Tracks to Jets (Salvatore Rappoccio)
    • Early Dijet Analysis with 900 GeV data (Philipp S.)
    • Calorimeter JetID Studies with 900GeV data (Kalanand Mishra)
  • Jet Algo (2010/01/14)
    • Tracker base jet id selection
    • Noise Studies in 900GeV data (Kalanand Mishra)
    • Calorimeter SimHit Level Jet Studies (Sharma Seema)
      • In MC, "Low EMF jets are an artifact of the ZS of ECAL and the low energy deposited by the particles traversing the detector. The jets are fine otherwise"
      • Therefore the low EMF cut actually removes a significant fraction of good jets in MC
      • The shape of EMF looks more like soft "single" hadrons which futher confirms that we are mostly seeing soft "isolated-kind of" hadrons (or accompanied by very soft particles) in 900 GeV MinBias sample.
  • Interesting Sw they used
Jet Analysis Winter Conference Plans
  • See Philipp's talk
    • pas twiki:
    • Philipp thinks that dijet study is almost as clean as Z to mumu, and little jet id cuts are needed. On the other hand, the inclusive jet spectrum has no handle on kinematics signatures and is more susceptible to fake jets due to detector noise. Thus a tight jet id criterion is needed.

Jet ID

Review of Detector Performance on 900 GeV data 2009

ReReco in 3_3_6_patch3 and Tracking Problem

  • PH-DPG Tracking Meeting (2010/01/25)
    • In News/Announcements, talks about the pixel triplet problem due to the very offset beam spot.
    • "Basic" tracking distributions and primary vertex resolution with collision data
  • JetMET
    • Validation of Data Re-Reco and new MC
      • Didn't see much change
      • From tracking talk we see that jet reco is ok b/c the tracks are later recovered in pair seeding.
    • In Philipp's talk, "Plans for Jet PAS for Winter Conferences", slide on "Data & MC Samples"
      • He says jetmet will stick with this sample for the winter conference plots b/c it's ok for jet reco.
