Upsilon Analysis in p+p 2009 - PID

Updated on Tue, 2012-03-27 16:41. Originally created by wimsatt on 2012-03-27 14:18. Under:
  • PID (Greg)
    • dE/dx
      • dE/dx vs p for the Upsilon triggered data
      • nsigma_dE/dx calibration of means and sigmas
        • Electron Mean: -0.263
        • Electron Width: - 1.016
        • Pion Width: 0.943
        • Hadron Width: 1.071
      • Cut optimization (Maximization of electron effective signal)
      • Final cuts for use in data analysis
    • E/p
      • E/p distributions for various p bins
      • Study of E calibration and resolution between data and embedding (for L0 Trigger systematic uncertainty)
      • Resolution and comparison with embedding (for cut efficiency estimation) (Kurt and Greg)
