TP EM Containment

Discussion during a University of Rochester Group Meeting on March 26, 2008, regarding the correlation between resolution and asymmetricity in high-energy containment study. Points raised about negative asymmetricity, over-containment with infinite Hcal, calibration challenges at high energy, and potential solutions involving recalibration of Tracker and Ecal.

  1. TP EM Containment Jaewon Park University of Rochester Rochester Group Meeting Mar 26, 2008

  2. Containment • Added 4 Hcal configuration.

  3. Resolution and asymmetricity • Resolution and asymmetricity are correlated. • High energy show low-side tail. (negative asymmetricity)

  4. Containment at high energy • I stopped update points because it shows over-containment for infinite-hcal at infinite Hcal. • Calibration seems problem at high energy.

  5. Different curves converge to ~0.975 at low energy. • Changing only Hcal calibration doesn’t help much. • Tracker + Ecal recalibration at high energy can help?
